Mary Cassatt

She was described by Gustave Geffroy as one of "les trois grandes dames" (the three great ladies) of Impressionism alongside Marie Bracquemond and Berthe Morisot. In 1879, Diego Martelli compared her to Degas, as they both sought to depict movement, light, and design in the most modern sense. She also played an important role in introducing Impressionism to American collectors, notably through her friendship with the Havemeyer family. Provided by Wikipedia
