by Lucien Poincaré
Born in Bar-le-Duc on July 22, 1862, Lucien Poincaré was a French physicist who went on to build an important career in education administration. A reference work available online describes him as having had a distinguished academic career before becoming inspector-general of physical science in 1902.
The same source says he later served as director of secondary education at the Ministry of Public Instruction in 1910, director of higher education in 1914, and rector of the University of Paris. Those posts place him among the key figures shaping French education in the early 20th century.
He died in 1920. While brief English-language information is easier to find than fuller biographical detail, the available record clearly shows a life spent connecting scientific training with public education at the highest levels.
