3rd Thursdays @ 3: Stieglitz and His Artists: Matisse to O’Keeffe. Join Ines Powell for an overview of this Metropolitan Museum of Art exhibition, the first large-scale presentation of paintings, sculptures, drawings, and prints from Alfred Stieglitz’s collection, acquired by the Metropolitan in 1949. In addition to being a master photographer, Stieglitz (1864–1946) was a visionary promoter of modern American and European art, who assembled a vast art collection of exceptional breadth and depth. Through a succession of influential galleries that he ran in New York City between 1905 and 1946, Stieglitz exhibited many of the most important artists of the era, and he collected works by Pablo Picasso, Henri Matisse, Constantin Brancusi, Gino Severini, Wassily Kandinsky, Georgia O’Keeffe and others. For more than sixty years, the Alfred Stieglitz Collection has been the cornerstone of the Museum’s holdings of modern American art. The exhibition runs through January 2. 3 p.m.
