Bill Gates: The Early Years Geniuses at Work
Gates watches his friend and future Microsoft co-founder Paul Allen typing on a teletype terminal at the Lakeside School in Seattle in 1968. Gates was 13 when he entered the exclusive prep school, which was around the time this photo was taken.
Much of the computer equipment at Lakeside was bought with proceeds from a rummage sale organized by the students' mothers. Gates was drawn to programming the machines and was excused from math classes to pursue his interest.
