She resumed her career after a stint in Italy, eventually moving back to Paris and working again with Impressionist artists. Eleven of her paintings were exhibited at an Impressionist show in 1879, at which time Cassatt catapulted to artistic fame.
Cassatt eventually began to favor more simplistic painting and faded away from the Impressionist movement. Her eyesight declined after 1910, and devoted time to ensuring art, including her own, ended up in exhibits and collections. Her works are dispersed throughout the United States and in Europe. She died and was buried in France in 1926. She is remembered as a pioneer of Impressionism and her lovely, intimate depictions of women and children.
On the 160th anniversary of her birth, May 22, 2004, a historical marker was dedicated to Cassatt in Pittsburgh, near the location of where she was born. A small garden was also planted in her honor near the marker. Her birthplace, where she lived until age 4, was originally located on Rebecca St. which was changed to Reedsdale St. after Allegheny City was absorbed by the city of Pittsburgh in 1907. The Cassatt family left the Pittsburgh area for Eastern Pennsylvania in 1849.
