The sitter (3 November 1915 – 4 January 1998) was born in Tuxedo Park and was the second daughter of J. Insley Blair Jr (1876-1939) and Natalie Bennett Knowlton (1887-1951), an important collector of Americana, and the first woman of the first rank to do so. Her husband had a railroad and banking fortune. The Blairs lived at Tuxedo Park in a Carrère and Hastings mansion called Blairhame, that was donated to Tuxedo Park School in 1957 by Joan Blair Overton. Her older sister was Natica Blair (1913-1955), later Mrs Screven Lorillard who sadly shot herself after an illness.
