From 1811 to 1969, the academy organized important annual art exhibitions, from which the museum made significant acquisitions. Harrison S. Morris, Managing Director from 1892 to 1905, collected contemporary American art for the institution. Among the many masterpieces acquired during his tenure were works by Cecilia Beaux, William Merritt Chase, Frank Duveneck, Thomas Eakins, Winslow Homer, Childe Hassam, and Edmund Tarbell.
