His parents enrolled him at the Lakeside School, a rigorous Seattle private high school that future Microsoft cofounder Paul Allen also attended. Gates often credits his discovery of computers to the tools he gained at Lakeside. "The experience and insight Paul Allen and I gained here gave us the confidence to start a company based on this wild idea that nobody else agreed with—that computer chips were going to become so powerful that computers and software would become a tool that would be on every desk and in every home," he said in a 2005 speech at the school.

After graduating from Lakeside in 1973, Gates headed to Harvard. Though he entered as a pre-law major, he soon changed course and quickly worked his way through the university's upper-level math and computer science classes.

Two years later, Gates dropped out of school to found Microsoft with Paul Allen. Though he never earned his bachelor's degree, Harvard awarded him an honorary doctorate in 2007. "I'm a bad influence. That's why I was invited to speak at your graduation," he said at the commencement ceremony. "If I had spoken at your orientation, fewer of you might be here today."
