The Zeppelin LZ 1 was the first truly successful experimental rigid airship. It was first flown from a floating hangar on Lake Constance, near Friedrichshafen in southern Germany on 2 July 1900. "LZ" stood for Luftschiff Zeppelin, or "Airship Zeppelin"
Count Zeppelin had been devoting his energies to the design of large rigid-framed airships since his retirement from the Army in 1890. In 1898 he established the Gesellschaft zur Förderung der Luftschifffahrt. The company had a subscribed capital of 800,000 Deutschmarks, of which Zeppelin contributed 300,000 Deutschmarks: the remainder was provided by various industrialists, including 100,000 Deutschmarks contributed by Carl Berg, whose company provided the aluminium framework of the airship. The company first constructed a large floating shed to contain the airship. This arrangement was decided on firstly because Zeppelin believed that landing the ship over water would be safer and secondly because the floating shed, moored only at one end, would turn so that it was always facing into the wind.
The LZ 1 was constructed using a cylindrical framework with 16 wire-braced polygonal transverse frames and 24 longitudinal members covered with smooth surfaced cotton cloth. Inside was a row of 17 gas cells made from rubberized cotton. The airship was steered by forward and aft rudders and propulsion was provided by two 10.6 kW (14.2 hp) Daimler NL-1 internal-combustion engines, each driving two propellers mounted on the envelope. Pitch control was by use of a 100 kg (220 lb) weight suspended beneath the hull which could be winched forward or aft to control its attitude. Passengers and crew were carried in two 6.2 m (20 ft) long aluminium gondolas suspended forward and aft.
Construction of the airship began on 17 June 1898, when the first sections of the framework were delivered from Berg's factory and was completed by 27 January 1900. Inflation of the gasbags took place during June and the airship was first taken out of the shed on the evening of 2 July, with Hauptmann Hans Bartsch von Sigsfeld of the Prussian Airship Battalion at the controls.
