----------------- HES POSTING ----------------- Mike [Lynch], You are correct. The wording in the IEA paper is confusing and can lead one to believe that it was Hermann. Apparently Hermann was the first to argue for the generality of upward-sloping supply curves that then led to (Streissler, IEA, p. 13): "But there was also one further consequence of Hermann's thought. In the fourth edition of his theory text-book, and ever after, Rau in an appendix (Rau 1841, p. 525-527) presented an explicitly argued demand curve and a demand and supply diagram. It was not the first in the history of economic thought: Cournot (1838) had preceded him by three years. But it is the first with price on the vertical and quantity on the horizontal axis: the Marshallian demand curve is born!" I apologize for my careless reading and thus my misleading of those on this list. It was Rau, not Hermann.
