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.

Mackenzie, Cameron (1882 -1921). American magazine editor and journalist. Born in Wilkes-Barre, PA, Cameron Mackenzie graduated from the Lawrenceville School, which his father founded, and studied at Yale University for a year before enrolling in the New York University Law School, from which he graduated in 1907. In 1907 he also married Elizabeth McClure, daughter of S. S. McClure. His father-in-law put him on the editorial staff of McClure’s Magazine, where he worked with Cather. In 1912 he and Frederick Collins wrested control of the magazine from S. S. McClure. Mackenzie resigned from McClure’s in 1915, subsequently writing two novels and serving as a correspondent for the London Morning Post during World War I. He died unexpectedly of pneumonia on board the Cunard liner Aquitania shortly after the ship departed London for New York City.
