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.
Cyclone (computer) The Cyclone, was a vacuum tube computer, built by Iowa State College (later University) at Ames, Iowa. The machine was placed into operation in July 1959. It was based on the IAS architecture developed by John von Neumann. The prototype of this machine is ILLIAC, the University of Illinois Digital Computer. The Cyclone used 40-bit words, used two 20-bit instructions per word, and each instruction had an eight-bit op-code and a 12-bit operand or address field. In general IAS-based computers were not code compatible with each other, although originally math routines which ran on the ILLIAC would also run on the Cyclone.
