X-WR-CALDESC:10 February 1952: Edward Hebern\, who developed an electric co
 ding and decoding machine\, died. \n\nThe Hebern machine frequently attrac
 ts attention at the Museum. Hebern's invention were the first to embody th
 e wired rotor principle of encipherment. His first rotor machine\, picture
 d here\, was made of solid brass and employed a single rotor that worked i
 n conjunction with an electric typewriter. The machine was made before 192
 0 in Hebern's machine shop in Oakland\, CA.\n\nA bit of trivia for you - g
 uess where Mr. Hebern was when he came up with the idea of his electric ro
 tor machine......according to folkore\, he was in prison for horse thiever
 y! \n\nThe National Cryptologic Museum has two very rare five-rotor Hebern
  cipher machines in its collection. The Hebern Electric Company built what
  is acknowledged to be the first five-rotor cipher machine in the 1920's (
 a number of others were designed independently about the same time). Altho
 ugh this machine was never widely manufactured or used\, it is cryptologic
 ally significant as part of the overall evolution in U.S. manufactured rot
 or devices. We believe these two five-rotor machines are the only two that
  have survived. Financial assistance to acquire the Heberns came from an a
 nonymous donor.\n\n
