Bill Gates — The Man Who Helped Put a Computer on Every Desk

Bill Gates is an American technologist, entrepreneur, and philanthropist who co-founded Microsoft, the world's largest personal-computer software company. He is one of the central figures of the personal-computing revolution and, in his later career, one of the most significant philanthropists in modern history.

Born in Seattle in 1955, Gates developed an early passion for computers, befriending his future business partner Paul Allen at school. He dropped out of Harvard in 1975 to co-found Microsoft, which he led for decades as it became a dominant force in software.

In his second act, Gates turned his focus to philanthropy through the Bill & Melinda Gates Foundation, committing to give away the vast majority of his wealth to global health, development, and other causes.

This timeline traces his journey from a young programmer to a technology titan and global philanthropist, with major dates and facts cross-checked against authoritative sources. Some financial figures fluctuate over time.

Bill Gates's legacy is twofold: he helped lead the personal-computing revolution that transformed modern life, and he became one of history's most significant philanthropists. Through Microsoft, he helped make computing accessible worldwide, and through his foundation, he has directed vast resources toward global health and development, setting a model for large-scale giving.

Gates's influence spans technology, business, and philanthropy. His work at Microsoft shaped the software industry and the spread of personal computers. His philanthropic model, including the Giving Pledge, has influenced how wealthy individuals approach charitable giving, and his foundation has had a major impact on global health initiatives.

Technologist vs. philanthropist: Gates first led the PC revolution, then became a leading global philanthropist. Microsoft vs. Gates Foundation: One transformed computing; the other targets global health and development. Early Gates vs. later Gates: The young programmer became a technology titan and then a full-time philanthropist. Gates vs. other tech founders: He is often cited alongside peers for pioneering personal computing and for large-scale giving.

Bill Gates's impact spans the digital and philanthropic worlds. By helping make computing accessible, he changed how people work, learn, and communicate. Through his foundation and the Giving Pledge, he has reshaped modern philanthropy and directed enormous resources toward global health and development challenges.

SHORT SUMMARY: Bill Gates (born 1955) co-founded Microsoft in 1975 with Paul Allen, led the personal-computing revolution, and became one of the world's leading philanthropists through the Bill & Melinda Gates Foundation.

MEDIUM SUMMARY: Born in Seattle in 1955, Gates discovered computing at the Lakeside School, where he met Paul Allen. He dropped out of Harvard in 1975 to co-found Microsoft, which became the world's largest PC software company and was incorporated in 1981. He served as CEO for about 25 years before handing the role to Steve Ballmer in 2000 and becoming chief software architect until 2008. That same year, 2000, he established the Gates Foundation. He co-founded the Giving Pledge in 2010, stepped down as chairman in 2014, and left the board in 2020, dedicating himself to philanthropy focused on global health, development, and climate.

LONG SUMMARY: William Henry Gates III, born October 28, 1955 in Seattle, Washington, is one of the central figures of the technology age and one of the most significant philanthropists in modern history. The son of attorney William H. Gates Sr. and civic leader Mary Gates, he developed a passion for computing at the private Lakeside School, where he befriended his future business partner Paul Allen. In 1973 he enrolled at Harvard University but dropped out in 1975 to co-found Microsoft with Allen, aiming to capitalize on the emerging personal-computer revolution. Microsoft was incorporated in 1981 and grew into the world's largest PC software company under his leadership. Gates served as CEO for about 25 years before being succeeded by Steve Ballmer in 2000, after which he became chief software architect until 2008. In 2000 he and Melinda established the Bill & Melinda Gates Foundation, and in 2010 he, Melinda, and Warren Buffett founded the Giving Pledge to encourage the wealthy to give away most of their fortunes. He stepped down as Microsoft's chairman in 2014 and resigned from its board in 2020. Following his 2021 divorce, he has focused fully on philanthropy — targeting global health, development, and climate — pledging to give away nearly all of his wealth, and stating that the foundation will eventually wind down. Note that financial figures such as net worth and donation totals fluctuate over time.
