Gaston Milhaud (10 August 1858, Nîmes – 1 October 1918, Paris) was a French philosopher and historian of science.
Gaston Milhaud studied mathematics with Gaston Darboux at the École Normale Supérieure. In 1881 he took a teaching post at the University of Le Havre. In 1891 he became professor of mathematics at Montpellier University, and in 1895 became professor of philosophy there.[1] In 1909 a chair in the history of philosophy in its relationship to the sciences was created for him at the Sorbonne. Milhaud's successor in the chair was Abel Rey.
