Peter Litherland (1756–1805)
Peter Litherland was a watchmaker and inventor. He was born in Warrington and later moved to Liverpool, which was then the centre of the watchmaking trade. In 1791 he patented the rack lever escapement for watches, which was more accurate than the commonly used verge escapement. One of his watches is in display in the World Museum Liverpool.
