Émile Lemoine
Émile Michel Hyacinthe Lemoine (; 22 November 1840 – 21 February 1912) was a French civil engineer and a mathematician, a geometer in particular. He was educated at a variety of institutions, including the Prytanée National Militaire and, most notably, the École Polytechnique. Lemoine taught as a private tutor for a short period after his graduation from the latter school. Lemoine is best known for his proof of the existence of the Lemoine point (or the symmedian point) of a triangle. Other mathematical work includes a system he called ''Géométrographie'' and a method which related algebraic expressions to geometric objects. He has been called a co-founder of modern triangle geometry, as many of its characteristics are present in his work. For most of his life, Lemoine was a professor of mathematics at the École Polytechnique. In later years, he worked as a civil engineer in Paris, and he also took an amateur's interest in music. During his tenure at the École Polytechn ...

La Trompette (musical Society)
La Trompette was a chamber music society based in Paris, founded by Émile Lemoine in January 1861. It has been credited with a major role in the propagation of chamber music in France. Performers included Camille Saint-Saëns, Louis Diémer, Paul Taffanel, Felix Weingartner, Pablo Casals, Harold Bauer, Wanda Landowska, Alfred Cortot, and Serge Koussevitzky. History The society was founded in 1861 by Lemoine and three fellow students at the École Polytechnique, who enjoyed playing quartets. The name "La Trompette" stemmed from a "non-sympathetic remark a teacher once made to quiet the quartet". With increasing popularity, it became a weekly private concert series. In 1878, the society moved to the hall of the Horticultural Society at 84 Rue de Grenelle, which seated 850. Lemoine kept the nature of the society informal, considering himself not a manager or director but a host, and members of the society not to be subscribers but his friends, even though an annual monetary contribu ...
