Extractions: In order to appreciate Emile Lemoine's role in the subject of triangle geometry, it is helpful to start with a bird's eye view of the history of the subject. First, there was a wave of ancient Greek developments, as recorded in Euclid's Elements. The second wave began with the discovery of the Fermat point and continued into the early twentieth century. The third wave, now rolling, dates from the advent of computers. Lemoine has been called the originator of an enormous surge of interest in triangle geometry that took place during the second of the three waves. Lemoine did not publish original mathematical results after 1895, but in 1894, he helped C. A. Laisant establish the journal , and he served as its editor for several years. Many of Lemoine's contributions can be found in Nathan Altshiller Court, College Geometry, In addition to Lemoinian Geometry (14 pages in Chapter 10), Court presents a section of Historical and Bibliographical Notes, in which he writes: Proceedings pp. 90-91, and was also published in [

He worked in the gas inspection service from 1886 until 1896. A symmedian of a triangle from vertex A is obtained by reflecting the median from A in the bisector of the angle A . He proved that the symmedians are concurrent, the point where they meet now being called the Lemoine point. Among other results on symmedians in Lemoine's 1873 paper is the result that the symmedian from the vertex A cuts the side BC of the triangle in the ratio of the squares of the sides AC and AB . He also proved that if parallels are drawn through the Lemoine point parallel to the three sides of the triangle then the six points lie on a circle, now called the Lemoine circle. Its centre is at the mid-point of the line joining the Lemoine point to the circumcentre of the triangle. These results are interesting but Lemoine's next venture failed to interest many mathematicians. He produced a classification of geometry according to five operations:-

Extractions: Le Souvenir Après la signature de l'armistice le 11 novembre 1918, il restait à honorer la mémoire de tous ceux qui perdirent la vie durant ces quatre années de guerre. Toutes les communautés ( les Français, les Britanniques, les Canadiens, les Australiens, les Américains, les Allemands ) bâtirent des stèles, des monuments du souvenir et des cimetières en hommage aux combattants défunts. A Maing, deux sites évoquent le souvenir des victimes militaires de ce conflit. Le monument aux morts Un premier obélisque symbolique (ci-contre) fut érigé au grand cimetière, le temps de permettre l'édification d'un monument aux morts officiel. Celui-ci , également en forme d'obélisque, fut élevé près de la Grand Place, sur un site qui devint " la Place du Souvenir ". Il reçut la bénédiction de l'abbé Leprette , en présence de nombreuses personnalités. Sur la face antérieure, un soldat blessé, le fusil pendant , se tient l'épaule droite. Le monument de Maing s'inscrit donc bien dans la lignée du souvenir et du chagrin, et non pas dans celui du triomphalisme. En façade également, la Croix de Guerre et deux palmes, de chêne et de laurier, deux inscriptions : " Maing à ses enfants morts pour la France " et " A nos héros 1914-1918 " Sur les trois autres faces sont inscrits les noms des soldats morts pour la France entre 1914 et 1918, ainsi que les victimes civiles (sur la face postérieure). Sur le socle ont été rajoutés les noms des victimes civiles et militaires de la seconde guerre mondiale. L'architecte fut M. Armbruster et le statuaire M. Raset C'est à la même époque qu'une partie de la rue de l'En Haut fut rebaptisée
Extractions: Previous (Alphabetically) Next Welcome page Emile Lemoine was educated at the Ecole Polytechnique graduating in 1860. He remained there teaching for six years when he retired through ill health. As a civil engineer he rose to the rank of chief inspector and in that capacity he was responsible for the gas supply to Paris. He worked in the gas inspection service from 1886 until 1896. Lemoine work in mathematics was mainly on geometry. He founded a new study of properties of a triangle in a paper of 1873 where he studied the point of intersection of the symmedians of a triangle. He had been a founder member of the Association Francaise pour l'Avancement des Sciences and it was at a meeting of the Association in 1873 in Lyon that he presented his work on the symmedians. A symmedian of a triangle from vertex A is obtained by reflecting the median from A in the bisector of the angle A. He proved that the symmedians are concurrent, the point where they meet now being called the Lemoine point. Among other results on symmedians in Lemoine's 1873 paper is the result that the symmedian from the vertex A cuts the side BC of the triangle in the ratio of the squares of the sides AC and AB. He also proved that if parallels are drawn through the Lemoine point parallel to the three sides of the triangle then the six points lie on a circle, now called the Lemoine circle. Its centre is at the mid-point of the line joining the Lemoine point to the circumcentre of the triangle.

Géométrographie, Ou Art Des Constructions Géometriques, Par Émile
Extractions: Euclid's Elements and other remnants from ancient Greek times contain theorems about triangles and descriptions of four triangle centers: centroid, incenter, circumcenter, and orthocenter. Later triangle geometers include Euler, Pascal, Ceva, and Feuerbach. In 1873, Emile Lemoine presented a paper "on a remarkable point of the triangle," now known as the Lemoine point or symmedian point. This paper, writes Nathan Altshiller Court ( College Geometry , page 304), "may be said to have laid the foundations...of the modern geometry of the triangle as a whole." Court also describes seminal papers by Henri Brocard and J. Neuberg and names Lemoine, Brocard, and Neuberg as the three co-founders of modern triangle geometry. An astonishing wave of interest and publications in triangle geometry swept through the last years of the 19th century and then collapsed during the early years of the 20th. However, many new gemstones in the fields of triangle geometry remained to be unearthed with new excavating tools, such as computers and methods from other areas of mathematics. All of this has led to the state of the art up to 1995, as described in Philip J. Davis

Lemoine Affair By Emile Faguet
Extractions: In a dramatic review by M. Emile Faguet The author of le Détour and le Marché - namely M. Henri Bernstein - has just had a play performed by the Gymnase company, or rather it is a mixture of tragedy and vaudeville, which is perhaps not his Athalie or his Andromaque , his l'Amour veille or his les Sentiers de la vertue , but rather is more like his Nicomède , which is in no way, as you may perhaps have heard through hearsay, an entirely contemptible piece and is in no way the utter shame of the human spirit. So far does this piece reach, I do not say above the clouds, but in short has reached to the clouds, that there is a little exaggeration, but of a justifiable success, M. Bernstein's piece is swarming with improbabilities, but with a foundation of truth. It is in this that l'Affaire Lemoine differs from la Rafale , and, generally, from M. Bernstein's tragedies, as it does from a good half of Euripides's comedies, which swarm with truths, but are built on a foundation of improbabilities. Moreover it is the first time that one of M. Bernstein's pieces has interested people, who have avoided them up until now. Consequently, that swindler Lemoine, wishing to perpetrate a dupe with his claim of having discovered the means to manufacture diamonds, appealed... to the biggest owner of diamond mines in the world. As improbabilities go you will tell me that this is one of the greatest. And that's the first. At the very least you would think that this potentate, who has had his mind on the most important business affairs in the world, would send Lemoine packing, like the prophet Nehemia, who proclaimed from the walls of Jerusalem to those below who were offering him a ladder for him to come down:
