Greenslet, Ferris (1875-1959). American editor and writer. Born in Glens Falls, NY, Ferris Greenslet earned a BA (1897) from Wesleyan University and a PhD (1900) from Columbia University. He served as associate editor at the Atlantic Monthly from 1902 to 1907, and married Ella Stoothoff Hulst in 1903; they had two children, Marguerite (born 1904) and George (born 1906). As an author he specialized in biography. He became literary editor at Houghton Mifflin, the Boston publisher of the Atlantic, c. 1908 and was socially and professionally acquainted with Annie Adams Fields and Sarah Orne Jewett, who may have introduced him to Cather. He evidently solicited Cather to submit Alexander’s Bridge (1912), her first published novel, to Houghton Mifflin. In 1910, when Greenslet became editor in chief of the trade department, Roger Scaife divided his shares as a director of the company with him, and the two presented themselves to authors as partners, with Scaife handling book advertising and format and Greenslet negotiating contracts and supervising editing; when Greenslet was absent from the office, Scaife handled correspondence with Cather. Greenslet became a director of Houghton Mifflin in 1919 and manager of the trade department in 1933. Cather left Houghton Mifflin as a publisher for Alfred A. Knopf, Inc., because she became dissatisfied with the production and advertising of her books. However, she remained on cordial terms with Greenslet and undertook several projects for him after her departure. Her extant letters to him constitute one of the largest groups to a single correspondent.

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.
