Thomas TompionDied 20 Nov 1713 at age 74 (baptized 25 Jul 1639).Most famous English clockmaker of his time, especially known for watchmaking improvements. He worked closely with experimental physicist Robert Hooke, and in 1675, following Hooke's design, Tompion made one of the first English watches regulated by a balance spring. In 1695, with Edward Barlow and William Houghton, he patented the cylinder escapement (a controlling device) that allowed use of a horizontal wheel, enabling Tompion to make the first of the flat and more compact watches.[Image: Bracket clock with oak case ebony veneer, and gilt bronze mounts by Tompion, c. 1690.] |
