Jules Lechevalier

Jules André Louis Lechevalier (21 April 1806 – 10 June 1862) was a French utopian socialist, economist and anthropologist. He was at first a Saint-Simonian, then a Fourierist and a collaborator of Proudhon. After 1855 he was also known as Jules Lechevalier Saint-André. His years of birth and death are sometimes given as 1800 and 1850, respectively, but this is incorrect. Provided by Wikipedia
