Telegraph operators transmitted messages using Morse code, requiring the ability to interpret and encode messages. They worked in various settings, including newsrooms and government agencies, and played a crucial role in communication before the advent of modern technology.
A telegraph operator operates telegraph equipment to maintain communication over radio waves. This career is largely obsolete as telegraphs have been replaced by other methods of communication, including radio and satellite. From the 19th century, when the telegraph was originally invented, to the early 20th century, when other technology began to replace it, telegraphers transmitted signals from ships, between locations on land, and in military conflicts. Telegraph operators, as they were also known, included a mix of men and women.
Operating a telegraph required multiple skill sets. The telegraph operator needed to be able to listen and interpret incoming messages, converting the telegraph code into meaningful text to relay to the intended recipient. They also needed to encode and send messages, and in some cases they also relayed messages along the telegraph line. For example, a radio telegraph operator might receive a message aboard a ship destined for a recipient across the ocean. The original message could not make the trip in one transmission and was instead retransmitted through a series of telegraph operators to reach its final destination.
Morse code was the standard language used by telegraph operators. People who worked for the military also used cryptography in their work to send messages securely. If intercepted, these messages would be meaningless to people other than the intended recipients. Codebreakers worked on developing new codes, as well as interpreting codes used by enemies to track clandestine transmissions.
The telegraph operator would use a device known as a telegraph switch to send signals over a wired telegraph system or over a wireless radio network. The switch allowed for burst transmissions that could be long or short depending on how the telegraph operator activated it, allowing for the creation of a code based on stringing long and short signals together. Telegraphists worked in a variety of settings, including companies with telegraph agencies such as newsrooms. Some were employed by government agencies and handled field and office telegraph transmissions.
Other jobs for a telegraph operator included jobs for companies that sent telegraphs on demand from customers. Members of the public could arrive at an office to compose and send billed messages over the line and receive messages through those same offices. Telegrams, as they were known, provided a means for rapidly communicating important information in an era before personal telephones, radio signals, the Internet, and other means of communication.
