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 on 30 August 1978 in Liss, England, was cremated and his ashes taken to London.

Recognition
Shortly before his death, Zygalski was honored by the Polish University in Exile with an honorary doctorate for his role in breaking Enigma.
In 2009 the Polish Post issued a commemorative stamp featuring Henryk Zygalski alongside fellow cryptologists Marian Rejewski and Jerzy Różycki.[2]
In 2021 the Enigma Cipher Centre, an educational and scientific institution dedicated to the Polish mathematicians who broke the Enigma cipher, including Henryk Zygalski, opened in Poznań.[3]
