Thomas Earnshaw (1749-1829)
Thomas Earnshaw (1749-1829)
Thomas Earnshaw was a watchmaker who improved and simplified the pioneering chronometer designs of John Harrison (1693-1776) and John Arnold (1736-1799), and who could be described as the father of the modern chronometer. He devised the spring detent chronometer escapement and his own form of temperature-compensated chronometer balance in 1782, and was the first to make chronometers that were simple and cheap enough to make them viable instruments of navigation.
