Technology and industrial pioneers

TL;DR. This chapter closes out the book's new "People who shaped history" part with nine people (ten, counting Wilbur and Orville Wright as one entry) who built the companies, machines, and platforms that most people now use without a second thought, in the industrial and digital ages alike: an oil empire that fueled the twentieth century, a telephone network, a moving assembly line that put a car within reach of an ordinary wage, the first powered flight, a compiler that let people program in something closer to English, an animation studio and a theme park, the personal computer and the smartphone, and a hyperlinked web with a shared address system underneath it all. None of them built alone, and few of their stories are simple triumphs. Rockefeller's oil monopoly was broken up by the same courts he had outmaneuvered for decades. Ford's production genius sat next to a documented campaign of antisemitic publishing. Disney's studio built a global entertainment empire while fighting a bitter strike by its own animators. Jobs's products changed how people carry and use computers while his management style wore down the people who built them with him. Gates fought the United States government over Microsoft's market power before redirecting most of his fortune to global health. After this chapter, the book leaves individual biography behind and returns to the present, to geopolitics as it stands today.

Key takeaways

Rockefeller and Ford pioneered organizational forms (vertical integration, the moving assembly line) that later industries across the world copied, and both had a documented ethical or legal reckoning: Standard Oil's court-ordered breakup, Ford's antisemitic publishing.
Bell, Hopper, and Berners-Lee each built an infrastructure layer so basic to daily life that it goes unnoticed: a telephone network, the first compiler, and the hyperlink and web address.
The first powered flight and the rise of the personal computer and smartphone share a pattern: years of unglamorous engineering work behind one celebrated public moment.
Market dominance invited legal scrutiny more than once in this chapter. Standard Oil's 1911 breakup and Microsoft's antitrust case eight decades later both turned on the same question: when does a company's success cross into illegal monopoly?
Not every legacy here sits comfortably next to the achievements. Ford's antisemitism, Disney's clash with striking animators, and Jobs's harsh treatment of colleagues are all part of the honest record, not footnotes to it.
Two of the era's richest men redirected their fortunes toward public health: Rockefeller's philanthropy helped found modern medical research and disease eradication campaigns, and Gates's foundation has funded much the same fight a century later.
Tim Berners-Lee's decision to give the Web away royalty-free is the rare case here of choosing openness over personal enrichment, and it shaped how open today's internet became.

John D. Rockefeller (1839-1937)

Key facts:

Bookkeeper turned oil magnate who founded Standard Oil in Cleveland, Ohio, in 1870
Consolidated dozens of rival firms into the Standard Oil Trust (1882), a structure that gave English the word "trust"
Standard Oil controlled roughly nine-tenths of American oil refining by the 1890s
In 1911 the U.S. Supreme Court broke Standard Oil into 34 companies for violating the Sherman Antitrust Act, yet his personal wealth rose afterward
Gave away much of his fortune through the Rockefeller Foundation (1913), funding medical research and public health campaigns
Legacy split between a monopolist who prompted a landmark antitrust ruling and a pioneer of large-scale, professionally run philanthropy

John D. Rockefeller grew up in modest circumstances in upstate New York and got his start as a bookkeeper and produce merchant in Cleveland, Ohio. He entered the oil business in the early 1860s, just as refined kerosene was becoming the country's main source of household light in the years before electric lighting reached most homes, and in 1870 he and a small group of partners incorporated Standard Oil. Over the next two decades he built it into the dominant force in American oil, refining and distributing the overwhelming majority of the kerosene and other petroleum products used in the United States, at a time when oil meant light and lubrication for machinery rather than gasoline for cars, since the automobile age was still decades away.

Rockefeller's method was not a single invention but a set of practices that became templates for big business afterward. He drove down costs relentlessly and used that cost advantage, along with secretly negotiated freight rebates from railroads, to undercut competitors until they sold out or folded. He then organized dozens of formerly separate companies into a single, tightly managed structure called the Standard Oil Trust (1882), a legal innovation that let one board control many nominally independent firms and that gave the English language the word "trust" as shorthand for a large, concentrated business combination. By the 1890s, Standard Oil controlled somewhere around nine-tenths of American oil refining. The same decades saw American industry mechanize and consolidate on a large scale, following the factory system that the Industrial Revolution had already brought to Britain and continental Europe; Rockefeller's oil empire is one of the clearest American versions of that same shift from workshops to giant, centrally managed firms.

That scale drew scrutiny. The journalist Ida Tarbell, whose own father had been a small oil producer squeezed out by Standard Oil's tactics, published a detailed exposé of the company's history in 1904 that helped turn public and political opinion against it. In 1911, the U.S. Supreme Court ruled that Standard Oil violated the Sherman Antitrust Act of 1890 and ordered it broken into 34 separate companies, among them firms that later became ExxonMobil, Chevron, and Amoco. The breakup did not ruin Rockefeller; his stock in the successor companies rose in combined value and he remained, by most estimates, the richest person in the world for years afterward (some later calculations, adjusted for the size of the American economy at the time, rank him as the wealthiest individual in modern history).

Rockefeller's rise coincided with, and helped define, the era American historians often call the age of the "robber barons," a label applied to a handful of industrialists (Rockefeller in oil, Andrew Carnegie in steel, Cornelius Vanderbilt in railroads and shipping) whose fortunes and methods drew both admiration for what they built and lasting criticism for how they built it. Rockefeller himself rarely answered his critics in public and left the company's day-to-day defense to subordinates, a habit that only deepened his reputation as a remote, calculating figure even as he became the country's best-known businessman.

In his later decades Rockefeller gave away much of that fortune, on a scale that had no real precedent among American businessmen. The Rockefeller Foundation, founded in 1913, funded medical research, public health campaigns against hookworm and yellow fever across the American South and abroad, and the General Education Board, which helped build the university that became the University of Chicago and supported schooling in the rural South. A related institution, the Rockefeller Institute for Medical Research (now Rockefeller University), became one of the country's leading centers for biomedical research. Together these set a pattern for large-scale, professionally run philanthropy, run by paid staff pursuing measurable goals rather than by the founder's personal charity, that wealthy industrialists after him, Bill Gates among them nearly a century later, would follow closely. His legacy today is split cleanly down its two halves: a monopolist whose business practices were serious enough to prompt one of the most consequential antitrust rulings in American history, and a philanthropist whose foundation helped build much of the modern infrastructure of medical research and public health.

Alexander Graham Bell (1847-1922)

Key facts:

Scottish-born inventor and educator of the deaf who founded the Bell Telephone Company in 1877
Filed his telephone patent on February 14, 1876, and made the first successful call days later to his assistant, Thomas Watson
Held dozens of other patents: the photophone, hydrofoil boat designs, a metal-detecting device, and early aircraft experiments
His patent claim is contested: rival inventor Elisha Gray filed a notice describing a similar device the same day, and historians still dispute the exact sequence
Advocated oralism in deaf education, suppressing sign-language instruction for generations, a stance many deaf advocates today regard as damaging
Bell Labs, the research arm his company later spawned, produced the transistor and information theory; his telephone is the direct ancestor of every voice call made today

Alexander Graham Bell was born and raised in Edinburgh, in Scotland, the son of a family deeply involved in the study of speech and elocution. His father developed a system for teaching deaf people to speak, and Bell carried that interest with him when the family emigrated first to Canada and then to the United States, where he taught at a school for the deaf in Boston (his mother and, later, his wife were both deaf, and that closeness to hearing loss shaped much of his working life). Experimenting with ways to transmit sound electrically, Bell filed a patent for what became the telephone on February 14, 1876, and days later made the first successful call to his assistant, Thomas Watson, famously asking him to come to the next room.

Bell's telephone patent became the foundation of the Bell Telephone Company, founded in 1877, which grew into the corporate ancestor of American Telephone and Telegraph (AT&T) and, later, the research powerhouse of Bell Labs. Growth in the first years was slow, since telephones only worked between subscribers connected to the same local switchboard, and it took manual switchboard operators and, later, automatic switching equipment to link callers across whole cities and eventually across the country; by the time Bell died in 1922, telephone lines already reached millions of American homes and businesses, a network built by the company that bore his patent long after he had personally moved on to other pursuits. Beyond the telephone, Bell held dozens of patents and pursued an unusually wide range of interests: an early photophone that transmitted sound on a beam of light, hydrofoil boat designs, a metal-detecting device built in a failed attempt to locate the bullet lodged in President James Garfield, and early aircraft experiments through the Aerial Experiment Association he helped found. He also served for years as president of the National Geographic Society.

Don't be confused: Bell's telephone patent has a real, documented rival claim. On the very day Bell filed his patent application, a competing inventor named Elisha Gray, working for Western Union, filed a notice describing a similar device for transmitting speech electrically. Historians still argue over the exact sequence of filings that day and whether Bell's patent lawyer saw details of Gray's design before Bell's application was finalized. Bell's patent held up through hundreds of legal challenges over the following years, and he is the one credited in most histories, but the dispute over who actually got there first is genuine and unresolved to most historians' full satisfaction, not a matter this book can settle.

Bell largely stepped back from active management of the telephone business within a few years of founding it, handing day-to-day control to other executives while he pursued his other interests, but the research arm that eventually grew out of his company, Bell Labs, went on to produce some of the twentieth century's foundational technologies in its own right, among them the transistor and the information theory that underlies digital computing, decades after Bell himself had moved on to airplanes and hydrofoils. Bell also remained active in deaf education for the rest of his life, work that some of his own descendants and disability historians have since criticized: Bell was a prominent advocate of oralism, the view that deaf people should be taught to speak and lip-read rather than use sign language, a position that suppressed sign-language education for generations of deaf students and that many deaf advocates today regard as one of the more damaging chapters in the history of deaf education, alongside his more celebrated invention.

Bell's telephone network reshaped how people communicate over distance, laying groundwork that the telegraph had only partly built, and the company structures that grew out of his patent dominated American telecommunications for over a century, until AT&T's own court-ordered breakup in 1984. The instrument itself, refined many times over, remains the direct ancestor of every voice call made today, including the ones now carried over the internet that Tim Berners-Lee's web helped popularize.

Henry Ford (1863-1947)

Key facts:

Michigan machinist who founded the Ford Motor Company in 1903, his third attempt at building a car business
Introduced the moving assembly line at Highland Park in 1913, cutting car-assembly time from around twelve hours to roughly ninety minutes
The Model T (1908) sold more than 15 million units by 1927 and put car ownership within reach of a middle-class income
Paired the assembly line with the 1914 "Five Dollar Day," roughly doubling the standard factory wage
From 1919 owned the Dearborn Independent, which published antisemitic material including "The International Jew"; documented to have influenced Hitler, who awarded Ford a state honor in 1938
Fought unionization for years, including the 1937 "Battle of the Overpass"; Ford Motor did not sign a union contract until 1941

Henry Ford grew up on a farm outside Detroit, Michigan, and worked as a machinist and engineer before founding the Ford Motor Company in 1903, his third attempt at building a car business. His breakthrough was not the automobile itself but a production philosophy: build one model, keep it simple and durable, and drive its price down year after year by manufacturing it at enormous scale. The Model T, introduced in 1908, embodied that philosophy and became the car that put automobile ownership within reach of a middle-class income for the first time.

Don't be confused: Ford did not invent the automobile. Working automobiles with internal combustion engines predate Ford by roughly two decades; the German engineer Karl Benz patented his three-wheeled Motorwagen in 1886, and several other European and American inventors built running vehicles before Ford ever founded a car company. What Ford pioneered was not the car but a way of making it: the moving assembly line, introduced at his Highland Park plant in 1913, which brought the work to stationary workers on a conveyor system instead of having workers move to a stationary vehicle. It cut the time to assemble a car from around twelve hours to roughly ninety minutes and became the template for large-scale manufacturing worldwide, a shift that grew directly out of the same drive toward mechanized, factory-based production that reorganized Europe's economy a century earlier.

Ford paired the assembly line with the "Five Dollar Day" in 1914, roughly doubling the standard wage for his factory workers. The move was partly a response to exhausting turnover on the punishing new assembly line, but it also had a broader effect: it gave Ford's own employees enough income to become customers for the cars they built, helping seed the mass consumer economy that defined much of twentieth-century American life. Ford pushed the same logic further at the giant River Rouge complex outside Detroit, which by the late 1920s took in raw iron ore, rubber, and glass at one end and turned out finished cars at the other, a degree of vertical integration few companies before it had attempted. The production system built on the Model T and the moving line, often called Fordism by economists and historians, spread far beyond Ford Motor and even beyond capitalist economies: Soviet planners under Lenin and Stalin studied and imported American assembly-line methods for their own industrialization drives, an odd twist for a system built by a famously anti-socialist businessman.

The Model T itself changed everyday life well beyond the factory that built it. Ford sold more than 15 million of them between 1908 and 1927, famously offered for years in "any color that customer wants, so long as it is black," since a single, fast-drying black paint fit the pace of the assembly line better than a wider palette did. Cheap, reliable car ownership on that scale pulled paved roads out into rural America, moved shopping and work further from where people lived, and set in motion the suburban, car-centered pattern of daily life that much of the United States, and eventually much of the world, still follows today.

Ford's public life outside the factory floor was similarly restless. In 1915, hoping to end the First World War through moral pressure rather than combat, he funded and sailed on a chartered ocean liner nicknamed the "Peace Ship" to Europe with a group of activists, an effort to broker a negotiated peace that dissolved in disorganization and press ridicule almost as soon as it landed. The episode did little lasting damage to his business reputation, but it is a reminder that Ford's ambitions, and his occasional lack of judgment about them, reached well past cars.

Ford's record carries a second, much darker chapter that belongs in any honest account of his life. Starting in 1919, Ford owned a newspaper called the Dearborn Independent, which he used through the 1920s to publish antisemitic conspiracy material, including a serialized version of the forged tract known as "The Protocols of the Elders of Zion" and a series later compiled into a book called "The International Jew: The World's Foremost Problem." These writings circulated widely, were translated into German, and are documented to have influenced Adolf Hitler, who reportedly kept a portrait of Ford in his office in Munich and is the only American named favorably in "Mein Kampf." In 1938 the German government awarded Ford the Grand Cross of the German Eagle, a state honor for foreigners that Ford accepted and did not return even after the Kristallnacht pogrom later that year. Facing a lawsuit and a public backlash, Ford closed the Dearborn Independent in 1927 and issued a signed apology retracting the antisemitic claims; biographers disagree about how sincere that retraction was, since associates reported his private views changed little afterward. Ford's company also fought unionization for years through his Service Department's use of intimidation, culminating in the 1937 "Battle of the Overpass," in which his agents beat organizers from the United Auto Workers outside the Rouge plant; Ford Motor did not sign its first union contract until 1941.

Ford's dual legacy is inescapable and this book states both halves plainly: a manufacturing innovator whose assembly line reorganized industry worldwide and helped create the American middle class, and a publisher of antisemitic propaganda whose material reached, and by the documentary record influenced, one of history's most destructive regimes. Both facts are part of the same life and neither cancels the other out of the record.

Wilbur Wright (1867-1912) and Orville Wright (1871-1948)

Key facts:

Dayton, Ohio bicycle mechanics who treated flight as an engineering problem, building their own wind tunnel to test dozens of airfoil designs
Flew unpowered gliders at Kitty Hawk, North Carolina from 1900 to 1902, logging more than a thousand flights before ever attaching an engine
On December 17, 1903 achieved the first sustained, controlled, powered flight; Orville piloted the first (120 feet, 12 seconds) and Wilbur the longest (852 feet, 59 seconds)
Succeeded where the federally funded rival Samuel Langley failed; his Aerodrome crashed into the Potomac River twice just days earlier
Spent years defending their patents, including a long, bitter legal fight with rival Glenn Curtiss that some historians say slowed American aviation's progress
Wilbur died in 1912; Orville lived until 1948 and long disputed the Smithsonian's since-corrected claim about which aircraft flew first

Wilbur and Orville Wright ran a bicycle repair and manufacturing shop in Dayton, Ohio, when they turned their attention, in the late 1890s, to the problem of powered flight. Where earlier experimenters had mostly guessed at wing shapes or flown gliders without real control, the Wrights built their own wind tunnel and systematically tested dozens of airfoil designs, treating flight as an engineering problem to be solved through careful, disciplined data collection rather than through brave leaps of faith. Their key insight was that a flying machine needed to be controllable in three dimensions at once, and their system of wing warping, combined with a moveable rudder and elevator, let a pilot bank, turn, and climb in a way no earlier design had achieved.

The brothers chose Kitty Hawk on North Carolina's Outer Banks for its steady winds, soft sand for landings, and isolation from prying reporters, and they spent three full seasons there, from 1900 to 1902, flying unpowered gliders and logging more than a thousand flights before they ever attached an engine. That patient, unglamorous testing program, refining one wing shape after another against their own wind-tunnel data, is what let them succeed where better-funded rivals failed. The most prominent of those rivals, Samuel Langley, secretary of the Smithsonian Institution, had received a substantial federal grant to build a powered aircraft called the Aerodrome; it crashed into the Potomac River on two separate public attempts in 1903, just days before the Wrights' quiet success at Kitty Hawk, a contrast between generously funded failure and self-financed achievement that newspapers of the time found irresistible once word of the brothers' flights finally spread.

On December 17, 1903, at Kill Devil Hills near Kitty Hawk, North Carolina, the brothers flew their powered aircraft four times. Orville piloted the first flight, which covered 120 feet and lasted 12 seconds; Wilbur piloted the fourth and longest, covering 852 feet in 59 seconds. It was the first sustained, controlled, powered flight of a heavier-than-air machine in recorded history, a threshold that connects directly to the human drive to reach ever further that also runs through the explorers and space pioneers chapter elsewhere in this part.

Don't be confused: Wilbur and Orville's roles were not identical, but neither brother's contribution stands alone. Wilbur was the elder brother and, by most accounts, the more forceful theorist and negotiator in the partnership's early years; Orville piloted the very first powered flight on December 17, 1903, while Wilbur piloted the longest flight of that same day. The two men worked so closely, testing ideas against each other constantly and sharing credit on their patents, that historians generally treat the achievement as inseparable between them rather than crediting one brother as the primary inventor and the other as an assistant.

The world outside Kitty Hawk barely noticed at first; American newspapers were skeptical of a claim with so few witnesses, and it took the brothers several more years of public demonstration flights, including a 1908 U.S. Army contract for the first military airplane and a celebrated tour of exhibition flights across Europe, to convince the public and the press that sustained, controlled flight was real. After 1903 the brothers spent years refining their aircraft and defending their patents in court, including a long and bitter legal fight with rival aviation pioneer Glenn Curtiss that some historians argue slowed American aviation's progress relative to Europe's in the years before the First World War. Wilbur died of typhoid fever in 1912, before aviation's rapid wartime and postwar growth. Orville lived until 1948, long enough to see the jet age begin, and spent much of his later life in a dispute with the Smithsonian Institution over its early, since-corrected claim that a different aircraft had been the first capable of flight; he only allowed the original 1903 Flyer to return to the United States and the Smithsonian shortly before his death. Every airliner, cargo plane, and orbital rocket that has left the ground since traces its lineage to the control principles the two brothers worked out at Kitty Hawk.

Walt Disney (1901-1966)

Key facts:

Midwest-born artist who co-founded the Walt Disney Studio in Hollywood in 1923 with his brother Roy O. Disney
Created Mickey Mouse in 1928 and released "Snow White and the Seven Dwarfs" in 1937, the first full-length, cel-animated feature produced in the United States
Opened Disneyland in 1955, setting the template that nearly every theme park built afterward has followed
In 1941 his animators went on strike; Disney later testified before HUAC alleging Communist influence, and some strike leaders were frozen out of the industry
The 1946 film "Song of the South" reflected racial caricatures common at the time and was withheld from official re-release for decades
Persistent claims of personal antisemitism remain, on the evidence available, unproven by biographers, unlike the well-documented case against Ford

Walt Disney grew up in the Midwest, worked briefly as a commercial artist, and after an early animation studio in Kansas City went bankrupt, moved to Hollywood in 1923 to try again with his brother, Roy O. Disney, who ran the business side of what became the Walt Disney Studio for decades. Walt supplied the creative vision: Mickey Mouse, introduced in 1928's "Steamboat Willie," was among the first animated cartoons synchronized with sound, and Disney followed it with "Snow White and the Seven Dwarfs" in 1937, the first full-length, cel-animated feature produced in the United States and a film whose commercial success proved that animation could sustain a feature-length story rather than only short cartoons. Disney followed "Snow White" with "Pinocchio" and "Fantasia," both released in 1940; "Fantasia," which paired abstract animation with classical orchestral music, lost money on its initial release but is now widely regarded as one of the most technically ambitious animated films of its era. During the Second World War, Disney's studio largely converted to government work, producing training films and propaganda shorts for the U.S. military and Treasury Department, including films that encouraged Americans to pay their income taxes. Disney went on to build an entertainment company that spanned feature films, nature documentaries, and television, then reinvented the amusement park with Disneyland, which opened in 1955 and set the template, meticulously designed themed lands, tightly controlled guest experience, that nearly every theme park built afterward has followed in some form. Late in his life he also planned an ambitious, only partly realized "Experimental Prototype Community of Tomorrow," a working city built around new technology and urban planning ideas; after his death the concept was scaled back into the EPCOT theme park that opened in Florida in 1982, a fraction of his original, far more utopian vision.

Disney's record also includes a genuinely contested labor history. In 1941, animators at his studio went on strike over pay, credit, and working conditions, a dispute Disney took personally and bitterly; he later testified before the House Un-American Activities Committee in 1947, alleging Communist influence behind the strike's organizers, and some strike leaders found themselves frozen out of the industry afterward. Separately, some of the studio's early output reflected the racial caricatures common across American film in that era, most notably the 1946 feature "Song of the South," which the company withheld from official re-release for decades over its treatment of the Reconstruction-era South. Persistent rumors that Disney himself held personal antisemitic views have circulated for decades, but his most thorough biographers have found no solid documentary evidence to support that specific charge, unlike the well-documented case against Ford; the labor conflict and the studio's own dated racial content are the parts of Disney's record that historians treat as settled and serious, while the antisemitism allegation remains, on the evidence available, unproven rather than established.

The company Disney built is today one of the largest media and entertainment conglomerates in the world, owning film studios, television networks, and theme parks across several continents, and Disney's insistence that animation could be prestige storytelling rather than filler before a feature changed how the entire industry, and the artists profiled in this part's chapter on artists, writers, and musicians, think about what animated film can do. In one of this chapter's smaller ironies, the Walt Disney Company later bought Pixar outright in 2006, the same computer animation studio Steve Jobs had built up after leaving Apple decades earlier, a deal that made Jobs Disney's largest individual shareholder and briefly tied two very different pioneers profiled in this chapter to the same boardroom.

Grace Hopper (1906-1992)

Key facts:

Yale-trained mathematician (PhD 1934) who joined the U.S. Navy Reserve in World War II and worked on the Harvard Mark I
Built the first working compiler, A-0, in 1952, when most in the field assumed programming in words was impractical
Her work led to FLOW-MATIC and then COBOL (1959), which still runs today inside much of the world's banking, insurance, and government payroll systems
Popularized, though did not originate, the term "bug" for a technical fault after a moth was found in the Mark II's relay in 1947
Reached the rank of rear admiral (lower half) in 1985 and received the National Medal of Technology (1991) and, posthumously, the Presidential Medal of Freedom (2016)
The Grace Hopper Celebration, a major annual conference for women in computing, carries her name today

Grace Hopper earned a PhD in mathematics from Yale in 1934, an unusual accomplishment for a woman in that field at the time, and joined the U.S. Navy Reserve during the Second World War, where she was assigned to work on the Harvard Mark I, one of the earliest large-scale automatic computers, under the mathematician Howard Aiken. From there she moved into the earliest days of commercial computing, working on the UNIVAC at the company that became Remington Rand.

Hopper's central technical achievement was the compiler, a program that translates instructions written in something closer to human language into the raw machine code a computer actually runs. She built the first working version, called A-0, in 1952, at a time when most people in the field assumed computers could only follow numerical machine instructions and that the idea of programming in words was impractical; she later said she had to convince colleagues that the compiler would even work before she was allowed to spend real time building it. Hopper pushed the idea anyway, and her work led directly to FLOW-MATIC, an English-like language for business data processing, which in turn shaped the design of COBOL (Common Business-Oriented Language), released in 1959. Hopper spent much of the 1960s pressing the Navy and the wider computing industry to adopt COBOL as a shared standard rather than let every manufacturer keep building incompatible, proprietary languages, an early and largely successful push for what would now be called interoperability. COBOL is still running today inside a large share of the world's banking, insurance, and government payroll systems, decades after Hopper first argued that programming should read more like language than like arithmetic.

Don't be confused: Hopper's influence on how people actually write software is underattributed relative to her name recognition. Many readers know Ada Lovelace's name as an early visionary of what a computing machine might someday do, and rightly so; see the chapter on scientists, inventors, and mathematicians for her work and Alan Turing's alongside it. Hopper is less widely known outside computing circles, yet the compiler she built and the language design philosophy she pushed for are the direct ancestors of nearly every high-level programming language written since, the actual layer of software that most working programmers touch every day.

Hopper also popularized, though she did not originate, the term "bug" for a technical fault, after a moth was found lodged in a relay of the Mark II in 1947 and taped into the operating log; the word for a glitch predates that incident by decades, but the story and the physical specimen made her name inseparable from it. Later in her career she became a well-known lecturer and teacher within the Navy and the wider computing world, famous for handing audiences a foot-long piece of wire to illustrate the maximum distance an electrical signal can travel in a nanosecond, a physical prop meant to make the abstract cost of computing delay concrete for people writing software far removed from the underlying hardware. She remained in the Navy on and off for the rest of her career, repeatedly recalled from retirement because of her expertise, and reached the rank of rear admiral (lower half) in 1985, one of very few women to hold flag rank at that time. She received the National Medal of Technology in 1991 and, posthumously, the Presidential Medal of Freedom in 2016. A major annual conference for women in computing, the Grace Hopper Celebration, carries her name today and draws tens of thousands of attendees, a direct institutional link between her career and the effort to bring more women into the field she helped found.

Steve Jobs (1955-2011)

Key facts:

Co-founded Apple Computer in 1976 with Steve Wozniak, building the company's first successful product, the Apple II, largely on Wozniak's hardware design
Pushed the graphical interface he saw at Xerox into the Macintosh (1984), popularizing the GUI for ordinary consumers
Lost a power struggle with CEO John Sculley and left Apple in 1985; founded NeXT and bought Pixar, whose 1995 film "Toy Story" was the first feature made entirely with computer animation
Returned to Apple in 1997 and led the iMac (1998), iPod (2001), iPhone (2007), and iPad (2010)
Documented as a harsh manager; also orchestrated secret no-poaching agreements among Silicon Valley firms, settled for $415 million in 2015
Delayed conventional treatment for his 2003 pancreatic cancer diagnosis for roughly nine months in favor of alternative remedies, before dying of the disease in 2011

Steve Jobs was born in San Francisco and adopted as an infant by a working-class couple in what became Silicon Valley. He dropped out of Reed College after one semester, kept auditing classes informally, worked briefly at the video game company Atari, and traveled to India in his early twenties on a spiritual pilgrimage before returning to California and co-founding Apple Computer in 1976 with the engineer Steve Wozniak, building the company's first successful product, the Apple II, largely on Wozniak's hardware design while Jobs supplied the business drive and, increasingly, a strong sense for what a computer's design and interface should feel like to use. After a visit to Xerox's research labs exposed Apple's engineers to an early graphical interface controlled by a mouse, Jobs pushed the idea into the Macintosh, released in 1984, which did more than any other single product to popularize the graphical interface for ordinary consumers, even though Xerox, not Apple, had built the underlying idea first. The Macintosh sold below expectations, and in 1985 Jobs lost an internal power struggle with CEO John Sculley, the executive Jobs himself had recruited from Pepsi, and left the company he had co-founded.

Out of Apple, Jobs founded a workstation company called NeXT and bought the computer graphics division of Lucasfilm, renaming it Pixar; its 1995 film "Toy Story" was the first feature made entirely with computer animation. Apple bought NeXT in 1997 largely for its operating system technology, and Jobs returned to Apple, eventually as CEO, leading a run of products that remade the company and, in several cases, reshaped entire industries: the iMac (1998), Mac OS X (built on NeXT's foundations), the iPod (2001) and the iTunes Store, which upended how recorded music was sold, the iPhone (2007), which set the template nearly every subsequent smartphone followed, and the iPad (2010).

Jobs's management style is extensively documented, by colleagues, by journalists, and by his own authorized biographer, as demanding to the point of harshness: public dressing-downs of employees, a habit of dismissing work as terrible one day and brilliant the next, and a persuasive intensity coworkers nicknamed the "reality distortion field" for its ability to convince people of things that were not actually true yet. Several further episodes sit in the record alongside the products. Jobs denied paternity of his first daughter for years despite a DNA test showing an overwhelming probability he was her father, before eventually reconciling with her. In the mid-2000s he orchestrated secret agreements among several major Silicon Valley companies not to recruit each other's employees, a practice that suppressed engineers' wages and became, after his death, the subject of a class-action lawsuit that the companies involved settled for $415 million in 2015. And after his pancreatic cancer diagnosis in 2003, Jobs delayed conventional surgical treatment for roughly nine months in favor of dietary and alternative remedies, a decision several of his doctors and biographers believe may have worsened his prognosis; he died of the disease in 2011. None of this erases what Apple's products under Jobs changed about how people carry, use, and think about computers; it simply means the record includes both.

Bill Gates (b. 1955)

Key facts:

Seattle-raised Harvard dropout who co-founded Microsoft with Paul Allen in 1975
Licensed MS-DOS to IBM in 1980 on a non-exclusive basis, letting Microsoft's software become the standard across the whole IBM-compatible industry
Windows (1985) and Microsoft Office gave Microsoft a dominant position in operating systems and productivity software for decades
The U.S. Department of Justice sued Microsoft in 1998 for illegally using its Windows monopoly against rival browser Netscape; a 2000 breakup order was overturned, and the case settled in 2001
Stepped down as CEO in 2000 to focus on the Bill & Melinda Gates Foundation, whose vaccine funding is credited with helping prevent millions of childhood deaths since 2000
His documented meetings with convicted sex offender Jeffrey Epstein after Epstein's 2008 conviction drew sustained public criticism

Bill Gates grew up in Seattle and, as a teenager at a private school there, met Paul Allen while both were learning to program on one of the few computer terminals available to students at the time. Gates left Harvard University before finishing his degree to pursue the software business full time, and he and Allen co-founded Microsoft in 1975, initially writing software for the earliest hobbyist microcomputers. The company's defining early decision came in 1980, when IBM needed an operating system for its first personal computer and Microsoft, rather than building one from scratch, bought the rights to an existing system from a small Seattle firm and licensed it to IBM as MS-DOS, while keeping the right to license the same software to other computer makers. That non-exclusive licensing arrangement, more than any single piece of code Microsoft wrote, is what let the company's software become the standard across an entire industry of IBM-compatible machines rather than staying tied to IBM's own hardware. Windows, launched in 1985 and refined through several major versions over the following decade, and the Microsoft Office suite that followed it, gave Microsoft a dominant position in both operating systems and productivity software that lasted for decades. Windows' own graphical interface drew a lawsuit from Apple in 1988, which argued that Windows copied the visual "look and feel" Apple had built into the Macintosh; American courts ruled against Apple in the early 1990s, finding that Apple's own license agreements and the broader unavailability of copyright protection for a general interface style left it without a claim, a ruling that let Microsoft keep building on ground Steve Jobs believed Apple alone owned.

Windows' dominance drew a second, far more consequential legal challenge. The U.S. Department of Justice sued Microsoft in 1998, arguing the company had illegally used its Windows monopoly to crush the rival Netscape web browser by bundling its own Internet Explorer into Windows at no separate charge. A federal judge ruled against Microsoft in 2000 and initially ordered the company broken in two; an appeals court overturned the breakup order, and Microsoft settled with the government in 2001, agreeing to share technical information with competitors and accept conduct restrictions rather than being split up. European regulators pursued similar antitrust cases against Microsoft through the 2000s over comparable bundling practices, resulting in large fines.

Gates stepped down as Microsoft's chief executive in 2000 and gradually shifted his attention to the Bill & Melinda Gates Foundation, founded that same year with his then-wife Melinda French Gates, which grew into one of the largest philanthropic foundations in the world, funding vaccine distribution, malaria and polio control efforts, and agricultural development across the developing world, alongside domestic education initiatives in the United States. The foundation's vaccine funding, delivered largely through the global vaccine alliance Gavi, is credited by public health researchers with helping prevent millions of childhood deaths from preventable disease since 2000, even as some critics argue that a single private foundation wields outsized, largely unelected influence over global health policy and research priorities. In 2010 Gates and Warren Buffett launched the Giving Pledge, asking billionaires to commit most of their wealth to charitable causes. Gates and Melinda French Gates divorced in 2021, and Gates's documented meetings with the convicted sex offender Jeffrey Epstein after Epstein's 2008 conviction, meetings Gates has said were limited to discussions of philanthropic funding, drew sustained public criticism and reporting; Gates has denied any deeper relationship, but the association is well enough documented in reputable reporting that this book records it rather than leaving it out. His two legacies sit side by side much like Rockefeller's a century before him: an antitrust case built on real findings of anticompetitive conduct, and a philanthropic operation, similar in scale and ambition to the work covered in the chapter on human-rights leaders and social reformers, that has measurably reduced deaths from preventable disease.

Tim Berners-Lee (b. 1955)

Key facts:

British physicist working at CERN who circulated the proposal for the World Wide Web in March 1989: HTML, HTTP, web addresses, and the first browser and server
The first website went live in August 1991, built and run on one of Steve Jobs's NeXT computers
In 1993, at his urging, CERN placed the Web's underlying technology into the public domain, royalty-free, a choice widely credited with letting the open Web outgrow its licensed rivals
Founded the World Wide Web Consortium in 1994 to steward open standards and was knighted in 2004
Has since criticized how a handful of large platforms concentrated control over the open system he gave away for free
Remains active through the World Wide Web Foundation and the Solid project, which aims to give individuals technical control over their own personal data

Tim Berners-Lee, born in London and educated in physics at Oxford, was working as a software contractor at CERN, the European particle physics laboratory in Switzerland, when he confronted a mundane but pervasive problem: thousands of researchers using incompatible computer systems needed a way to share and link documents across all of them. In March 1989 he circulated a proposal (his supervisor famously scrawled "vague but exciting" across the top of it) that became, over the following two years, the working core of the World Wide Web: HTML for writing linked documents, HTTP for transferring them, web addresses to locate them, and the first web browser and server, built and run on one of Steve Jobs's NeXT computers, the same machine line whose operating system later became the foundation of Apple's own software. The first website went live in August 1991.

The decision that did the most to shape what the Web became was not technical but was Berners-Lee's own: in 1993, at his urging, CERN placed the Web's underlying technology into the public domain, royalty-free, so that anyone could build a browser, a server, or a site without paying a license fee to CERN or to him personally. Rival hypertext systems being developed commercially around the same time carried licensing restrictions the Web never did, and many historians of computing point to that single choice, made deliberately rather than by accident, as the reason the open Web won out over its more closed alternatives and grew as fast as it did. Berners-Lee founded the World Wide Web Consortium in 1994 to steward open standards for the technology he had given away, work that connects directly back to the foundational computing ideas covered in the chapter on scientists, inventors, and mathematicians, where Alan Turing's and Ada Lovelace's theoretical groundwork for computing itself is covered. He was knighted in 2004, becoming Sir Tim Berners-Lee, and appeared as himself at the opening ceremony of the 2012 London Olympics, typing the words "This is for everyone" on a period keyboard in front of a global television audience, a rare instance of an inventor's private choice about his own creation being celebrated as a matter of national pride. He remains active through the World Wide Web Foundation and a later project called Solid, which tries to give individuals technical control over their own personal data rather than leaving it locked inside the databases of the large platforms built on top of his invention, and he has been an outspoken advocate for net neutrality, the principle that internet providers should treat all traffic equally rather than favoring some services over others.

Berners-Lee's own view of his creation's legacy has grown more complicated over time. In public statements and writing over the past decade, he has repeatedly criticized how a handful of large platforms have concentrated control over how people actually experience the open system he gave away, arguing that the same royalty-free openness that let the Web spread so widely also left it without any built-in defense against that later concentration. Whether an inventor's original act of generosity can be blamed for choices made by others decades afterward is a fair question this book leaves open rather than settling; what is not in question is that an overwhelming share of the sites and services in daily use worldwide, from news archives to banking portals to the tools used to research this book, exist on infrastructure Berners-Lee built and then declined to charge anyone to use.

That is the last of the twelve chapters on individual figures in this part of the book, a closing thought on people who spent their working lives building the roads, wires, factories, and platforms the rest of us now move through without thinking twice, and with that we return from the people who built the past to the world as it stands today 👉 Geopolitics today
