In 1943 J. Presper Eckert and John Mauchly began construction of the 'Electronic Numerical Integrator And Computer'. It was used to calculate ballistic firing tables during World War II. Apr 04 00, 12:34 AM

Although many people think the American 'ENIAC' was the first programmable, electronic computer (operational in 1947), it actually was the British 'Colossus' (operational in early 1944). A brilliant young telephone engineer at the Post Office Research Station in London named Tommy Flowers designed an electronic computer named Colossus to aid in the decoding effort of German radio messages in World War II coded on the Enigma machine. Colossus used 1,500 valves (vacuum tubes) and an optical paper tape reader operating at a read speed of 5,000 characters a second (which was about 30 miles an hour) and began operating five months before D-Day. A total of 10 Colossus computers were built, the design being improved and upgraded throughout the rest of the war. The Ultra project was kept secret until the mid-1970s, when the 30-year rule allowed its release. This secrecy is why many people think the American ENIAC was the first programmable, electronic computer. Although all 10 Colossus computers and all the technical drawings and diagrams for them were ordered by Winston Churchill to be destroyed at the end of the war to prevent them from falling into the hands of the Russians during the Cold War, only eight of the 10 Colossus machines were destroyed immediately at the end of the war. The remaining two were moved to British secret service headquarters, where they may have played a significant part in the codebreaking operations during the Cold War. In 1960, the order finally came to destroy the last two Colossus machines. One has been rebuilt from photographs, memories of the former staff, and scraps of schematics (kept illegally!) and is currently located at Bletchley Park. To learn more about this rebuild, search for 'Tony Sale' Colossus. Dec 30 02, 3:24 PM
