Konrad ZuseDied 18 Dec 1995 at age 85 (born 22 Jun 1910).German engineer who in 1941 constructed the first fully operational program-controlled electromechanical binary calculating machine, or digital computer, called the Z3. Earlier, Zuse developed and built the Z1 the first binary digital computer in the world (1936-8) and two more machines before the end of WW II, but he was unable to convince the Nazi government to support his work. He created a basic programming system known as Plankalkül with which he designed a chess playing program.The Z3 was destroyed in 1944 during the war. Next came the more sophisticated Z4, which was the only Zuse Z-machine to survive the war, by several moves to new locations away from air raids. During the last days of war it was hidden. In 1950, he took it to Zurich. |
