The breaking of the Enigma in World War II and in the years before is one of the most fascinating chapters in crypto history. It all began when in 1929 the three mathematics students Marian Rejewski, Henryk Zygalski, and Jerzy Różycki from the University of Poznań, Poland, were hired as codebreakers. Later, they managed to break the Enigma. Today, Rejewski, Zygalski, and Różycki are national heroes in Poland. Especially in Poznań, where they went to university, they are highly regarded.
