Caption reads: IEEE MILESTONE: Manchester University "Baby" Computer and its Derivatives, 1948-1951. At this site on 21 June 1948 the "Baby" became the first computer to execute a program stored in addressable read-write electronic memory. "Baby" validated Williams-Kilburn Tube random-access memories, later widely used, and led to the 1949
