Frederick Jackson Turner (November 14, 1861 – March 14, 1932) was an American historian in the early 20th century. He is best known for The Significance of the Frontier in American History. Born in Portage, Wisconsin, the son of Andrew Jackson Turner and Mary Olivia Hanford Turner, Frederick Jackson Turner graduated from the University of Wisconsin–Madison in 1884, where he was a member of Phi Kappa Psi Fraternity. He gained his Ph.D. in history from Johns Hopkins University in 1890 with a thesis on the Wisconsin fur trade. As a professor of history at Wisconsin (1890–1910) and Harvard (1910–1922), Turner trained scores of disciples who in turn dominated American history programs throughout the country. His emphasis on the importance of the frontier in shaping American character influenced the interpretation found in thousands of scholarly histories. His model of sectionalism as a composite of social forces, such as ethnicity and land ownership, gave historians the tools to use social history as the foundation of all social, economic and political developments in American history. At the American Historical Association, he collaborated with J. Franklin Jameson on major projects. Turner is remembered for his "Frontier Thesis", which he first published July 12, 1893, in a paper read in Chicago to the American Historical Association during the Chicago World's Fair. In it, he stated that the spirit and success of the United States is directly tied to the country's westward expansion. According to Turner, the forging of the unique and rugged American identity occurred at the juncture between the civilization of settlement and the savagery of wilderness. This produced a new type of citizen - one with the power to tame the wild and one upon whom the wild had conferred strength and individuality.[1] His essays are collected in The Significance of the Frontier in American History, which won the Pulitzer Prize for History in 1933. Turner's sectionalism thesis had almost as much influence among historians as his frontier thesis. He argued that different ethno-cultural groups had distinct settlement patterns, and this revealed itself in politics, economics and society. Frederick Jackson Turner married Caroline Mae Sherwood in Chicago in November 1889. They had three children: Dorothy Kinsley Turner (later Main), who lived to give them grandchildren; Jackson Allen Turner, who died in October 1899 and Mae Sherwood Turner, who died in February 1899. One of Main's grandchildren was historian Jackson Turner Main (1917–2003), a scholar of Revolutionary America. Frederick Jackson Turner died in 1932 in California where he had been a research associate at the Huntington Library.[2] A White · Bancroft · Winsor · Poole · CK Adams · Jay · Henry · Angell · H Adams · Hoar · Storrs · Schouler · Fisher · Rhodes · Eggleston · CF Adams · Mahan · Lea · Smith · McMaster · Baldwin · Jameson · G Adams · Hart · Turner · Sloane · Roosevelt · Dunning · McLaughlin · Stephens · Burr · Ford · Thayer · Channing · Jusserand · Haskins · Cheyney · Wilson · Andrews · Munro · Taylor · Breasted · Robinson · Greene · Becker · Bolton · Beard · Dodd · Rostovtzeff · McIlwain · Ford · Larson · Ferguson · Farrand · Thompson · Schlesinger · Neilson · Westermann · Hayes · Fay · Wertenbaker · Latourette · Read · Morison · Schuyler · Randall · Gottschalk · Curti · Thorndike · Perkins · Langer · Webb · Nevins · Bemis · Bridenbaugh · Brinton · Boyd · Lane · Nichols · Holborn · Fairbank · Woodward · Palmer · Potter · Cochran · L White · Hanke · Wright · Morris · Gibson · Bouwsma · Franklin · Pinkney · Bailyn · Craig · Curtin · Link · McNeill · Degler · Davis · Iriye · Harlan · Herlihy · Leuchtenburg · Wakeman · Tilly · Holt · Coatsworth · Bynum · Appleby · Miller · Darnton · Foner · Louis · Hunt · McPherson · Spence · Sheehan · Kerber · Weinstein · Spiegel
