# Electronic Delay Storage Automatic Calculator

**Electronic Delay Storage Automatic Calculator** (**EDSAC**) was an early British computer. It was made by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England. EDSAC was the first stored-program electronic computer. It was also the first to run a computer game.

Later the project was supported by J. Lyons & Co. Ltd., a British company. They were rewarded with the first commercial computer, LEO I. LEO I was based on the EDSAC design. EDSAC ran its first programs on 6 May 1949, when it calculated a table of square numbers^{[1]} and a list of prime numbers.
