About the author

Born in Louisville, Kentucky, in 1863, Ellen Churchill Semple studied at Vassar College and later pursued advanced study in Germany, where she was influenced by the geographer Friedrich Ratzel. She went on to become one of the best-known American geographers of her era, writing and lecturing on the ways place, landscape, and environment shape human societies.

Semple played a major role in the early development of human geography in the United States. She taught at the University of Chicago and later at Clark University, and in 1921 she became the first female president of the Association of American Geographers. Her books, including American History and Its Geographic Conditions and Influences of Geographic Environment, were especially influential with students and scholars in the early twentieth century.

Today, Semple is remembered both for her importance as a trailblazing woman in academic geography and for the controversy surrounding some of her ideas. Her writing helped define an emerging discipline, even as later scholars strongly challenged the environmental determinism associated with her work.
