This lavishly illustrated, bilingual art book presents drawings by Ramón Casas in the Charles Deering McCormick Library of Special Collections at the Northwestern University Library and oil paintings by Casas from private collections and the Art Institute of Chicago. Charles Deering and Ramón Casas follows the development and dramatic dissolution of a three-way friendship that connected the Spanish painter Ramón Casas (1866–1932); the Chicago industrialist Charles Deering (1852–1927), who was a collector and admirer of Casas’s work as well as a patron of Northwestern University; and the Spanish artist Miguel Utrillo (1862–1934), Casas’s lifelong friend and the father of the French painter Maurice Utrillo. Casas introduced Deering to Sitges, a beach town near Barcelona, Spain, where the latter created a palatial estate with a museum to house his art collection. Miguel Utrillo served as director of the museum. The text explores the treasures housed at Maricel and what happened among the three men that led Casas to abandon Utrillo and Deering to depart Spain, taking his art collection with him.
