HILTON (Simpson), Harold.
(1876 - 1974)

(Born: Ickham, Kent, England, 22 October 1876; Died: Oxford, England, 4 April 1974) English mathematician & crystallographer.

From 1895 to 1898, Hilton studied at Oxford, eventually receiving his D.Sc in 1913. In 1902, he became assistant lecturer in mathematics at the University of Banger, in North Wales. In 1907, he accepted a position as assistant professor of mathematics at Bedford College, London. Finally, in 1912, Hilton became professor of math at the University of London where he remained the rest of his career. In 1939, he changed his last name to Simpson.

Scarce. This work collects together the results of various mathematical theories of crystallography, which had not previously been published in English. Through a careful examination of their properties, Hilton was able, with minor adjustments, to derive in a simple manner the 32 point groups and the 230 space groups. However, no practical applications of the results obtained are included. Hilton provides a full account of the geometrical theory of crystal structure as outlined by Bravais, Jordan, Sohncke, Fedorov, Schoenflies and Barlow.
