Alan Turing was a great man. He was a coder during the World War II. He was the hero who cracked the German's code with his computer he made.
Here is a picture of Alan aged only 16:
The German's had a machine called the Enigma machine that could send messages in a different form. For example if someone typed in the letter 'G' it might
have come up as the letter 'B'.
Here is a picture of an Enigma machine:
This is the machine that Alan Turing used to break the Enigma code. This specific machine is the rebuild of the bombe(Bombe-Rebuild). The Bombe Rebuild could
calculate 15 operations a second.
Here is a picture of the Bombe-Rebuild:
Now that Britain could hear the German's code, the war was easier and they could now intercept the German's attack. So then Germany's leader, Hitler, commited suicide and Germany was a mess. After that the war was over and the world was calm again.
