Colossus At 70: The Computer That Helped Bring Down Hitler -- The Telegraph
Today marks the seventieth anniversary of Colossus, the world's first electronic computer.
War veterans and their families are gathering at Bletchley Park today to celebrate the seventieth anniversary of Colossus, the world's first electronic computer.
Designed by British telephone engineer Tommy Flowers, Colossus was built to speed up code-breaking of the complex Lorenz cipher, used in communications between Hitler and his generals during World War II.
