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