The teleprinter evolved through a series of inventions by a
number of engineers, including Royal Earl House, David Edward
Hughes, Emile Baudot, Donald Murray, Charles L. Krum, Edward
Kleinschmidt and Frederick G. Creed. Teleprinters were invented in
order to send and receive messages without the need for operators
trained in the use of Morse code. A system of two teleprinters,
with one operator trained to use a typewriter, replaced two trained
Morse code operators. The teleprinter system improved message speed
and delivery time, making it possible for messages to be flashed
across a country with little manual intervention.
This began in 1846 with Royal Earl House patenting his printing
telegraph through 1924 then Creed & Company, founded by
Frederick G. Creed, entered the teleprinter field with their Model
1P. Additional minor improvements were invented from then into the
1960s.
