Colossus computer/Inventors
After three months of experimentation and improvement, Robinson could analyze no more than two or three Tunny messages a week. A faster and more reliable machine was needed. Engineer Tommy Flowers, head of the Switching Group at Dollis Hill, invented Colossus.
Why was the Colossus computer destroyed?
After the war the British codebreakers found out that the code machine was the Lorenz SZ42. All the secret Colossus computers were taken to pieces, so that no one would find out about them. The designs were destroyed. For thirty years no one knew who made them.
How did the Colossus computer work?
Running Colossus The Colossus machine was driven by the tape reader which scanned punch holes in a tape representing the cipher text of a message. The punch holes were converted by a photoelectric reader into a sequence of pulses which were then sent to the arithmetic and logic circuits of Colossus for processing.
What happened to the Colossus computer after the war?
After the war all Colossi were dismantled. Immediately after WWII, most Colossus computers were ordered to be demolished. They were either destroyed or dismantled and the components were reused. Two machines were kept for future use by GCHQ during the Cold War.
Why was Colossus kept secret?
News of the existence of the Colossus, widely regarded as the first electronic computer, was kept top secret for 30 years partly because of the sophistication of its methods to help break Lorenz messages by finding the frequently changing wheel patterns of the Lorenz encryption machine.
