James Ivory's last papers on the "Figure of the Earth" (with biographical additions).

Alexander Duncan Davidson Craik

Research output: Contribution to journalArticlepeer-review


Sir James Ivory, FRS (1765-1842), was best known for his work on the gravitational attraction of ellipsoids, and the 'Figure of the Earth'; a problem that attracted great attention. The mixed reception of Ivory's late work on this topic is examined. Although refereed fairly and favourably by George Biddell Airy, it was attacked by Isaac Todhunter long after Ivory's death. Further biographical information about James Ivory is given. This includes evidence that reveals the identity of his mother and shows that he was not born illegitimately, as I had claimed previously.
