The coding machines Eva Salier worked on during the Holocaust were invented by whom?
Enigma machine The Enigma machines were a series of electro-mechanical rotor cipher machines developed and used in the early- to mid-20th century to protect commercial, diplomatic and military communication. Enigma was invented by the German engineer Arthur Scherbius at the end of World War I. Early models were used commercially from the early 1920s, and adopted by military and government services of several countries, most notably Nazi Germany before and during World War II. Several different Enigma models were produced, but the German military models, having a plugboard, were the most complex. Japanese and Italian models were also in use.
Yva Yva (1900–1942/44) was the professional pseudonym of Else Ernestine Neuländer-Simon who was a German Jewish photographer renowned for her dreamlike, multiple exposed images. As one of the first photographers who recognized the commercial potential of photography, she became a leading photographer in Berlin during the Weimar Republic. When the Nazi Party came to power, she was forced into working as a radiographer. She was deported by the Gestapo in 1942 and murdered, probably in the Majdanek concentration camp during World War II.
