LZ 129 Hindenburg was a German commercial passenger-carrying rigid airship, the lead ship of its class, the longest class of flying machine and the largest airship by envelope volume. It was designed and built by the Zeppelin Company on the shores of Lake Constance in Friedrichshafen, Germany, and was operated by the German Zeppelin Airline Company. It was named after Field Marshal Paul von Hindenburg, who was President of Germany from 1925 until his death in 1934.
