Marian Adam Rejewski (Polish: [ˈmarjan rɛˈjɛfskʲi] ⓘ; 16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist who in late 1932 reconstructed the sight-unseen German military Enigma cipher machine, aided by limited documents obtained by French military intelligence.
The key observation of Marian Rejewski, often called Rejewski's Theorem - the trick that made things work for him - is a fact about the product of two reflector permutations. Roughly speaking, the cyclic expression of the product of two reflectors has cycles that come in pairs, each cycle in a pair being of the same length.
Marian Rejewski was responsible for the initial analysis that enabled exploitation of the German ENIGMA cryptographic machine. Without his breakthroughs, which he provided to the French and British in 1939, the U.K. and U.S. may have never been able to exploit ENIGMA.
Marian Adam Rejewski (ur. 16 sierpnia 1905 w Bydgoszczy, zm. 13 lutego 1980 w Warszawie) – polski matematyk i kryptolog, który w 1932 roku złamał szyfr Enigmy, najważniejszej maszyny szyfrującej używanej przez hitlerowskie Niemcy, porucznik Armii Polskiej w Wielkiej Brytanii.

Marian Adam Rejewski ( [ˈmarjan reˈjefski] ; 16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist who in 1932 solved the plugboard-equipped Enigma machine, the main cipher device used by Germany.
Aug 14, 2019 · It was the work of those three Polish students, Marian Rejewski, Henryk Zygalski and Jerzy Rozycki, that set Alan Turing on the way to breaking the German codes when he arrived at the Government Code and Cypher School at Bletchley Park on 4 September 1939, the day after war broke out.

The bomba, or bomba kryptologiczna (Polish for "bomb" or "cryptologic bomb"), was a special-purpose machine designed around October 1938 by Polish Cipher Bureau cryptologist Marian Rejewski to break German Enigma-machine ciphers.
The most promising person found was Marian Rejewski – a well-trained mathematician who studied at University in Poznań but also had a one-year scholarship in Gottingen in his resume (he spoke impeccable German). The two others selected were Henryk Zygalski and Jerzy Różycki - also graduates of the Mathematical Institute at University in Poznań.
They were Marian Rejewski, Jerzy Różycki and Henryk Zygalski, and their contribution would prove invaluable in the coming years. But for all their brilliance, they would need a little help from their friends.

Marian Adam Rejewski (Polish: [ˈmarjan rɛˈjɛfskʲi] ; 16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist. In 1932, he helped create the Enigma cipher machine. His invention helped Britain to begin reading German Enigma-encrypted messages.
In 1932–33 Polish mathematician Marian Rejewski deduced the wiring pattern inside the wheels of Enigma, assisted by Enigma operating manuals provided by the French secret service, to make a successful decryption machine.
