Lioré et Olivier. Lioré-et-Olivier was a French manufacturer of aircraft of the 20th century, founded in 1912  by Fernand Lioré and Henri Olivier.

History
The Société de Constructions Aéronautiques d'hydravions Lioré-et-Olivier had three factories, located in Argenteuil, Clichy, Hauts-de-Seine and Rochefort, Charente-Maritime.

The company was nationalized in 1936, following which it was merged with Chantiers aéronavals Étienne Romano, Potez, CAMS and SPCA in order to form the Société nationale des constructions aéronautiques du Sud-Est (SNCASE) on 1 February 1937. The factory at Rochefort, however, went into SNCASO.
