Irving Fisher

Irving Fisher (February 27, 1867 Saugerties, New York April 29, 1947, New York) was an American economist, health campaigner, and eugenicist. He was one of the earliest American neoclassical economists and, although he was perhaps the first celebrity economist, his reputation today is probably higher than it was in his lifetime. Several terms are named after him, including the Fisher equation, Fisher hypothesis and Fisher separation theorem.
