Footnote: Ludwig Dürr (June 4, 1878 in Stuttgart - January 1, 1956 in Friedrichshafen) was an airship designer. After completing training as a mechanic, Dürr continued his training at the Königliche Baugewerkschule (Royal School of Engineering). In 1898, he entered the German Navy, but was discharged at the end of the year. Beginning in 1899, Dürr worked for Ferdinand von Zeppelin. After assisting in the construction of the first zeppelin airship, the LZ 1, he himself began to construct airships and lightweight construction parts. All of the following zeppelin designs were Dürr's. He often flew on board his designs, at the elevator control wheel, including the maiden flight of Zeppelin LZ 5 to Bitterfeld and back. On May 31, 1909, Dürr was still, exhausted, at the elevator controls after the 37 hour flight, when the nose of the ship crashed into a pear tree near Göppingen. He was employed by the Zeppelin company until its dissolution in 1945, from 1915 on as technical director.
