Charles Wheatstone developed the automatic Morse sender and receiver in the mid-nineteenth century. The sender used two-unit perforated tape which had to be prepared by hand. Creed and Co Ltd designed a set of equipment in the early 1920s which automated the entire process of preparing, sending and receiving telegraph messages. Known as the 'high-speed Morse system', it comprised a keyboard perforator for preparing the tape, a motorised sender, a reperforator for making a tape of received messages and a motorised high-speed printer which could print up to 100 words a minute. Such equipment remained in widespread use in newspaper offices and government departments until the 1950s.
