William Lax FRS (1761 – 29 October 1836) was an English astronomer and mathematician who served as Lowndean Professor of Astronomy and Geometry at the University of Cambridge for 41 years.
Lax was born in Ravensworth in the North Riding of Yorkshire. He attended Trinity College, Cambridge and graduated Bachelor of Arts as the Senior Wrangler and first Smith's Prizeman of his year. He was elected a fellow of Trinity College, ordained as a minister, and received his Master of Arts. Lax was granted the livings of vicar of Marsworth, Buckinghamshire and of St Ippolyts near Hitchin, Hertfordshire, where he erected an observatory.
Lax was best known for his Remarks on a Supposed Error in the Elements of Euclid (1807) and his work regarding the Nautical Almanac, which was an important reference for navigation in the period. An obituary claimed that "To whatever Professor Lax applied, he made himself completely master of it". His daughter married Andrew Amos and through that line Lax is the grandfather of Sheldon Amos and the great grandfather of Maurice Amos, a notable legal dynasty.
