About Ludomir Danilewicz
Lived 1904 – 1971 (aged 66). Ludomir Danilewicz was a Polish engineer.
Beginning in 1933, after the Cipher Bureau's mathematician-cryptologist Marian Rejewski reconstructed the German military Enigma rotor cipher machine, AVA built Enigma "doubles" as well as all the electro-mechanical equipment subsequently designed at the Cipher Bureau to expedite routine breaking and reading of Enigma ciphers.
AVA's other directors were Edward Fokczyński, Antoni Palluth, and Ludomir Danilewicz's younger brother, Leonard Danilewicz. The company took its name from the combined radio callsigns of the Danilewicz brothers (TPAV) and Palluth (TPVA). When the company was being formed about 1929, the Danilewicz brothers were short-wave "hams" and students at the Warsaw Polytechnic.
