Henderson, Alice Corbin (1881-1949). American poet and editor. Alice Corbin published her first volume of poetry in 1898, when she was seventeen. She attended the University of Chicago, then rented a studio in the Fine Arts Building, where she met artist William Penhallow Henderson, whom she married in 1905. She worked with Harriet Monroe at Poetry magazine even after moving to Santa Fe, NM, in 1916. Both Hendersons became dedicated to Native American and Southwest cultures. Alice Henderson edited a collection of poems about New Mexico, The Turquoise Trail (1928), for which she asked Cather’s permission to reprint “Spanish Johnny.”

Knopf, Alfred A. (1892-1984). President of New York publisher Alfred A. Knopf, Inc. Knopf received his BA from Columbia University in New York City in 1912 and founded Alfred Knopf, Inc., in 1915 with his future wife Blanche Wolf. They married in 1916, and their son Alfred “Pat” Knopf was born in 1918. Cather chose him as her publisher beginning with Youth and the Bright Medusa (1920) and One of Ours (1922), partly because she was dissatisfied with the promotion of her books by Houghton Mifflin but also because she recognized the high quality of Knopf's books, as well as what she regarded as his intelligent advertising. Knopf was noted for publishing the work of leading European and South American writers in translation, as well as original works. Knopf and Cather’s extensive correspondence testifies to their mutual professional respect and to what also became an important personal friendship.
