Born on January 21, 1953, in Seattle, Washington, Paul Allen met fellow Lakeside School student and computer enthusiast Bill Gates when Allen was 14 and Gates was 12. Less than a decade later, in 1975, college drop-outs Allen and Gates founded Microsoft. Allen resigned after being diagnosed with Hodgkin's disease in 1983 and continued to pursue other business, research and philanthropic opportunities. As Microsoft grew and its stock steadily rose, Allen's share in the company he co-founded made him a billionaire at just over 30 years of age. In 1983, Allen, known as the "idea man" counterpart to Gates' "man of action," resigned from Microsoft after being diagnosed with Hodgkin's disease. After undergoing several months of radiation treatment, his health was restored. Post Microsoft, Allen began to concentrate on other projects, hoping to find the next big idea lurking somewhere just out of sight. In 1986, he set up a company called Vulcan Ventures to research possible investments; to that end, he founded a Silicon Valley think tank in 1992 called Interval Research. Through Interval Research and Vulcan Ventures, Allen began to put his long-term dream of a wired world society — in which virtually everyone is online — into practice.
