Count Ferdinand von Zeppelin (1838-1917), German inventor of the airship. Von Zeppelin conceived the idea of confining the hot air balloon, first developed in 1783, within a cigar-shaped aluminum structure, and providing the airship with an internal combustion engine and a propeller. The first flight of the von Zeppelin dirigible took place on 2 July 1900. The cotton-covered balloon was 128 meters long. Between 1900 and 1939, 52,000 people traveled a total of 2 million kilometers in such airships. The accident of the Hindenburg dirigible, which burst into flames in 1937, brought the fashion for airships to an end.
