Fields, Annie Adams (1835-1915). Literary hostess, author, and social reformer. At age 20, Annie Adams married James T. Fields, partner in the Boston publishing house of Ticknor & Fields. Both before and after her husband’s death in 1881, Fields often entertained important American, British, and European authors at her home at 148 Charles Street in Boston, MA. After James’ death, Sarah Orne Jewett, whose books were published by Ticknor & Fields, began sharing Annie’s homes at 148 Charles Street and Manchester-on-the-Sea, MA. Cather met Fields in Boston in 1908, a meeting Cather described in "The House on Charles Street," an essay reviewing Memories of a Hostess (a volume of selections from Fields' journals, 1922). A revised version of this essay, retitled "148 Charles Street," appeared in Not Under Forty (1936). After Jewett’s death in 1909, Fields edited The Letters of Sarah Orne Jewett (1911), which included several letters to Cather. Fearing that 148 Charles Street would become a museum after her death, Fields requested that it be torn down.

Jewett, Sarah Orne (1849-1909). American short story writer and novelist. Born in South Berwick, ME, Jewett began sharing homes in Boston (at 148 Charles Street) and Manchester-on-the-Sea, MA, with Annie Adams Fields in 1881, while continuing to live in her family home in South Berwick with her mother and sister part of the year. She was associated throughout her career with the Atlantic Monthly, and her best-known work, The Country of the Pointed Firs, was serialized there in 1896. Like much of her fiction, it focused on rural and small town New England life. By the time Cather met Jewett at 148 Charles Street in 1908, Jewett had largely ceased writing because of a spinal concussion she suffered in a 1902 carriage accident. She wrote important letters of advice to Cather in 1908, criticizing her decision to write "The Gull's Road" (1908) from the perspective of a male character, which she called "something of a masquerade" (27 Nov. 1908), and urging her to give up her editorial work at McClure's Magazine so she could focus full-time on fiction writing (13 Dec. 1908). After Jewett's death in South Berwick in 1909, Cather often referred to her and her advice about writing. Cather edited The Best Stories of Sarah Orne Jewett (1925) for publisher Houghton Mifflin, and in her preface classed The Country of the Pointed Firs with Mark Twain's Huckleberry Finn and Nathaniel Hawthorne's The Scarlet Letter as one of "three American books which have the possibility of a long, long life."

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.
