Frederick Jackson Turner (1861-1932) was an American historian. He was a professor of history at the University of Wisconsin (1890-1910) and Harvard (1910-1922). He is best known for this work on the frontier in American history in which he emphasized the importance of the frontier in shaping the American character. The work was first published on July 12, 1893, in a paper read in Chicago to the American Historical Association during the Chicago World's Fair.

Frederick Jackson Turner's 1893 essay on the history of the United States remains one of the most famous and influential works in the American canon. That is a testament to Turner's powers of creative synthesis; in a few short pages, he succeeded in redefining the way in which whole generations of Americans understood the manner in which their country was shaped, and their own character moulded, by the frontier experience. It is largely thanks to Turner's influence that the idea of America as the home of a sturdily independent people – one prepared, ultimately, to obtain justice for themselves if they could not find it elsewhere – was born. The impact of these ideas can still be felt today: in many Americans' suspicion of "big government," in their attachment to guns – even in Star Trek's vision of space as "the final frontier." Turner's thesis may now be criticised as limited (in its exclusion of women) and over-stated (in its focus on the western frontier). That it redefined an issue in a highly impactful way – and that it did so exceptionally eloquently – cannot be doubted.

Frederick Jackson Turner (November 14, 1861 - March 14, 1932) was an American historian in the early 20th century, based at the University of Wisconsin until 1910, and then at Harvard. He was primarily known for his "Frontier Thesis." He trained many PhDs who came to occupy prominent places in the history profession. He promoted interdisciplinary and quantitative methods, often with a focus on the Midwest. He is best known for his essay "The Significance of the Frontier in American History", whose ideas formed the Frontier Thesis. He argued that the moving western frontier shaped American democracy and the American character from the colonial era until 1890. He is also known for his theories of geographical sectionalism. In recent years historians and academics have argued strenuously over Turner's work; all agree that the Frontier Thesis has had an enormous impact on historical scholarship and the American soul.
