 In 1923, the first of many expansions of the Art Museum was completed with the addition of the Venetian Gothic McCormick Hall, designed by Ralph Adams Cram and donated by the family of Cyrus McCormick, Jr., Class of 1879 and Harold Fowler McCormick, Class of 1895.The new building enabled the older structure to be devoted solely to the museum, and led to the creation of a hall of casts on the ground floor.As Marquand had before him, Mather augmented the museum's collections through the use of his personal fortune, with contributions ranging from Classical and Pre-Columbian antiquities, to illuminated manuscripts, and what became one of the finest collections of American drawings in the country.
