LZ 127 Graf Zeppelin was a German passenger-carrying hydrogen-filled rigid airship that flew from 1928 to 1937. It offered the first commercial transatlantic passenger flight service. The ship was named after the German airship pioneer Ferdinand von Zeppelin, a count in the German nobility. It was conceived and operated by Hugo Eckener, the chairman of Luftschiffbau Zeppelin.
