It’s 1918 and France was caught in the final year of World War I.

American photographer Lewis Hine traveled across the country for the American Red Cross, documenting their work with refugees, orphans, and wounded soldiers. Lost for decades, his poignant work has recently been made public by the Library of Congress.

Lewis Hine has been acknowledged as one of America’s principal 20th-century photographers, best known for his moving portraits of immigrants on Ellis Island, child laborers in factories and mines, and steelworkers balanced on high girders of the Empire State Building.

In World War I, Hine became a photographer for the Red Cross, assigned to record the devastation in Europe and document the need for relief work.

In the spring and summer of 1918, he photographed hundreds of war refugees, orphaned children, hospitalized U.S. soldiers, nurses, and volunteers, as well as the country’s ruins.

Original caption: “Jeanne Septvents is a beautiful French girl, 10 years old, whose father, for nearly a year a prisoner in Germany, has given his life for France. Jeanne has been adopted by Company ‘E,’ 6th Battalion of the 20th Engineers. When the American Red Cross photographer found her in the garden of her little stone house at Caen, she was playing with knuckle-bones that she had painted red, white, and blue in honor of her godfathers. She wrote them soon after she was adopted saying: ‘I hope you are all in good health and not too unhappy at the front and I send big kisses to you all.’ September, 1918.”

The photographs were intended to drum up support for the Red Cross and appeal to an American audience.

Some of these pictures appeared in Red Cross publications, but most of them went into the organization’s archives, where they remained hidden for almost 100 years.

At the end of World War II, the Red Cross deposited its photograph collection — some 50,000 images — at the Library of Congress, where Hine’s work was ”lost” due to an eccentric filing code that baffled historians for nearly 40 years.

Author Daile Kaplan was finally able to break the code, identify Hine’s photographs, and reintroduce to the world the best of this master’s “lost” photographs, giving him his due, at last, as a true pioneer of photojournalism.

The boy has been adopted by the 101st Machine Gun Battalion. Thanks to the money which they have sent him, he will go to a trade school and then he will be able to support his little brother Pierre. For the war will surely be over before Roger’s class is called, and then he and Pierre can go back to Lorraine, which is their home even if their house is destroyed and even if the father and mother are both gone. August, 1918.”

Original caption: “Two months ago, little Gilberte Dieu and her mother left their home in the Somme to go see the soldier father who was in a hospital, badly gassed. When they reached the town where he was, they learned that the Germans were approaching their home, and if they wished to save any of their possessions they must hurry back. They started home, only to find they were too late. Again they turned around to go back to the hospital, hoping to find the father better, and learned that he was dead. Now they are living in a quiet old town in Normandy. Gilberte is as pale as if she had been ill a long time, but she has been adopted by Company E of the 406th Telegraph Battalion, and the money they have sent will provide her generously with good food and warm clothing for next winter. Perhaps with these, the memory of what the war has done to her will fade out partly from her tragic little face. September, 1918.”

Their earnings average five to six francs a day. September, 1918.”
