Louisine Waldron Havemeyer, née Elder, was an American patron and collector. In 1883 she married the collector Henry Osborne Havemeyer, the ex-husband of her aunt.
Havemeyer met Mary Cassatt at the age of 20 and through her was introduced to the work of the French Impressionists. She went on to buy works by Edgar Degas, Claude Monet, Camille Pissarro and Cassatt herself.
In 1901 she began collecting the works of Cézanne. From 1879 until 1881 she was in correspondence with Whistler. She questioned the realism of Whistler's portrait of Théodore Duret, Arrangement en couleur chair et noir: Portrait de Théodore Duret y252, considering the pink domino to be a decorative but inappropriate accessory.
In 1882 Whistler selected five Venice pastels for Havemeyer for £30. These were probably Sunset, in red and brown m0743, Campo Sta. Marta - Winter Evening m0753, Winter Evening m0755, The Steps m0786 and Nocturne - San Giorgio m0803. She later gave them to C. L. Freer in January 1917. The Palace; white and pink m0758, Grey and Silver - The Beach - Holland m0964, Grey and Green - Dordrecht m0976 and Variations in violet and rose m1079 were bought by Havemeyer's husband and bequeathed to her at his death in 1907.
At her own death Havemeyer's collection was bequeathed by herself and her children to the Metropolitan Museum of Art in New York and to the National Gallery of Art in Washington DC.
