Life
Zygalski was, from September 1932, a civilian cryptologist with the Polish General Staff's Biuro Szyfrów (Cipher Bureau), housed in the Saxon Palace in Warsaw. He worked there with fellow Poznań University alumni and Cipher Bureau cryptology-course graduates Marian Rejewski and Jerzy Różycki. Together they developed methods and equipment for breaking Enigma messages.
In late 1938, in response to growing complexities in German encryption procedures, Zygalski designed the "perforated sheets," also known as "Zygalski sheets," a manual device for finding Enigma settings. This scheme, like the earlier "card catalog," was independent of the number of connections being used in the Enigma's plugboard, or commutator.
After the war he remained in exile in the United Kingdom and worked, until his retirement, as a lecturer in mathematical statistics at the University of Surrey. During this period he was prevented by the Official Secrets Act from speaking of his achievements in cryptology.
He died August 30, 1978, at Liss, was cremated and his ashes taken to London.

Famous quotes containing the word life:
“For all the boredom the straight life brings, it’s not too bad.”
—Gus Van Sant, U.S. screenwriter and director, and Dan Yost. Bob Hughes (Matt Dillon)
“I hid my love when young till I
Couldn’t bear the buzzing of a fly;
I hid my life to my despite
Till I could not bear to look at light:
I dare not gaze upon her face
But left her memory in each place;
Where’er I saw a wild flower lie
I kissed and bade my love good-bye.”
—John Clare (1793–1864)
“One reason writers write is out of revenge. Life hurts; certain ideas and experiences hurt; one wants to clarify, to set out illuminations, to replay the old bad scenes and get the Treppenworte said—the words one didn’t have the strength or ripeness to say when those words were necessary for one’s dignity or survival.”
—Cynthia Ozick (b. 1928)
