Louis Clément François Breguet
Louis Clément François Breguet (born December 22, 1804 in Paris , † October 27, 1883 there ) was a French watchmaker , physicist and designer. He invented some electrical instruments and was instrumental in the development of electrical telegraphy .
Life
Breguet was the grandson of Abraham Louis Breguet , a Swiss watchmaker and in 1775 the founder of the famous watch manufacturer Breguet . In preparation for the later takeover of the family business, he enjoyed an apprenticeship in Switzerland . In 1833, Antoine Louis Breguet (1776-1858) then handed the company over to his son Louis.
When the French government decided on November 23, 1844 to set up an experimental telegraph line along the Paris-Rouen railway line, he was entrusted with the management.
In 1856 Breguet built a public clock system in the center of Lyon and on October 26, 1866 he registered a patent for a special wheel clock that used a 25 cm long tuning fork to regulate the rate. In addition to the construction of clocks and pocket watches , Breguet was also interested in researching electricity and its possible applications, and later also telegraphy. Together with the physicist Antoine Masson , he developed the first induction coils in 1841 . Heinrich Daniel Rühmkorff used this knowledge about ten years later to manufacture his Rühmkorff spark inductors .
In 1870, Breguet finally decided to concentrate on electricity and to leave watchmaking. He passed the management of the watch manufacture into the hands of his foreman Edward Brown, whose family managed the company for another hundred years.
Since then, Breguet has dealt exclusively with telegraphy and the emerging telecommunications. With his knowledge of clock technology, he developed various devices for telegraphy. Together with his son Antoine Breguet (1851–1882), he produced and sold the first Bell-type telephones on the French market.
Breguet's name is immortalized as one of the 72 names on the Eiffel Tower .
