Question: Which modernist sculptor is younger, Joseph Csaky or Jean Arp? Passage:In 1953, the foundation's collecting criteria expanded under its new director, James Johnson Sweeney. Sweeney rejected Rebay's dismissal of "objective" painting and sculpture, and he soon acquired Constantin Brancusi's Adam and Eve (1921), followed by works of other modernist sculptors, including Joseph Csaky, Jean Arp, Calder, Alberto Giacometti and David Smith. Sweeney reached beyond the 20th century to acquire Paul Cezanne's Man with Crossed Arms (c. 1899). The same year, the foundation also received a gift of 28 important works from the Estate of Katherine S. Dreier, a founder of America's first collection to be called a modern art museum, the Societe Anonyme. Dreier had been a colleague of Rebay's. The works included Little French Girl (191418) by Brancusi, an untitled still life (1916) by Juan Gris, a bronze sculpture (1919) by Alexander Archipenko and three collages (191921) by German Hanoverian Dadaist Schwitters. It also included works by Calder, Marcel Duchamp, El Lissitzky and Mondrian. Among others, Sweeney also acquired the works of Alberto Giacometti, David Hayes, Willem de Kooning and Jackson Pollock.
