Achilles Nicolas Isnard (1749-1803) was an engineer with a keen interest in political economy. His principal economic work the Traité des richesses published in 1781, is known for its mathematical demonstration of market equilibrium. Despite Isnards role in founding mathematical economics, his work is under-studied today and this superbly written new book from Richard Van Den Berg seeks to rectify this. With this comprehensive, passionately argued book, A. N. Isnard will finally achieve his place at the heart of discussion on the origins of mathematical economics. Copyright (C) Muze Inc. 2005.
