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.

Hambourg, Jan (1882-1947). Russian-born violinist; Isabelle McClung’s husband. Hambourg moved with his family to Toronto, Ontario, in 1910, where he was the head of the violin department at the Hambourg Conservatory and performed as part of the Hambourg Trio. He married Isabelle McClung in April 1916. Cather reacted negatively to both Hambourg and the marriage, but she gradually came to accept him. Beginning in the 1920s, Hambourg left the family conservatory and focused on solo violin performance in Europe. Cather enjoying long visits with Isabelle and Jan in Toronto in 1921 and France in 1923 and 1935. She dedicated The Professor’s House (1925) to him (“For Jan, because he likes narrative”) and asked him to make musical corrections to Lucy Gayheart (1935). When Isabelle died, Jan sent to Cather the three hundred letters from Cather to Isabelle in his possession, and Cather destroyed them.
