Hambourg, Isabelle McClung (1877-1938). Cather’s longtime friend. Cather met Isabelle McClung, the daughter of a socially prominent, Pittsburgh (PA) family, in 1899 in the dressing room of actress Lizzie Hudson Collier. McClung seems to have been the first woman to reciprocate Cather’s romantic affections. In 1901, McClung invited Cather to live in her family’s large home in the Squirrel Hill neighborhood of Pittsburgh. She and Cather traveled together to Europe in 1902, and McClung accompanied Cather on a visit home to Nebraska in 1905. After Cather moved to New York City in 1906, she frequently visited McClung in Pittsburgh, finding the familiar house a congenial place to write, and McClung visited New York City, staying with Cather and Edith Lewis. Cather and McClung also rented a vacation cabin in Cherry Valley, NY, in 1911, and traveled together to Virginia in 1913. In late 1915, shortly after the death of her father, Judge Samuel McClung, Isabelle announced her intention to marry violinist Jan Hambourg. Cather reacted negatively to the marriage (which took place in 1916) but eventually reconciled herself to it, enjoying long visits with the Hambourgs in Toronto, Ontario, in 1921 and France in 1923 and 1935. Cather and Edith Lewis also spent time with the Hambourgs in Paris is 1930 and 1935. The latter trip occurred after Isabelle sought treatment in the U.S. for the kidney disease that killed her several years later in Italy. Her death came only four months after Cather’s brother Douglass died, leaving her feeling bereft. “No other living person cared as much about my work, through thirty-eight years,” she wrote her brother Roscoe (#2137). After Isabelle’s death, Jan sent to Cather the six hundred letters from Cather to Isabelle in his possession, and Cather destroyed them, although a few letters from Isabelle and Cather postcards to Isabelle are extant.

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.

Nichols, Marian Clarke (1874-1963). American activist. Marian Clarke Nichols was born in Boston, MA, to Elizabeth Homer Nichols and Arthur Howard Nichols. She graduated from Radcliffe College and continued her education for an additional term at the University of Cambridge. Nichols spent most of her adult life advocating for women’s and working-class rights, often participating in marches and lobbying for legislative reform in the Massachusetts State House. She also worked as a special examiner for the U.S. Civil Service Commission and served as the chair of the Civil Service Department of the Massachusetts Federated Women’s Clubs. In 1920 she ran unsuccessfully as an independent candidate for Ward 8 of the Massachusetts legislature with the slogan “Public Office is a Public Trust,” becoming one of the first women to run for office in Massachusetts.
