The Zeppelin Company, founded in 1908 by Ferdinand von Zeppelin, was a pioneer company renowned for its airships and transoceanic commercial air service. Ferdinand von Zeppelin had been experimenting with rigid airships since the late 1800s and the Zeppelin LZ 1 made its first flight in 1900. Further models followed until the LZ 4 was introduced in 1908. The LZ 4 crashed during a test flight which lead to an outpouring of support and monetary donations from the public which made possible the founding of the Zeppelin Company (Luftschiffbau Zeppelin GmbH). Beginning in 1909, Zeppelin airships were used for passenger transport by the Deutsche Luftschiffahrts Aktiengesellschaft (DELAG).
