Richard Cantillon (1680s – May 1734) was an Irish-French economist and author of Essai sur la Nature du Commerce en Général (Essay on the Nature of Trade in General), a book considered by William Stanley Jevons to be the "cradle of political economy". Although little information exists on Cantillon's life, it is known that he became a successful banker and merchant at an early age. His success was largely derived from the political and business connections he made through his family and through an early employer, James Brydges. During the late 1710s and early 1720s, Cantillon speculated in, and later helped fund, John Law's Mississippi Company, from which he acquired great wealth. However, his success came at a cost to his debtors, who pursued him with lawsuits, criminal charges, and even murder plots until his death in 1734.
