The Manchester Baby was the world's first stored-program computer. It was built at the Victoria University of Manchester by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948. It was designed as a testbed for the Williams tube, the first random-access digital storage device. Although the computer was considered "small and primitive" by the standards of its time, it was the first working machine to contain all of the elements essential to a modern electronic computer.
Philip was introduced to the House of Lords on 21 July 1948, immediately before his uncle Louis Mountbatten, who had been made Earl Mountbatten of Burma. Philip, like his sons Charles and Andrew and other royals (with the exception of the 1st Earl of Snowdon), ceased to be members of the House of Lords following the House of Lords Act 1999. He never spoke in the House.
