Frederick Jackson Turner

Frederick Jackson Turner, born in Portage, Wisconsin on November 14, 1861, and dying on March 14, 1932, was a prominent American historian who spent the first part of his career at the University of Wisconsin-Madison before moving to Harvard University in 1910. His lasting fame rests on the frontier thesis, but he also shaped the field by training numerous PhDs who became notable historians themselves. Turner pushed for interdisciplinary and quantitative approaches in history, with a particular focus on the Midwest.

Turner’s central idea, laid out in his essay “The Significance of the Frontier in American History,” argued that the ever-moving western frontier had a powerful effect on American democracy and the national character from colonial times up to 1890. He also developed theories about geographical sectionalism. While later historians have debated his work extensively, there is broad agreement that his frontier thesis had a massive impact on historical scholarship.

Growing up in Portage, Wisconsin, Turner came from a middle-class family. His father, Andrew Jackson Turner, was a Republican activist, railroad investor, and newspaper editor, while his mother, Mary Olivia Hanford Turner, was a teacher. Turner was deeply influenced by the nature-focused writings of Ralph Waldo Emerson, as well as scientists like Charles Darwin, Herbert Spencer, and Julian Huxley, and the field of cartography. He earned his undergraduate degree from the University of Wisconsin in 1884, where he was a member of the Phi Kappa Psi fraternity, and later completed his PhD in history at Johns Hopkins University in 1890. His dissertation, supervised by Herbert Baxter Adams, examined the fur trade in Wisconsin and was titled *The Character and Influence of the Indian Trade in Wisconsin*.

Turner was not a prolific publisher; his influence came from concise, interpretive theories in his articles, which inspired hundreds of followers. His two most important ideas were the Frontier Thesis and the Sectional Hypothesis. Despite publishing little, his encyclopedic knowledge of American history made him, by 1910, one of the two or three most influential historians in the country. He was skilled at promoting both his ideas and his students—such as Merle Curti and Marcus Lee Hansen—helping them secure positions at major universities. He circulated his essays and lectures among key scholars and writers, published widely in magazines, and reused his favorite material to reach the largest possible audience. Within the American Historical Association, he held influential roles and advised *The American Historical Review*. His focus on the frontier’s role in shaping American character shaped thousands of scholarly histories. By the time of his death in 1932, 60% of major U.S. history departments offered courses on frontier history aligned with his theories.

Frustrated by university regents who wanted less research and more teaching and public service, Turner sought a place where he could focus on research. He turned down offers from the University of California and accepted a position at Harvard in 1910, staying until 1922. He was succeeded there in 1924 by Arthur M. Schlesinger, Sr. Turner was elected to the American Antiquarian Society in 1907 and became a fellow of the American Academy of Arts and Sciences in 1911. He never felt entirely at home at Harvard, and after retiring in 1922, he became a visiting scholar at the Huntington Library in Los Angeles. There, his note cards and files kept growing, though he published few monographs. His 1920 book *The Frontier in American History* was a collection of older essays. During his time at Wisconsin (1890–1910) and Harvard (1910–1922), he trained many disciples who went on to dominate American history programs nationwide. His model of sectionalism—viewing it as a mix of social forces like ethnicity and land ownership—encouraged historians to use social history to analyze economic, political, and social developments. He also collaborated with J. Franklin Jameson on major projects for the American Historical Association.

Turner’s theories fell out of favor in the 1960s, when critics argued he neglected regionalism and overstated the egalitarianism and democracy of a frontier that was often restrictive for women and minorities. After his death, his former colleague Isaiah Bowman remarked that Turner’s ideas lacked evidence from field studies and that he relied on documents and general impressions rather than firsthand observation. Still, his ideas were never forgotten and even influenced the emerging field of environmental history. Turner gave a strong push to quantitative methods, and later scholars using new statistical techniques have confirmed many of his claims about population movements. He himself believed that no single method of historical interpretation was sufficient, given his own biases and the conflicting evidence, so he advocated for an interdisciplinary approach as the most accurate way to understand history.

Turner’s frontier thesis first appeared in a scholarly paper, “The Significance of the Frontier in American History,” which he read before the American Historical Association in Chicago during the World’s Columbian Exposition in 1893. He argued that the spirit and success of the United States were deeply tied to the frontier experience.
