Advisor to U.S. State Department on Restitution of Cultural Materials
After graduating from Andover, Crosby studied art history at Yale and then in France. He returned to teach at Yale. According to the National Archives, from 1944–45 Crosby was appointed special adviser to the American Commission for the Protection and Salvage of Artistic and Historic Monuments in Europe, which had been set up the year before to monitor cultural artifacts in war zones. The Commission was responsible not only for identifying and protecting monuments at risk but also for overseeing restitution for any looted or destroyed artworks to their governments of origin. Today there is an art gallery named after Crosby at Yale.
