He worked as a professor of anatomy at Lyon from 1904 under Leon Testut and moved to Nancy in 1908 where he taught anatomy. He worked under Adolph Nicolas and collaborated with Paul Bouin on Leydig cells. He worked at the institute of embryology at Strasbourg from 1919 and published more than 300 works relating to endocrinology, anatomy, cytology, embryology and teratology. His fellow researchers at Strasbourg include P. Vintemberger, Etienne Wolff, and S. Lallemand (his own daughter).

He was Knighted with the Legion of Honour (1921).
