Study Notes
Enigma Code Breaking
- Germany used the Enigma machine for military code in the 1920s and 1940s
- British codebreakers at Bletchley Park cracked 3,000 German military messages daily
- The Enigma device had 150 quintillion possible combinations
- A team of mathematicians and codebreakers in Britain developed and began using the Bombe machines to crack Enigma code in 1940
- The Bombe machines worked around the clock (day and night) at Bletchley Park to crack the code
- Alan Turing helped develop the Bombe machines. He also realised that to find all the possible combinations of the Enigma machine's code, a computer capable of replicating 60 Enigma machines was required. To achieve this, he and Gordon Welchman increased the power of the "Bombe," a computer developed earlier by Polish cryptographers in 1938
- Turing also recognised early potential of digital computing during the WWII era and immediately saw the potential programmable computing machines
- Colossus code-breaking machines, the first programmable digital electronic computers, were developed in 1944 at Bletchley Park.
Digital Computing
- Alan Turing realised the need for a computer to break the Enigma codes. He and Gordon Welchman worked to increase the power of the Bombe machine which helped to crack Enigma military messages.
- The very first programmable digital electronic computers, the Colossus machines, were created at Bletchley Park in 1944
