This reproduction was printed from a digital file created at the Library of Congress as part of an extensive scanning effort started with a generous donation from the Alfred P. Sloan Foundation. The Library is pleased to offer much of its public domain holdings free of charge online and at a modest price in this printed format. Seeing these older volumes from our collections rediscovered by new generations of readers renews our own passion for books and scholarship.
William Graham Sumner (October 30, 1840 – April 12, 1910) was a classical liberal American social scientist. He taught social sciences at Yale, where he held the nation's first professorship in sociology. He was one of the most influential teachers at Yale or any other major school. Sumner wrote widely within the social sciences, with numerous books and essays on American history, economic history, political theory, sociology, and anthropology. He supported laissez-faire economics, free markets, and the gold standard. He adopted the term "ethnocentrism" to identify the roots of imperialism, which he strongly opposed. He was a spokesman against imperialism and in favor of the "forgotten man" of the middle class, a term he coined. He had a long-term influence on conservatism in the United States.
