Whitney, New York

Whitney Museum houses one of the world's foremost collections of twentieth-century American art. The Permanent Collection of some 12,000 works encompasses paintings, sculptures, multimedia installations, drawings, prints, and photographs--and is still growing.

The Museum was founded in 1931 with a core group of 700 art objects, many of them from the personal collection of founder Gertrude Vanderbilt Whitney; others were purchased by Mrs. Whitney at the time of the opening to provide a more thorough overview of American art in the early decades of the century.
