Walt Whitman to Mary Whitall Smith Costelloe, 4 August 1888

Correspondent:
Mary Whitall Smith Costelloe (1864–1945) was a political activist, art historian, and critic, whom Whitman once called his "staunchest living woman friend." A scholar of Italian Renaissance art and a daughter of Robert Pearsall Smith, she would in 1885 marry B. F. C. "Frank" Costelloe. She had been in contact with many of Whitman's English friends and would travel to Britain in 1885 to visit many of them, including Anne Gilchrist shortly before her death.
