The Teletype Corporation had its roots in the Morkrum Company. In 1902, electrical engineer Mr. Frank Pearne approached Mr. 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’. In 1904, Krum filed a patent for a ‘type wheel printing telegraph machine’ which was issued in August, 1907.

In 1906, the Morkrum Company was formed with the company name combining the Morton and Krum names and reflects the financial assistance provided by Joy Morton. This is the time when Charles Krum's son, Howard Krum, joined his father in this work. It was Howard who developed and patented the start-stop synchronizing method for code telegraph systems, which made possible the practical teleprinter.

In 1908, a working teleprinter was produced, called the Morkrum Printing Telegraph, which was field tested with the Alton Railroad.

In 1910, the Morkrum Company designed and installed the first commercial teletypewriter system on Postal Telegraph Company lines between Boston and New York City using the "Blue Code Version" of the Morkrum Printing Telegraph.

In 1925 the Morkrum Company and the Kleinschmidt Electric Company merged to form the Morkrum-Kleinschmidt Company. In December 1928, the company changed its name to the less cumbersome "Teletype Corporation".

In 1930, the Teletype Corporation was purchased by the American Telephone and Telegraph Company for $30,000,000 in stock and became a subsidiary of the Western Electric Company. While other principals in the Teletype Corporation retired, Howard Krum stayed on as a consultant.
