Wikipedia: "Friedrichshafen is a university city on the northern side of Lake Constance (the Bodensee) in Southern Germany, near the borders with Switzerland and Austria. It is the district capital (Kreisstadt) of the Bodensee district (Landeskreis) in the federal state (Bundesland) of Baden-Württemberg. Friedrichshafen has a population of c. 58,000.

Ferdinand von Zeppelin established his famous dirigible factory at the end of the 19th century. The 128m-long LZ1 rose from its mooring on July 2, 1900. Other aviation companies, including Maybach, also arose in Friedrichshafen to help service the industry, which received a major impetus from the First World War. Following the Treaty of Versailles, the Kingdom of Württemberg was dissolved but the deposed royal family continued in their possession of their castle in Friedrichshafen, despite a workers' revolution there in November, 1918."
