Yes, Paul Allen and Bill Gates attended the same high school. They both went to Lakeside School, a private preparatory school in Seattle, Washington. They met there when Allen was in his teens and Gates was a couple of years younger. Their shared passion for computers led them to become friends and eventually co-found Microsoft.
