Jean Baptiste Dutertre (1684-1734) was born on Nobember 6, 1684 in Rennes; his father was the watchmaker François Dutertre. He went to Paris around 1701 and apprenticed with Jean-Baptiste Le Noir. Dutertre worked in the Rue Harlay near the Quai des Orfèvres from 1712 on and soon gained a reputation as an excellent maker.
Together with Pierre le Roy Dutertre refined the duplex escapement; he also invented the Dutertre escapement for pendulum clocks, a recoil escapement used for double pendulum clocks. Jean Baptiste Dutertre died on July 22, 1734 in Paris at the age of 49.
