The Whitney’s collection includes over 22,000 works created by more than 3,000 artists in the United States during the twentieth and twenty-first centuries. At its core are Museum founder Gertrude Vanderbilt Whitney’s personal holdings, totaling some 600 works when the Museum opened in 1931. These works served as the basis for the founding collection, which Mrs. Whitney continued to add to throughout her lifetime. The founding collection reflects Mrs. Whitney’s ardent support of living American artists of the time, particularly younger or emerging ones, including Peggy Bacon, George Bellows, Stuart Davis, Charles Demuth, Mabel Dwight, Edward Hopper, Yasuo Kuniyoshi, Reginald Marsh, and John Sloan. This focus on the contemporary, along with a deep respect for artists’ creative process and vision, has guided the Museum’s collecting ever since.
