Pierre Paul Leroy-Beaulieu

In 1867, he won a prize offered by the Academy of Moral and Political Sciences with an essay entitled L'Influence de état moral et intellectuel des populations ouvrières sur le taux des salaires.

In 1872, Leroy-Beaulieu became professor of finance at the newly founded École Libre des Sciences Politiques, and in 1880 he succeeded his father-in-law, Michel Chevalier, in the chair of political economy in the Collège de France.

Among them may be mentioned his Recherches économiques, historiques et statistiques sur les guerres contemporaines, a series of studies published between 1863 and 1869, in which he calculated the loss of men and capital caused by the great European conflicts.

He also founded in 1873 the Économiste français, on the model of L'Economiste belge by Gustave de Molinari.

Leroy-Beaulieu may be regarded as the leading representative in France of orthodox political economy, and the most pronounced opponent of protectionist and collectivist doctrines.
