The Wheatstone automatic transmitter was an electromechanical device invented by Sir Charles Wheatstone in 1858 that read punched paper tape to send Morse code messages rapidly and automatically over telegraph lines
Wheatstone type transmitter was produced by The Great Northern Telegraph Company (Det Store Nordiske Telegrafselskab A / S) that was founded in Denmark in June 1869.
It was set up as a merger of three recently established telegraph companies initiated by Danish industrial mogul Carl Frederik Tietgen.
The aim of the firm was to create a worldwide telegraph company. The former headquarters of the GNTC on The Bund, Shanghai. The starting point of The Great Northern Telegraph Company (now GN Store Nord) was a concession agreement, which C.F. Tietgen made with the Russian Tzar in 1869.
The agreement gave The Great Northern Telegraph Company exclusive rights – and obligations – to establish and run a telegraph line in Russia. This represented a great pioneer task for the company in establishing connections from Europe to the Far East.
