McClure, Samuel Sidney (1857-1949) (“S.S.”). Irish-born American publisher. McClure immigrated to the U.S. at age nine, living with his family in Indiana. Despite poverty and the limited education he had received in Ireland, he graduated from high school and then Knox College in Illinois. He then moved to Boston, MA, where from 1882 to 1884 he edited the Wheelman, a bicycling magazine. Despite opposition from her parents, he married his Knox College classmate Harriet Hurd in 1883. The couple had four biological children (Eleanor, Bess, Mary, and Robert), and adopted one (Enrico). In 1884, S.S. started McClure’s Syndicate, which placed fiction in newspapers across the country. In 1893 with his college classmate John Sanborn Phillips he started McClure's Magazine, which was best-known for the "muckraking" exposés by writers such as Ida Tarbell and Lincoln Steffens, but which also published literature. After his cousin H.H. McClure, who worked for the McClure Syndicate, brought Cather to S.S. McClure’s attention, McClure, Phillips & Co. brought out Cather’s first book of fiction, The Troll Garden (1905). When most of the editorial staff, including Steffens and Tarbell, resigned from McClure’s in 1906, he hired Cather as an editor; she later became managing editor. After she left her position at McClure’s in 1912 and when S. S. McClure had lost control of the magazine still bearing his name, Cather ghost wrote his autobiography (McClure’s serial 1913-1914, book publication 1914). McClure made repeated—and ultimately failed—attempts to reestablish himself in journalism and magazine publishing, often trying to enlist Cather in these enterprises. She almost went with him to Europe in 1915 to report on the war for the Evening Mail, and she remained personally loyal to her mercurial and often-irresponsible former employer. He served as the prototype for Marcus O’Mally, editor of the Outcry, in her story “Ardessa” (1918), and it has been suggested that Cather modeled the courtship and marriage between Myra and Oswald Henshaw in My Mortal Enemy (1926) on that of the McClures.

Lewis, Edith Labaree (1881-1972). Magazine editor, advertising copywriter, and Cather's domestic partner. Born in Lincoln, NE, to Henry Euclid Lewis and Lillie Gould Lewis, Edith Lewis attended the preparatory school associated with the University of Nebraska, earning college credits from the University before transferring to Smith College in Northampton, MA, in 1899. She received an A.B. in English from Smith in 1902 and returned home to teach elementary school. She met Willa Cather in the summer of 1903 at the home of Sarah Harris, publisher of the Lincoln Courier. Moving to New York City soon afterward, Lewis settled into a studio on Washington Square and found work at the Century Publishing Company. Cather was her guest when she visited the city from Pittsburgh. In 1906, at Cather's suggestion, Lewis applied for a position as an editorial proofreader at McClure's Magazine, and the two women worked together on the McClure's staff for six years. In 1908, they moved into a shared apartment at 82 Washington Place, and then, in 1912, to Five Bank Street. Lewis left McClure's in 1915 to become managing editor of Every Week Magazine, where she stayed until the magazine folded in 1918. In 1919 she began a long career as an advertising copywriter at the J. Walter Thompson Co. In 1926 Edith Lewis acquired the land on which she and Cather built their cottage on Grand Manan Island. When they lost their apartment on Bank Street to subway construction in 1927, they shared quarters at the Grosvenor Hotel when they were both in New York City. In 1932 they took an apartment at 570 Park Avenue. Throughout their relationship, Lewis was closely involved in Cather's creative process, reading and editing her work in pre-publication forms. Cather's will appointed Lewis as executor of her literary estate and a beneficiary of her literary trust. Lewis authorized E.K. Brown as Cather's first biographer and published her own memoir of Cather, Willa Cather Living (1953). She remained in their Park Avenue apartment after Cather's death and died there after a long period of illness and invalidism. She is buried at Cather's side in Jaffrey, NH.
