In 1969, the Museum appointed its first curator in the Department of Painting and Sculpture to be responsible for objects defined by time period. That year John L. Tancock became Associate Curator of 19th and 20th Century Sculpture. During the several years prior, Henry G. Gardiner and Allen Staley both served under the general title of Assistant Curator. In 1971 Anne d'Harnoncourt joined the department as its first Associate Curator of 20th Century Painting. In 1973, Twentieth Century Art became a separate department, with d"Harnoncourt as curator. Mark Rosenthal succeeded her in 1983 when the Museum named d'Harnoncourt its George D. Widener Director. In 1989 Ann Temkin joined the Museum as Acting Curator of Twentieth Century Art, and the following year she was appointed the Muriel and Philip Berman Curator of Twentieth Century Art. The final departmental name change occurred in the year 2000. To reflect the coming millenium, the Twentieth Century Art Department became the Department of Modern and Contemporary Art. It continues to operate as such.
