Olry Terquem

From Wikipedia, the free encyclopedia

Olry Terquem (16 June 1782–1862) was a French mathematician, best known for his work in geometry, where he proved Feuerbach's theorem about the nine-point circle of a triangle. As one of the editors of the Nouvelles Annales, he published in 1842 the second analytical proof of the theorem, that the nine-point circle touches the incircle and the excircles of a triangle.

Terquem was among the first who recognized the importance of the work of Évariste Galois.
