Philippe Landrieu (1872–1926), un chimiste engagé dans la politique expérimentale

From Jean-Baptiste Dumas to Chaïm Weizmann and to Margaret Thatcher, including Alfred Naquet, Marcelin Berthelot, Auguste Scheurer-Kaster, Stanislao Cannizzaro, Frédéric Joliot etc., there are few chemists who, at one time or another, have not been tempted to enter politics. Philippe Landrieu is certainly one of the lesser known of this group, even if he had a laudatory Obituary in both the Bulletin de la Société chimique de France, and La Nouvelle Revue socialiste. The events in which he was involved, the utopias for which he was searching, his double career, and his scientific work, nothing was ordinary in his busy life. This Note, as well as placing him in the social history of the last century, will also recall his work as a chemist, and the unresolved problems in which he was interested.
