Early Life and Education
Andrew Claude de la Cherois Crommelin was born in Chéroy, France, on February 9, 1865. His father was a French army officer, and his mother was English. Crommelin received his early education in England, first at Marlborough College and then at Trinity College, Cambridge.
Career
After graduating from Cambridge, Crommelin joined the staff of the Royal Greenwich Observatory. He was a member of several eclipse expeditions, including the successful expedition to observe the total solar eclipse of May 28, 1900, in North Carolina.
Crommelin specialized in the study of comets. In 1929, he published a paper in which he showed that three previously known comets—Forbes' Comet (1928 III), Coggia-Winnecke Comet (1873 VII), and Pons' Comet (1818 II)—were actually the same periodic comet. This comet was renamed Pons-Coggia-Winnecke Comet. After Crommelin's death in 1930, it was renamed again, in his honour, as Comet 27P/Crommelin.
Leadership in the Astronomical Community
Crommelin was also active in the astronomical community. He served as President of the British Astronomical Association from 1904 to 1906. He was also a member of the Royal Astronomical Society, serving as its Secretary from 1917 to 1923 and as its President from 1929 to 1930.
Death and Legacy
Crommelin died in London on September 19, 1930. He is remembered as one of the leading astronomers of his time, and his work on comets continues to be important today. In 1948, Comet 27P/Crommelin was renamed in his honour, recognizing his significant contributions to the field of astronomy.
