Geography
A farming village situated by the banks of the river Yères in the Pays de Caux, at the junction of the D16 and the D ...
– 21 September 1965) was a French pharmacist and chemist, whose name is associated with the
Delépine reaction for the preparation of
primary amines.
He studied at the
Sorbonne and at the École Supérieure de Pharmacie in
Paris, receiving his doctorate in 1898 with the thesis ''Amines et amides dérivés des aldéhydes'' ("The
amines and
amide derivatives of
aldehydes"). From 1895 to 1902 he served as ''préparateur'' at the
Collège de France, where he worked in the laboratory of
Marcellin Berthelot. In 1902 he was named chief pharmacist to the hospitals of Paris, a position he maintained up until 1927.

agrégé'' at the École Supérieure de Pharmacie, attaining the chair of
hydrology and hygiene in 1913. In 1930 he was appointed a professor of
organic chemistry at the Collège de France.

(biography)
In 1927 he became a scientific advisor for Etablissements Poulenc, and subsequently was named director of pharmaceutical research for Rhône-Poulenc.[ In 1930 he became a member of the Académie des sciences.][
His work involved research in the fields of organic, inorganic and general chemistry. He made contributions in his investigations of terpenes, platinum group metals ( iridium, rhodium), sulfur compounds, et al. In 1935 he described a general method for catalytic hydrogenation with Raney nickel.][ Also, when experimenting with thiocarbonic esters and related bodies, he discovered the phenomena of "oxyluminescence". In addition, he is credited for introducing a new process for preparation of pure tungsten.][
