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. The Russian authorities ran the actual construction work in Russia. They had already set up a telegraph line in parts of Siberia but were looking for a business partner to cover China and Japan before continuing the Russian line all the way east to Vladivostok. Thus, The Great Northern Telegraph Company was given the responsibility to establish and run its own telegraph line in Asia, and additionally, assisting the Russians with operations, maintenance, technical assistance and education. In the following years, the telegraph line expanded massively – both in Europe and in Asia. First, Oslo, London and Paris were covered. Later, operations took place along the coast of China ranging from Hong Kong to Shanghai and further into Japan where the first telegraph station opened in Nagasaki in 1897. In addition to the telegraph line, telegraph stations and offices opened at several locations.
