The Cambridge EDSAC was the world's second operational stored program computer and the first to be truly usable for large-scale operations. It was constructed at the University's Mathematical Laboratory (now the Computer Laboratory) by Maurice Wilkes, who was inspired by John von Neumann's account of the EDVAC, and ran its first program on 6 May 1949.
