Lucien Poincaré

Lucien Poincaré (born July 22, 1862 in Bar-le-Duc , † March 9, 1920 in Paris ) was a French physicist and one of the inspectors general of the secondary schools in France.

He was the brother of the French President (from 1913 to 1920) Raymond Poincaré and cousin of Henri Poincaré . His father Antoni Poincaré (1829-1911), a graduate of the École Polytechnique , was inspector for bridges in Bar-le-Duc.

Poincaré studied from 1883 at the École normal supérieure with a degree in mathematics in 1885 and in physics in 1887 (Agrége in physics also in 1887). In 1886 he taught at the Lyceum in Bourges and in 1887 he became a taxidermist (Agrégé préparatoire) at the physics faculty of the Sorbonne under Edmond Bouty . In 1890 he received his doctorate with a dissertation on electrolytes at the Sorbonne ( Recherches sur les électrolytes fondus ) and was from 1891 a physics teacher at the Lyceum in Marseille and from 1893 at the Lycée Louis-le-Grand in Paris. In 1894 he was Maitre de conferences at the École normal de jeune filles in Sèvres (where he taught until 1900) and in 1895 Chargé de cours at the Sorbonne (where he taught physics until 1900 at the same time as Paul Janet ). In the following year he was also delegated as professor to the École supérieure d'électricité. In 1900 he became rector of the Académie de Chambéry and Pierre Curie was his successor on his chair. In 1902 he became general inspector for teaching physics in secondary schools in France. In 1910 he became inspector for teaching at high schools (Enseignement secondaire) and in 1914 at universities (Enseignement supérieure). In 1917 he became Vice Rector of the Académie de Paris as the successor to Louis Liard .

He wrote a popular science book on then modern physics (1906), which received the Prix Hébert of the Académie des Sciences. He was co-editor of the Journal de physique théorique et appliqué of the French physical society, which he chaired in 1911.
