Allen was born on January 21, 1953, in Seattle, Washington, to Kenneth Sam Allen and Edna Faye (née Gardner) Allen. Allen attended Lakeside School, a private school in Seattle, where he befriended the two-years-younger Bill Gates, with whom he shared an enthusiasm for computers. They used Lakeside's Teletype terminal to develop their programming skills on several time-sharing computer systems. They also used the laboratory of the Computer Science Department of the University of Washington, doing personal research and computer programming; on at least one occasion in 1971 they were banned from the laboratory for abuse of their privileges there. According to Allen, in their teenage years he and Bill Gates would go dumpster-diving for computer program code. After graduating and obtaining a perfect SAT score of 1600, Allen went to Washington State University, where he joined Phi Kappa Theta fraternity. He dropped out after two years to work as a programmer for Honeywell in Boston, near Harvard University where Bill Gates had ended up. Allen later convinced Gates to drop out of Harvard in order to create Microsoft.
