Andrew Crommelin is perhaps best remembered for his accurate prediction of the return of comet 1P/Halley in 1910.
Crommelin was born in a family of French extraction in Ireland, a descendent of the founder of the Irish linen industry in Ulster. He was educated at Marlborough College and Trinity College Cambridge, graduating in 1886. For several years, Crommelin served on the staff at Lancing College, during which time he continued to pursue observational astronomy, his avocational interest since childhood. He was elected a fellow of the Royal Astronomical Society (RAS) in 1888.
In 1891, Crommelin joined the staff of Greenwich Observatory as a regular observer with the transit circle, the Airy altazimuth, and the Sheepshanks equatorial telescopes. Over time, he became expert in observing comets; computation of orbits for comets, and for asteroids, became his particular area of expertise.This is a preview of subscription content, log in to check access.
