Karl Arnstein's life was defined by the world wars which shattered Europe. But for these cataclysmic events, his life's work might have been far different. From Zeppelin in Germany to Goodyear in Akron, Ohio, Arnstein participated in the design and development of more airships than any other engineer. His story is in many ways the story of airship building in the early decades of the twentieth century. And his legacy endures in the Goodyear blimps which are the tire company's corporate icons and the symbols of Akron's important airship heritage.
