He had built one of history's most dominant technology companies, then redirected his wealth entirely toward global health.
From a Seattle childhood spent teaching himself to code, William Henry Gates III built one of the most dominant technology empires in history, only to redirect that fortune toward the quiet, unglamorous work of saving lives. By the time he stepped away from Microsoft's boardroom in 2020, he had donated $54.8 billion through his foundation to vaccines, global health, and climate solutions — a second career that may outlast the first in consequence. His story raises an enduring question about wealth and responsibility: what does a person owe the world once they have taken so much from it?
- A teenager who taught himself to code became, by thirty-one, the youngest billionaire in America — a rise so swift it outpaced the institutions meant to govern it.
- The U.S. Department of Justice, twenty states, and the District of Columbia sued Microsoft in 1998 for anticompetitive practices, dragging Gates into one of the largest antitrust battles in American history.
- Rather than retreat, Gates pivoted — announcing in 2006 his intention to leave Microsoft and channeling his energy into humanitarian work through the Bill & Melinda Gates Foundation.
- The foundation has since distributed $54.8 billion across global health, vaccines, education, and climate, with Gates stepping down from Microsoft's board entirely in March 2020 to focus solely on this mission.
- With the COVID-19 pandemic, a $50 million Alzheimer's research commitment, and the Breakthrough Energy Coalition already in motion, Gates now operates at the intersection of the world's most urgent crises.
William Henry Gates III was born in Seattle in 1955 to a lawyer and a teacher. By thirteen he was programming computers; by twenty-five he had dropped out of Harvard and co-founded Microsoft with Paul Allen. By thirty-one, his fortune had reached $1.25 billion, making him the youngest billionaire in America.
Through the 1980s and 1990s, Gates built Microsoft into the world's largest software company. MS-DOS sold over 100 million copies by the early 1990s, Windows launched in 1985 to challenge Apple, and Gates held the top spot on Forbes's billionaires list for twelve consecutive years. But dominance invited scrutiny. In May 1998, the Department of Justice and twenty states sued Microsoft for anticompetitive practices. A settlement was approved in 2002, though critics argued the penalties were too lenient. Gates had already stepped down as CEO in January 2000.
Something deeper was shifting. In 2006, Gates announced he would leave his daily role at Microsoft by 2008 to pursue humanitarian work. He and his wife Melinda — married on January 1, 1994, and parents of three children — had already founded the Bill & Melinda Gates Foundation, which by 2019 had distributed $54.8 billion to causes spanning global health, vaccines, and education.
The foundation's ambitions kept expanding. A $33 million grant helped China fight tuberculosis. A $10 billion pledge in 2010 funded a decade of vaccine research. In 2015, Gates helped launch the Breakthrough Energy Coalition alongside Mark Zuckerberg and Jeff Bezos to mobilize capital for carbon-free energy. In 2017, he invested $50 million in Alzheimer's research — a signal that his philanthropic vision was reaching beyond infectious disease.
By March 2020, as COVID-19 reshaped the world, Gates resigned from the boards of both Microsoft and Berkshire Hathaway to dedicate himself entirely to his foundation. His net worth stood at $98 billion. The distance he had traveled — from self-taught teenage coder to one of history's most consequential philanthropists — was remarkable. What remained open was how his work would meet the converging crises of pandemic, climate, and inequality that now defined the era.
William Henry Gates III was born on October 28, 1955, in Seattle, Washington, to a lawyer father and a teacher mother. By thirteen, he was already programming computers. By twenty-five, he had co-founded Microsoft with Paul Allen after dropping out of Harvard. By thirty-one, he was the youngest billionaire in America, his fortune valued at $1.25 billion. By the time he turned fifty, he had reshaped global philanthropy itself.
The arc from software entrepreneur to world-class philanthropist did not happen overnight, but it was deliberate. Gates spent the 1980s and 1990s building Microsoft into the world's largest software company. He developed MS-DOS for IBM—a system that sold two million copies by 1984 and over 100 million by the early 1990s. He introduced Windows in 1985 to compete with Apple. He became the richest man on Earth, holding the top spot on Forbes's billionaires list for twelve consecutive years from 1995 to 2007. He also became the target of antitrust litigation. In May 1998, the U.S. Department of Justice, twenty states, and the District of Columbia sued Microsoft for illegal, anticompetitive practices. The case dragged on for years. A federal judge approved most of a settlement in November 2002, though nine states and D.C. argued the penalties were too lenient. Gates stepped down as CEO in January 2000, taking the title of Chief Software Architect instead.
But something was shifting. In June 2006, Gates announced he would step away from his daily duties at Microsoft beginning in July 2008 to focus on humanitarian and educational interests. Two years later, in June 2008, he made the transition official. He had already begun laying groundwork. In 1999, he and his wife Melinda—whom he married on January 1, 1994—had three children: Jennifer Katharine, Rory John, and Phoebe Adele. Together, they founded the Bill & Melinda Gates Foundation, which by 2019 had distributed $54.8 billion to charitable causes worldwide.
The foundation's reach expanded steadily. In April 2009, Gates announced a $33 million grant through the foundation to help China's Ministry of Health fight a tuberculosis epidemic. In January 2010, the foundation pledged $10 billion over the next decade for vaccine research—a commitment that would prove prescient. Gates also began investing in energy solutions. In November 2015, he helped launch the Breakthrough Energy Coalition during the United Nations climate conference, a private fund with more than twenty-eight investors including Facebook CEO Mark Zuckerberg and Amazon CEO Jeff Bezos, designed to mobilize capital for carbon-free energy alternatives.
In November 2017, Gates made his first major commitment to a non-communicable disease, investing $50 million in the Dementia Discovery Fund, a public-private partnership focused on Alzheimer's research. The move signaled an expansion of his philanthropic vision beyond infectious disease. By March 2020, as the COVID-19 pandemic began reshaping the world, Gates stepped down from the boards of Microsoft and Berkshire Hathaway to dedicate himself fully to his philanthropic priorities. His net worth at that moment stood at $98 billion, placing him second on the Forbes billionaires list.
Gates had traveled a remarkable distance from the teenager who taught himself to code in the 1960s. He had built one of history's most dominant technology companies, survived and emerged from one of the largest antitrust cases in American history, and then systematically redirected his wealth and influence toward global health, education, and climate. The question that remained was not whether he had the resources to shape the world—he clearly did—but how his foundation's work would unfold in an era of pandemic, climate crisis, and deepening inequality.

La Conversación del Hearth Otra perspectiva de la historia
What made Gates decide to leave Microsoft at the height of his power? He was still the richest man in the world.
He wasn't leaving power—he was redirecting it. By 2006, he'd already spent a decade watching the foundation grow. He had the resources to do something most people never can: step away from the thing that made him rich and focus entirely on what he believed mattered more.
But why philanthropy? Why not stay and run the company?
By 2000, Microsoft was already facing antitrust suits. The company was mature, profitable, defended. Gates had proven what he could do in software. The foundation gave him a different kind of challenge—one without a clear endpoint, one that required learning entirely new fields: global health, vaccines, education.
The timing is interesting. He steps down in 2008, right as the financial crisis hits.
Yes. And then in 2010, just as the world is recovering, he pledges $10 billion for vaccine research. He was positioning the foundation to move fast when the world needed it most.
Did he see the pandemic coming?
Not specifically. But he'd been studying infectious disease for years. He understood the risk. When COVID arrived, the foundation was already structured to respond.
What's the through-line from Microsoft to the Breakthrough Energy Coalition?
Control. Gates built Microsoft by controlling the operating system—the foundation that everything else runs on. With energy, he's trying to do the same thing: fund the foundational technologies that make everything else possible. Carbon-free energy is the operating system for a livable future.
