Bill Gates
Co-founder 1975Background
Bill Gates grew up in Seattle and began programming as a teenager at Lakeside School, where he met Paul Allen. Before Microsoft, he wrote code for school scheduling projects, worked with Allen on Traf-O-Data, and entered Harvard with a reputation for unusual programming intensity. Gates was not merely a technical founder; he was the commercial architect of Microsoft's earliest strategy. When Allen saw the Altair 8800 opportunity in 1975, Gates helped turn a speculative idea into a working BASIC interpreter and then into a business. His background combined mathematics, programming discipline, legal caution, and competitive instinct. That mix shaped Microsoft's emphasis on licensing, contracts, platform control, and developer tools. Gates left Harvard to focus on Microsoft because he believed the software layer around personal computers could scale faster than hardware manufacturing. His early experience also made him unusually sensitive to piracy and intellectual property, which explains his famous 1976 letter arguing that software creators needed to be paid.
Role at Microsoft Corporation
Microsoft possesses arguably the most iconic, foundational founding story of the entire personal computing revolution, rooted in the intense, brilliant partnership of two teenage computer prodigies who recognized the software potential of the microcomputer before anyone else. The company was founded in 1975 in Albuquerque, New Mexico, by Bill Gates and Paul Allen. The two brilliant, obsessed childhood friends from Seattle had famously spent their teenage years hacking into corporate mainframe computers simply to score free expensive computing time. Their world-changing 'eureka' moment occurred in January 1975 when Paul Allen saw an obscure magazine cover (Popular Electronics) featuring the Altair 8800 (the world's very first commercially viable microcomputer). Allen excitedly showed it to Gates. They immediately realized a fundamental truth: this tiny, primitive computer was useless because it lacked a functional programming language. In a legendary feat of engineering brilliance, Gates and Allen wrote a version of the BASIC programming language for the Altair in just a few weeks, without ever physically touching the actual machine (using a complex emulator). They founded 'Micro-Soft' to sell the software. However, their masterstroke occurred in 1980. When IBM desperately needed an operating system for its secretive new Personal Computer, Gates bought a rudimentary operating system (QDOS) for $50,000, slightly modified it into MS-DOS, and licensed it to IBM. By retaining the right to license MS-DOS to *other* computer manufacturers, Bill Gates established the foundational architecture of the immensely powerful software monopoly that dominated the 20th century.
