Joan Mitchell (1925–1992) established a singular visual vocabulary over the course of her more than four decade career. Born in Chicago and educated at the School of the Art Institute of Chicago, from which she received a BFA (1947) and an MFA (1950), Mitchell moved to New York in 1949 and was an active participant in the downtown arts scene. She began splitting her time between Paris and New York in 1955, before moving permanently to France in 1959. In 1968, Mitchell settled in Vétheuil, a small village northwest of Paris, while continuing to exhibit her work throughout the United States and Europe. When Mitchell passed away in 1992, her will specified that a portion of her estate should be used to establish a foundation to directly support visual artists.
