Bessie Louise Pierce was an influential American historian renowned for her comprehensive three-volume work, A History of Chicago. Born in Caro, Michigan, and raised in Waverly, Iowa, she pursued her education at the University of Iowa, where she earned her bachelor's degree, followed by a master's degree from the University of Chicago in 1918. Her academic career began at the University of Iowa under the mentorship of Arthur M. Schlesinger, Sr., who encouraged her to pursue a doctorate. In 1929, she was invited back to the University of Chicago to lead the History of Chicago project, a significant undertaking that would define her legacy. Pierce's most notable contributions to historical scholarship include her detailed volumes on Chicago's past, with the first two published in 1937 and 1940, and the third completed in 1957 after her retirement. Her work not only chronicled the city's development but also offered insights into its cultural and social dynamics. In addition to A History of Chicago, she authored As Others See Chicago: Impressions of Visitors, 1673–1933 for the Century of Progress in 1933. Pierce's scholarship earned her a Guggenheim Fellowship in 1955, reflecting her impact on the field of history. Although she began a fourth volume covering 1894 to 1915, it remained unfinished. She returned to Iowa in her later years and passed away in 1974, leaving behind a significant legacy in American historical writing.
