While Ray and Charles Eames specialized in designing objects for everyday use, like the chair on view in this gallery, they also invented numerous medical and aeronautical devices for the United States military, using their craftsmanship and creativity to support the war. This leg splint is manufactured from lightweight plywood with a soft surface of veneer, or thin sheets of wood. As battle injuries increased during World War II (1939–1945), the United States Navy sought to correct the weight and discomfort of metal splints. This design’s curving surface reduces friction, and slits for fabric ties enabled more flexibility while stabilizing and transporting wounded soldiers. The designers used Charles’ own leg as a model.
