EMILE BAUDOT
Emile Baudot was born in France on the II-th September 1845, very early in the era of the electric telegraph. His father was a farmer, his mother a dressmaker.
His formal education was limited to that provided by the local primary school. His vocation was to follow in his father’s footsteps and he trained as a farmer.
At the age of 24 Baudot left agricultural work and joined the telegraph service where he was to
become famous as the inventor of a new telegraph system. At the time he joined the Telegraph
Administration he was ignorant about the existence of printing telegraph equipment. His knowledge was limited to a superficial understanding of the Morse and the dial telegraphs. In September 1869 he was sent to Paris for a course on the famous Hughes telegraph, which automatically printed its message at the receiver in Roman type. Baudot studied the Hughes equipment until the following Spring.
After completing his course Baudot joined the Central Paris telegraph station in July 1870 before
moving to Bordeaux at the end August. By then the Franco-Prussian War had broken out and by the end of the year he had been commissioned with the rank of Lieutenant and was serving with the military telegraph service of the Second Army. After the war ended, Baudot once again become a civilian and returned to duty in Paris in February 1872.
Baudot had already started to acquire a reputation as an inventor for improvements he had
suggested to existing equipment. He was now encouraged by the Chief Inspector of the exchange to design a “multiple Hughes”. But in the evening he was designing his own printing telegraph. On the 25-th July, 1874 Baudot sent a letter to the authorities describing his proposals. They recommended a budget of 2000 francs for the construction of a prototype. In December the following year (1875) tests began which led to a quintuple telegraph being made for regular service.
Baudot died in 1903 at the early age of 58. Montoriol described him as prematurely worn out by a life of labour without rest but, unlike many inventive genuses, he was privileged to have seen his genius “radiate around the world”.
His telegraph met with rapid success when it was introduced in France and was soon in use
throughout Europe, India and South America. An early British use was on the Anglo-French cable and it was used extensively by the British Telegraph Service.
