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.
Tre matematici polacchi risolvono l'Enigma. Nel settembre 1932 l'ufficio cifra polacco chiamò tre matematici, Marian Rejewski, Henryk Zygalski e Jerzy Rozicki, con il compito di cercare di forzare la macchina Enigma usata dai tedeschi e da questi ultimi considerata inattaccabile.
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.
2014 Hall of Honor Inductee. 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.
