Jacotot, Joseph (1770-1840), French educationalist, was born at Dijon, at whose university he was professor of Latin at nineteen. He was a zealous Revolutionist, and served in Belgium in 1782. He afterwards returned to his native town, where he became professor of "method of sciences," mathematics, and Roman law successively. In 1815 he was elected to the French Assembly, but afterwards went to live at Brussels, and was given an appointment in Louvain University. He returned to France after the Second Revolution. His system, which was adopted in Belgium, is set forth chiefly in his Enseignement Universal, Langue Maternelle (1823).
