Mary Cassatt. Mary Stevenson Cassatt was an American painter and printmaker.
   She was born in Allegheny City, Pennsylvania, but lived much of her adult life in France, where she first befriended Edgar Degas and later exhibited among the Impressionists. Cassatt often created images of the social and private lives of women, with particular emphasis on the intimate bonds between mothers and children.
   She was described by Gustave Geffroy in 1894 as one of les trois grandes dames 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.
   Cassatt was born in Allegheny City, Pennsylvania, which is now part of Pittsburgh. She was born into an upper-middle-class family: Her father, Robert Simpson Cassat, was a successful stockbroker and land speculator.
   He was descended from French Huguenot Jacques Cossart, who came to New Amsterdam in 1662. Her mother, Katherine Kelso Johnston, came from a banking family. Katherine Cassatt, educated and well-read, had a profound influence on her daughter. To that effect, Cassatt's lifelong friend Louisine Havemeyer wrote in her memoirs: Anyone who had the privilege of knowing Mary Cassatt's mother would know at once that it was from her and her alone that inherited her ability. The ancestral name had been Cossart. A distant cousin
