Abraham Louis Breguet
Abraham Louis Breguet (Neuchâtel, Switzerland, January 10, 1747 – Paris, France, September 17, 1823), also known simply as Breguet, was a renowned Swiss inventor, famous for his contributions to watchmaking.
Biography
In 1762, at the age of 15, he moved to France and began working independently until, in 1775, he founded the prestigious watchmaking firm Breguet, which to this day preserves the spirit and dedication of its founder.
Between the early 1780s and 1816, Breguet made numerous inventions that shaped the pocket watch, which would later evolve into the wristwatch as we know it today. One of his most famous creations, patented in 1801, is the Tourbillon, one of the most highly regarded complications in haute horlogerie. The Tourbillon consists of a mechanism that rotates the balance wheel and escapement over their axis, typically once per minute, to counteract the negative effects of gravity on the watch's precision.
His outstanding reputation and dedication to precision watchmaking led to his appointment to the Academy of Sciences in 1816, where he conducted numerous experiments to achieve absolute accuracy in his timepieces. His watches were used by many explorers and military leaders of the time, including Napoleon, who carried Breguet timepieces during his campaigns.
Among Breguet's notable inventions is the trimetallic thermometer, known as the Breguet thermometer, developed in 1817. It was designed to prevent variations in ambient temperature from affecting the accuracy of his watch springs.
Breguet's legacy continued through his family. His grandson, Louis Breguet (1804–1883), contributed to the development of the electric telegraph, and his great-grandson, Louis Charles Breguet (1880–1955), became a pioneer in aviation.
Death
On September 17, 1823, Abraham Louis Breguet passed away at the age of 76. His son took over the leadership of the Breguet watchmaking firm, which in 1840 created the first watch with an integrated bimetallic strip thermometer.
