Mrs Chapman was the wife of Alfred Chapman, a Liverpool engineer and industrialist, whose brothers and sisters (Ellen, George and Dr Chapman) Whistler knew.
Alfred Chapman worked at the Phoenix foundry in Liverpool. He and his wife may have met Whistler through the Liverpool shipping magnate F. R. Leyland. They became one of Whistler's major patrons in the 1870s, buying Nocturne: Blue and Silver - Bognor (YMSM 100), Nocturne: Blue and Gold - Southampton Water (YMSM 117), Blue and Gold: Channel (YMSM 159), Nocturne: Battersea Reach (YMSM 160), Cremorne (YMSM 168) and Nocturne: Grey and Gold - Chelsea Snow (YMSM 174). In the late 1880s and early 1890s the Chapmans were living in and around Brighton and were still in contact with Whistler. They agreed to lend Nocturne: Grey and Gold - Chelsea Snow (YMSM 174) to the III Internationale Kunst-Austellung in Munich in 1888 and Nocturne: Blue and Silver - Bognor (YMSM 100) to the Exposition Internationale de Peinture et de Sculpture at the Galerie Durand-Ruel in Paris in the same year.
