Bill Gates

Biography

William Henry Gates III was born October 28, 1955 in Seattle into a family of lawyers and bankers. His mother sat on the board of United Way alongside IBM executives — a connection that would later prove fateful. At 13, Gates and Paul Allen discovered the school's Teletype Model 33 terminal and became obsessed with computing. They founded Traf-O-Data at 15, selling traffic analysis to local governments — Gates's first business. He enrolled at Harvard in 1973, spent more time in the computer lab than class, and dropped out in 1975 to co-found Microsoft with Allen in Albuquerque, New Mexico.

The pivotal moment came in 1980 when IBM, building its first PC, needed an operating system. Gates did not have one. He bought 86-DOS from Seattle Computer Products for $50,000 — a sum that would have seemed enormous at the time — and licensed it to IBM as PC-DOS while retaining the right to license it to others as MS-DOS. That decision to keep the rights was the most consequential business decision of the personal computer era. Every PC clone ran MS-DOS. Microsoft collected a royalty from every one.

Windows followed, then Office, then Internet Explorer, then Windows Server, then Xbox. At Microsoft's peak in 2000, Gates was the richest person in the world at $100B. He stepped down as CEO in 2000 but remained chairman until 2014. In parallel, the Bill & Melinda Gates Foundation became the largest private philanthropic organization in history, committing over $50B to global health, education, and poverty alleviation.

Core Philosophy

Software is leverage. Gates understood before almost anyone that software — not hardware — was the moat. One copy of MS-DOS licensed to IBM was replicated across millions of PCs. The economics were unlike anything in manufacturing history: near-zero marginal cost, infinite scalability, and network effects that locked in customers. He protected that leverage ferociously, sometimes to the point of antitrust action.

Learn from your unhappy customers. Gates institutionalized the practice of reading customer feedback personally — a habit he called "Think Weeks," during which he isolated himself and read papers, technical reports, and customer letters. His famous 1995 "Internet Tidal Wave" memo — which pivoted the entire company toward the web — emerged from one of these sessions.

Aggressive philanthropy. Gates and Warren Buffett co-founded the Giving Pledge in 2010, committing themselves and enlisting 200+ billionaires to give the majority of their wealth to philanthropy. Gates's Gates Foundation has contributed to near-eradication of polio, saved millions from malaria with bed-net distribution, and seeded 30+ years of global health infrastructure.
