Jean-Baptiste Say (1767-1832) has been described as a revolutionary, an author of scholarly books and popular tracts, a social philosopher, a successful entrepreneur-a remarkable Renaissance man. He is best known as author of the law of markets, known as Say's Law, and as the first to coin the term "entrepreneur." Say's concern with the average interested citizen and his zeal for economic education for the masses is most apparent in his classic work, A Treatise on Political Economy.
