Entrepreneur and investor. Born in 1954, in Seattle, Washington. While attending the Lakeside School outside Seattle, 14-year-old Paul Allen met 12-year-old Bill Gates, a fellow student and computer enthusiast. Less than a decade later, in June 1975, Allen and Gates, both college dropouts; Allen from Washington State University founded Microsoft with the intention of designing software for the new wave of personal computers. By the time Allen arranged for Microsoft to buy an operating system called Q-DOS for $50,000, the company had already supplied software for emerging companies such as Apple and Commodore. Gates and Allen reinvented Q-DOS as MS-DOS and installed it as the operating system for IBM' PC offering, which dominated the market after its release in 1981.
