  Henryk Zygalski
Henryk Zygalski was a Polish mathematician and cryptologist.
A student of the Mathematical Institute at the University in Poznan, he was given in 1929, along with twenty-odd of his fellow-students, a rudimentary training in codebreaking during a special course, organized by the military.
It was located in a vault in the Army's regional command post in the outskirts of Poznan - a building built by Kaiser Wilhelm II as the official residence for the Crown Prince.

It included Jerzy Rozycki, Henryk Zygalski and Marian Rejewski (all of whom were products of the notable flowering of Polish mathematics in the 1920s and 1930s).
Zygalski realised that whether this occurred or not depended on the wheel order and the start position, therefore inversely if it did occur it implied one of a set of possible Enigma configurations.
Zygalski realised that the analysis of the vast amount of information required could be achieved by a grill method using perforated sheets.

 Historical Background
At the Biuro Szyfrow, three brilliant cryptanalysts, Marian Rejewski, Henryk Zygalski and Jerzy Rozicki, succeeded in breaking the Enigma in 1933.
Zygalski invented a cryptanalytical method using perforated sheets which exploited the German procedural error of repeating the encipherment of the message-setting.
In fact this is precisely what occurred in May 1940 after which the Polish bomby and the perforated Zygalski sheets were suddenly rendered useless.

 Legal Tyranny - The Story Behind U571 - Chapter 7, The Code is Broken (Temporarily)
For one weekend, Polish code breakers had an opportunity to thoroughly study an Enigma machine - before it was carefully repackaged for Monday morning pickup.
As a result of this examination, three Polish mathematicians (Marian Rejewski, Jerzy Rozycki, and Henryk Zygalski) discovered that the Enigma's keyboard was wired in alphabetical order, not keyboard order.
With that discovery in hand, they created a decoder machine, called, La Bomba (because it was cylindrical, like a bomb) which helped the Poles trace Nazi naval, air and land movements.

By 1928 Germany had made their Enigma machine more sophisticated such that frequency counts were futile.
By 1932, after the Poles attempted to work on a commercial Enigma machine and failed, their cipher bureau, the Biuro Szyfrow, acquired many mathematicians, among them were Marian Rejewski, Jerzy Rozycki and Henryk Zygalski.
Up until the Enigma era, it was thought that the best cryptanalysts were linguists but surely and quickly mathematicians took over as the primary role of cryptanalysts, because of the electromechanical nature of Enigma.

 Perforated sheets - Wikipedia, the free encyclopedia (via CobWeb/3.1 planetlab2.netlab.uky.edu)   (Site not responding. Last check: 2007-11-02)
The "perforated sheets" were invented about October 1938 by Polish Cipher Bureau cryptologist Henryk Zygalski, and accordingly are sometimes known as Zygalski sheets.
The Cipher Bureau's manual manufacture of the sheets, which was done by the mathematician-cryptologists themselves, was very time-consuming; by December 15, 1938, only one-third of the job had been completed.
In late July 1939, a month before the outbreak of World War II, the Polish General Staff's Cipher Bureau disclosed to their French and British allies, at Warsaw, their cryptologic achievements in breaking Enigma ciphers.
