Level 3 explores 20th-century art through the mid-1970s. The Lane Collection of early modernist paintings and works on paper by Stuart Davis, Georgia O’Keeffe, and Arthur Dove is featured, along with photographs by Alfred Stieglitz, Edward Steichen, Charles Sheeler, and Edward Weston. In the central gallery, which is flooded with natural light, visitors can view sculpture and jewelry by Alexander Calder and sculpture by David Smith alongside key works of abstraction by Jackson Pollock, Franz Kline, Adolph Gottlieb, Matta (Roberto Sebastian Matta Echaurren), Norman Lewis, and César Paternosto. These contrast with a gallery of realist works by such artists as Edward Hopper, Andrew Wyeth, George Bellows, and Claudio Bravo. The Jazz Age of the 1920s and ‘30s is evoked in a gallery featuring works designed by Donald Deskey, Viktor Schreckengost, and Paul Frankl, and paintings like Joseph Stella’s dramatic Brooklyn Bridge. Biomorphic and geometric abstraction produced in North and South America in a range of media during the 1940s and ‘50s are also explored on this level, in a display of innovative objects by Charles and Ray Eames, Eero Saarinen, Russel Wright, and other industrial designers and painters.
