Léon Eyrolles (14 December 1861 – 3 December 1945) was a French politician and entrepreneur. In 1891, he created the first École Spéciale des Travaux Publics and later a correspondence school.
Eyrolles developed his educative skills as he helped fellow site managers to pass civil servant selective exams. In 1902 he bought a large piece of land to extend the school and in 1924 he became the mayor of the newly founded city of Cachan which was split from the city of Arcueil.
