"According to Mr. Phipps Jr., his father (in consultation with his uncle, John S. Phipps, a violin collector) purchased the instrument in 1943 for his musically gifted son from Mr. Bennett's widow, Katherine D. Bennett. (According to an announcement from the American Art Association's Anderson Galleries in New York, Mr. Bennett's entire collection was put up for sale in 1932, but in light of Mr. Phipps's account, the instrument was presumably not sold."
