Dornier, Claude (1884–1969)
Claude Dornier was a German aircraft manufacturer who designed and manufactured the first all-metal airplane. While working with Ferdinand von Zeppelin, the airship manufacturer, Dornier founded an aircraft company and built wooden and metal planes which served World War I (1914–18). In 1929, he designed the DO-X, a 12-engined passenger plane. From the late 1940s, Dornier's company built US-designed aircraft.
