Invented by John G. Kemeny and Thomas E. Kurtz of Dartmouth College in Hanover, New Hampshire, BASIC was first successfully used to run programs on the school’s General Electric computer system 50 years ago this week–at 4 a.m. on May 1, 1964, to be precise.

The two math professors deeply believed that computer literacy would be essential in the years to come, and designed the language–its name stood for “Beginner’s All-Purpose Symbolic Instruction Code”–to be as approachable as possible. It worked: at first at Dartmouth, then at other schools.
