“In the 1870s Whistler painted full length portraits of F.R. Leyland and his wife. Leyland subsequently commissioned the artist to decorate his dining room; the result was Whistler’s Harmony in Blue and Gold: The Peacock Room, now in the Freer Gallery of Art. The room was designed and painted in a rich and unified palette of brilliant blue-greens with over-glazing and metallic leaf, and is considered a high example of the Anglo-Japanese style. The painting was inspired by the blue and white china copied in watercolor for Sir Henry Thompson’s catalogue, and from the porcelain both he and Leyland collected.
Artist and patron quarreled so violently over the room and the proper compensation for the work that their relationship was terminated. At one point, Whistler gained access to Leyland’s home and painted two fighting peacocks meant to represent the artist and his patron; one holds a paint brush and the other holds a bag of money. The entire room was later purchased by industrialist and aesthete Charles Lang Frier, and installed in his collection. The published communications between Freer and Whistler reveal how Whistler’s interest in those collecting his work in his native country (the United States) evolved over many decades.”
