The Teletype Corporation, a part of American Telephone and Telegraph Company's Western Electric manufacturing arm since 1930, came into being in 1928 when the Morkrum-Kleinschmidt Company changed its name to the name of its trademark equipment. Teletype Corporation, of Skokie, Illinois, was responsible for the research, development and manufacture of data and record communications equipment, but it is primarily remembered for the manufacture of electromechanical teleprinters.
Because of the nature of its business, as stated in the corporate charter, Teletype Corporation was allowed a unique mode of operation within Western Electric. It was organized as a separate entity, and contained all the elements necessary for a separate corporation. Teletype's charter permitted the sale of equipment to customers outside the AT&T Bell System, which explained their need for a separate sales force. The primary customer outside of the Bell System was the United States Government.
The Teletype Corporation continued in this manner until January 8, 1982, the date of settlement of United States v. AT&T, a 1974 United States Department of Justice antitrust suit against AT&T. At that time, Western Electric was fully absorbed into AT&T as AT&T Technologies, and the Teletype Corporation became AT&T Teletype. The last vestiges of what had been the Teletype Corporation ceased in 1990, bringing to a close the dedicated teleprinter business. One of the three Teletype manufacturing buildings in Skokie remains in use as a parking garage for a shopping center. Every other floor of the building has been removed. The other two buildings were demolished.
The Teletype Corporation had its roots in the Morkrum Company. In 1902, electrical engineer Frank Pearne approached Joy Morton, head of Morton Salt, seeking a sponsor for Pearne's research into the practicalities of developing a printing telegraph system. Joy Morton needed to determine whether this was worthwhile and so consulted mechanical engineer Charles Krum, who was vice president of the Western Cold Storage Company, which was run by Morton’s brother Mark Morton. Krum was interested in helping Pearne, so space was set up in a laboratory in the attic of Western Cold Storage. Frank Pearne lost interest in the project after a year, and left to get involved in teaching. Krum was prepared to continue Pearne’s work, and in August 1903 a patent was filed for a "typebar page printer".
