As secretary for the Beijing YMCA, Sidney Gamble made three trips to China between 1917 and 1932. During these visits, this Princeton-educated sociologist photographed such pivotal events as the Thanksgiving celebrations following the end of World War I and Sun Yat-sen's funeral. Duke University's thought-provoking exhibit presents dozens of Gamble's photographs, along with erudite essays contextualizing and problematizing Gamble's photographic journey into China's "class, commerce, gender, and transition to modernity." Special treats include Jason Tonio Woerner's essay on "Penetrating the Past" and Gamble's photographs of street scenes.
