Teletype Corporation
- this page is a stub
Teletype Corporation, abbreviated Teletype, was an American manufacturer of
teleptypewriters, also known as telex machines,
based in Skokie (Illinois, USA).
The company was founded in 1928 after renaming the
Morkrum-Kleinschmidt Company — itself established in 1902 —
to the name of its trademark equipment:
Teletype. The company was part of
Western Electric (WE) and was merged into
AT&T in 1930.
Nevertheless it remained an independent operation.
After AT&T was split-up in 1982,
Teletype was gradually wound down and was finally dissolved in 1990 [1].
The company is well-known for its range of 5-level (ITA-2)
teleprinters (telex machines) and associated peripherals, that were used
worldwide by telecom providers like AT&T Bell.
In the 1960s and 70s the company also produced a range of
8-level ASCII (ITA-5) teleprinters that were
used as input/output terminals for the first generations of mainframe
and mini computers.
Although Teletype was a registered trademark, it is often
used as a generic expression for teletypewriters and teleprinters.
In modern computer operating systems, such as Unix and Linux, simple (virtual)
terminal access to the command line — typically via serial or network port — is
commonly referred to as the TTY protocol or the TTY port.

NOT IN COLLECTION —
At present, Crypto Museum does not have any Tyletype equipment in its
collection. We do however hold documentation of several Teletype
devices in our archives.
This page and its sub-pages serve as a repository
for documentation and other information about various Teletype models
and peripherals.
Below is a timeline that shows the history of the Teletype business.
The company was founded in 1902 as the Morkrum-Kleinschmidt Company,
which was part of Western Electric (WE). It sold teletypewriters under
the brand name Teletype. In 1928, the company was renamed Teletype
after its brand name. Just two years later, in 1930. the Teletype business
was acquired by AT&T, but continued as an independent entity within AT&T.
On 8 January 1982, following an anti-trust law suit that had started in
1974, the teleprinter business was split-off as AT&T Teletype. Two years later,
in 1984, the rest of AT&T was split into seven separate companies, which became
known as the seven 'Baby Bells'. AT&T Teletype was finally wound down and
dissolved in 1990.
