In the early days of World War II, the British government was desperate to read the encrypted messages of the German army. The Germans were using a code called Enigma, which had been invented by a German engineer named Arthur Scherbius in 1918.
The British government enlisted the help of a Polish mathematician named Marian Rejewski. Rejewski had been working on the Enigma problem since the early 1930s. In 1932, he and two of his colleagues, Jerzy Różycki and Henryk Zygalski, came up with a way to break the code.
Rejewski and his colleagues didn«t have a working Enigma machine, so they had to figure out the code by hand. They did this by studying the patterns of letters that appeared in the encrypted messages.
In 1936, the Germans made some changes to the Enigma machine, which made it harder to break the code. But Rejewski and his colleagues were able to keep up with the changes.
In 1939, the Germans invaded Poland. Rejewski and his colleagues fled to France, and then to Britain.
By the time the Germans invaded France in 1940, the British had managed to build their own Enigma machine. This machine was based on the work of Rejewski and his colleagues.
The British code-breakers, including Rejewski, were put to work breaking the German Enigma messages. They were able to read many of the messages, which gave them valuable information about the German army»s plans.
The work of Rejewski and his colleagues was a major factor in the Allied victory in World War II.
