The Mary Cassatt Catalogue Raisonné project is actively engaged in updating and expanding the existing catalogue by Adelyn Dohme Breeskin. Based on Breeskin's pioneering research and her archives, the Mary Cassatt Catalogue Raisonné will include new works that have come to light since the publication of the first catalogue in 1970. The Cassatt Committee (comprised of Warren Adelson, Jay Cantor, William Gerdts and Pamela Ivinski) will review all existing attributions to Cassatt as well as reconsider the chronology of Cassatt's work. New titles, exhibition histories as well as provenance information will be included. The project will produce a revised and enlarged catalogue raisonné, including both the original essays and new scholarship.
