The Electronic Delay Storage Automatic Calculator (EDSAC) was an early British computer.[1] Inspired by John von Neumann's seminal First Draft of a Report on the EDVAC, the machine was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England. EDSAC was the second electronic digital stored-program computer to go into regular service.[2]
Later the project was supported by J. Lyons & Co. Ltd., intending to develop a commercially applied computer and succeeding in Lyons' development of LEO I, based on the EDSAC design. Work on EDSAC started during 1947,[3] and it ran its first programs on 6 May 1949, when it calculated a table of square numbers[4] and a list of prime numbers.[5][6] EDSAC was finally shut down on 11 July 1958, having been superseded by EDSAC 2, which remained in use until 1965.[7]
