Lesser, Joseph (1901-1989). Treasurer of Alfred A. Knopf, Inc. Born in Poland, Joseph Lesser immigrated to the U.S. with his family in 1906, and he became a naturalized American citizen. He and his wife, Eva, and their children lived in Brooklyn, NY. He served for many years as treasurer of Alfred A. Knopf, Inc. His office prepared Cather’s tax returns for her, and in her will Cather named him as a potential successor to Edith Lewis as her literary executor. Lesser died in Hallandale, FL.

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.
