• In 1896, the first U.S. patent for an addressing machine, the Addressograph was issued to Joseph Smith Duncan of Sioux City, Iowa.
  • It was a development of the invention he had made in 1892. His earlier model consisted of a hexagonal wood block.
  • Onto which he glued rubber type which had been torn from rubber stamps.
  • While revolving, the block simultaneously inked the next name and address ready for the next impression.
  • The original company which manufactured the Addressograph, Addressograph International, merged in 1932 with American Multigraph of Cleveland.
  • In 1978 the corporate headquarters moved from Cleveland to Los Angeles, California, and the corporation name changed in 1979 to AM International.
