Camille-Ernest Labrousse (Barbezieux, Poitou-Charente, 16 March 1895 – 24 May 1988, Paris) was a French historian specializing in social and economic history.
Labrousse established a historical model centered on three nodes—economic, social and cultural—inventing the quantitative history sometimes now called "cliometrics".
Eschewing biographies and the narrative accounts of individual witnesses, which have provided the backbone of traditional historiography, he applied statistical methods and influenced a whole generation.
Fernand Braudel said that if it were not for Labrousse, "historians would never have set to work as willingly as they did on the study of wages and prices".
Labrousse's prominence was also a result of his post at the Sorbonne, where he supervised a generation of French post-doctoral thèses and his organizational skills from the 1950s onwards in leading team research efforts that were models of the historian's craft.His first great work was his Esquisse du mouvement des prix et des revenus en France au XVIIIe siècle ("Sketch of the movement of prices and revenues in France during the 18th century", 1932), the result of his law dissertation under the direction of Albert Aftalion.
In 1948 he chaired a celebrated conference inquiring into "how revolutions are born," focusing on the French revolutions of 1789, 1830 and 1848, and applying to them his social, economic and political methodology.
In 1979 he received the Balzan Prize for History (ex aequo with Giuseppe Tucci).
Labrousse had begun as a student of François Simiand.
