Sommerville studied at the
University of St Andrews. He taught there from 1902 to 1914. He was elected a Fellow of the Royal Society of Edinburghin 1911. In 1915 Sommerville went to New Zealand for an appointment at the Victoria College of Wellington.
Sommerville most famous for his work on geometries in higher dimensions (in addition the classical geometries: Euclidean, spherical and hyperbolic). He found "3d" geometries in dimension "d". He also discovered and proved the celebrated
Dehn-Sommerville equationsfor the number of faces of convex polytopes.
