Computer History: Dr. Konrad Zuse and the Z3 Computer (Germany 1935-1945)

Computer History: Dr. Konrad Zuse, Germany: An excerpt from "The Machine that Changed the World," highlighting the pioneering work of Konrad Zuse, German computer scientist, engineer, and inventor, designed and constructed several early computers in his parents’ living room from 1935 through 1941, including the Z3, the first working programmable, fully automatic digital computer. The Z3 used 2,300 relays, performed floating point binary arithmetic and, used punched movie film for input. The German Aircraft Bureau purchased a Z3 for aerodynamic calculations. In 1945, the Z1, Z2 and Z3 machines were destroyed in an Allied bombing attack on Berlin. Zuse was able to save his Z4 machine by moving it to a small village in the Bavarian Alps, where it remained until he brought it to the Federal Technical Institute in Zürich, Switzerland in 1950. A reconstructed computer exists today at the Deutsches Museum.
