Sergeant, Elizabeth Shepley (1881-1965). American journalist and author. Born and raised in Winchester, MA, a suburb of Boston, Elizabeth Sergeant graduated from Bryn Mawr College in 1903. In 1910, Pauline Goldmark sent her to Cather at McClure’s Magazine with a proposed article, published as “Toilers of the Tenements,” and Cather and Sergeant became lifelong friends. In 1914 Sergeant became one of the original contributors to the New Republic. While on assignment in France in 1917 she was injured by a land mine; her injury and recuperation were the subject of Shadow-Shapes: Journal of a Wounded Woman (1920). She moved to New Mexico in 1920 and became involved with the Taos artists colony and advocated for Native American rights, but her work frequently took her back to New York City. She included Cather in her collection of portraits of prominent Americans, Fire under the Andes (1927). Sergeant studied with Carl Jung and Toni Woolf in Zurich, Switzerland, from 1929 to 1931. When she returned to the U.S. she sold her house in New Mexico and settled in New York City, writing many magazine articles about authors and psychological topics. She later moved to Rockland County, NY. Cather’s letters to Sergeant comment frequently on both her own and Sergeant’s writing and testify to a strong and lively friendship maintained despite Sergeant's being a committed reformer and far to the left of Cather politically and culturally. Sergeant’s Willa Cather: A Memoir (1953) includes extensive paraphrases of Cather’s letters to her.

Cather, Charles Douglas (1880-1938) (“Douglass”). Cather’s brother. Born in Virginia and raised in Red Cloud, NE, Charles was third child and second son of Charles and Virginia Cather. As an adolescent, Douglass Cather helped his father supervise rented farm properties and worked as a messenger for the local Burlington & Missouri Railroad office. In 1897 he left Red Cloud for a position in Sterling, CO, and then took a position with at the Cheyenne, WY, office of the Burlington Railroad. In 1908 he traveled to Mexico, an experience that his sister gave to Emil Bergson in O Pioneers! (1913). By 1910 he was working for the Santa Fe railroad and living in Winslow, AZ, where Willa Cather visited him in 1912. He later achieved success in the oil business in California. Although he never married, Cather notes that during the last six or seven years of his life he had a relationship with Dorothy Rogers. Douglass visited Cather in New York City in December of 1937. His death in June 1938 left her devastated. Douglass served as a prototype for one of the twin brothers in the Templeton family in “Old Mrs. Harris” (1932) and Hector the messenger boy brother in “The Best Years” (1948). His years working for the Burlington also inspired Cather’s many railroad worker characters in her novels, including Song of the Lark (1915) and The Professor’s House (1925). Few letters from this important sibling relationship have survived.
