Lewis Hine believed that if these new American citizens left their jobs, went back to Europe, and served in the war, their families would be left without any means of financial support. By this time, the focus of Hine’s photographic work had shifted. At first, he had continued to take photographs for the National Child Labor Committee. But as World War the author dragged on, Americans began to lose interest in reform as their attention shifted to the conflict in Europe. Many of Hine’s pictures, not surprisingly, were of French children. He showed a grim-faced boy fishing on the banks of the Seine River in Paris, a lovely little girl wearing a white dress in Normandy, and a delivery boy, with a big smile on his face, pulling a cart in Chateauveaux. One of Hine’s pictures showed a new house constructed by the government amid the rubble of bombed-out buildings to serve as a home for refugees.
