This week, Hoover Library & Archives acquired the collection of Stuart Canin—a World War II veteran, former concert master of the San Francisco Symphony, and the subject of the forthcoming documentary The Rifleman’s Violin, which tells the dramatic story of Canin’s musical performance, given at the age of nineteen, for Harry Truman, Joseph Stalin, and Winston Churchill during the July 1945 Potsdam Conference. The materials, now available in the Hoover Library & Archives reading room, include the young GI’s letters written to his parents during the Potsdam Conference, and photographs taken in Berlin and other European cities during Canin’s years of service.
