Technology

The Manchester Mark I computer executes its first program successfully June 21 (see ENIAC, 1946). Designed by graduate student Tom Kilborn, 26, and electrical engineering professor Frederic C. (Calland) Williams, 37, at Britain's University of Manchester, it is the first stored-program digital computer, and its cathode ray tube has a true random access memory, albeit limited (see BINAC, Forrester, 1949).
