From 1872 he worked as an assistant in the laboratory of Michel Eugène Chevreul (1786-1889) at the ''Muséum national d'histoire naturelle''. In 1883 he succeeded François Stanislas Cloez (1817-1883) as ''aide-naturaliste'', and from 1890 to 1915 was chair of applied organic chemistry at the museum.
