Ferdinand von Zeppelin

Ferdinand Adolf Heinrich August Graf von Zeppelin (also known as Ferdinand Graf von Zeppelin, Graf Zeppelin and in English, Count Zeppelin) (8 July 1838 – 8 March 1917) was a German general and later aircraft manufacturer. He founded the Zeppelin Airship company. He was born in Konstanz, Grand Duchy of Baden (now part of Baden-Württemberg, Germany).

Family and personal life
Ferdinand was the scion of a noble family dating back to the year 1400 in Mecklenburg - Pomerania. Zepelin, the eponymous hometown of the family (spelled in German with one "p") is a small community outside the town of Bützow.

Ferdinand was the son of Württemberg Minister and Hofmarschall Friedrich Jerôme Wilhelm Karl Graf von Zeppelin (1807–1886) and his wife Amélie Françoise Pauline (born Macaire d'Hogguer) (1816–1852). Ferdinand spent his childhood with his sister and brother at their Girsberg manor near Constance, where he was educated by private tutors and lived there until his death. On 7 August 1869 Ferdinand married Isabella Freiin von Wolff from the house of Alt-Schwanenburg (present day — Gulbene town in Latvia, then part of Livonia). They had a daughter, Helene (Hella) von Zeppelin (1879–1967) who in 1909 married Alexander Graf von Brandenstein-Zeppelin (1881–1949).

Ferdinand had a nephew Baron Max von Gemmingen who was to later volunteer at the start of World War I, after he was past military age, to become general staff officer assigned to the military airship LZ 12 Sachsen.

Army career
In 1853 Count Zeppelin left to attend the polytechnic at Stuttgart, and in 1855 he became a cadet of the military school at Ludwigsburg and then started his career as an army officer in the army of Württemberg.

By 1858 Zeppelin had been promoted to Lieutenant, and that year he was given leave to study science, engineering and chemistry at Tübingen. The Prussians mobilising for the Austro-Sardinian War interrupted this study in 1859 when he was called up to the Ingenieurkorps (Prussian engineering corps) at Ulm.

In 1863 Zeppelin took leave to act as an observer for the northern troops of the Union's Army of the Potomac in the American Civil War against the Confederates, and later took part in an expedition with Russians and Indians to the source of the Mississippi river and he made his first ascent with Steiner's captive balloon.

In 1865 Zeppelin was appointed adjutant of the King of Württemberg and as general staff officer participated in the Austro-Prussian War of 1866. He was awarded the Ritterkreuz (Knight's Cross) of the Order of Distinguished Service of Württemberg. In the Franco-Prussian War of 1870/1871 a reconnaissance mission behind enemy lines, during which he narrowly avoided capture, made him famous among Germans.

From 1882 until 1885 Zeppelin was commander of the 19th Uhlans in Ulm, and was then appointed to be the envoy of Württemberg in Berlin. In 1890 he gave up this post to return to army service, being given command of a Prussian cavalry brigade. His handling of this at the 1890 autumn manouevres was severely criticised and he was forced to retire from the Army, albeit with the rank of Generalleutnant.

Airships
Ferdinand von Zeppelin served as an official observer with the Union Army during the American Civil War. During the Peninsular Campaign, he visited the balloon camp of Thaddeus S. C. Lowe. Lowe sent the curious von Zeppelin to another balloon camp where the German-born aeronaut John Steiner could be of more help to the young man. His first ascent in a balloon, made at Saint Paul, Minnesota during this visit, is said to have been the inspiration of his later interest in aeronautics.

Zeppelin's ideas for large dirigibles was first expressed in a diary entry dated 25 March 1874. Inspired by a recent lecture given by Heinrich von Stephan on the subject of "World Postal Services and Air Travel", he outlined the basic principle of his later craft: a large rigidly-framed outer envelope containing a number of separate gasbags. In 1887 the success of Charles Renard and Arthur Krebs' airship La France prompted him to send a letter to the King of Württemberg about the military necessity for dirigibles and the lack of German development in this field.

After his resignation from the army in 1891 at age 52, Zeppelin devoted his full attention to airships. He hired the engineer Theodor Gross to make tests of possible materials and to assess available engines for both fuel efficiency and power-to-weight ratio. He also had air propellers tested and strove to obtain higher purity hydrogen gas from suppliers. Zeppelin was so confident of his concept that in June 1891 he wrote to the King of Württemberg's secretary, announcing he was to start building, and shortly after requested a review from the Prussian Army's Chief of General Staff. The next day Zeppelin almost gave up as he realised he had underestimated air resistance, but resumed work on hearing that Rudolf Hans Bartsch von Sigsfeld made light but powerful engines, information soon shown to be overoptimistic. Whereupon Zeppelin urged his supporter Max von Duttenhofer to press Daimler-Motoren-Gesellschaft for more efficient engines so as not to fall behind the French. Duttenhofer wrote to Gross threatening to withdraw support, and Zeppelin shortly afterwards sacked Gross, citing Gross' lack of support and writing that he was "an obstacle in my path".

Despite these setbacks Zeppelin's organization had refined his idea: a rigid aluminium framework covered in a fabric envelope; separate multiple internal gas cells, each free to expand and contract thus obviating the need for ballonets; modular frame allowing addition of sections and gas cells; controls, engines and gondola rigidly attached. After publishing the idea in March 1892 he hired the engineer Theodor Kober who started work testing and further refining the design. Zeppelin submitted Kober's 1893 detailed designs to the Prussian Airship Service, whose committee reviewed it in 1894. In June 1895 this committee recommended minimum funds be granted, but withdrew this offer and rejected the design in July.

One month later, in August 1895, Zeppelin received a patent for Kober's design, described as an "airship-train" (Lenkbarer Luftfahrzug mit mehreren hintereinanderen angeordneten Tragkörpern [Steerable airship-train with several carrier structures arranged one behind another].) The patent describes an airship consisting of three rigid sections flexibly connected. The front section, intended to contain the crew and engines, was 117.35 m (385 ft) long with a gas capacity of 9514 cu m (336,000 cu ft): the middle section was 16 m (52 ft 6 in) long with an intended useful load of 599 kg (1320 lb) and the rear section 39.93 m (131 ft) long with an intended load of 1996 kg (4,400 lb)

In early 1896 Zeppelin's lecture on steerable airship designs given to the Association of German Engineers (VDI) so impressed them that the VDI launched a public appeal for financial support for him. This led to a first contact with Carl Berg who supplied aluminium alloys which Zeppelin had tested, and by May 1898 they, together with Philipp Holzmann, Daimler, Max von Eyth, Carl von Linde, and Friedrich Voith, had formed the joint stock company Gesellschaft zur Förderung der Luftschiffart. Zeppelin invested 441,000 Marks, over half the total capital. Actual construction then started of what was to be the first successful rigid airship, the Zeppelin LZ1.

Berg's involvement with the project would later be the cause of allegations that Zeppelin had used the patent and designs of David Schwarz's airship of 1897. Berg had signed a contract with Schwartz under the terms of which he undertook not to supply aluminium to any other airship manufacturer. He later made a payment to Schwartz's widow as compensation for dissolving this arrangement. Claims that Zeppelin had been influenced by Schwartz were denied by Eckener in 1938 and also rejected by later historians. Zeppelin's design was "radically different" in both its scale and its framework from that of Schwarz.

On 2 July 1900, Zeppelin made the first flight with the LZ 1 over Lake Constance near Friedrichshafen in southern Germany. The airship rose from the ground and remained in the air for 20 minutes, but was damaged on landing. After repairs and some modifications two further flights were made by LZ 1 in October 1900, However the airship was not considered successful enough to justify investment by the government, and since the experiments had exhausted Count Zeppelins funds, he was forced to suspend his work.

Zeppelin still enjoyed the support of the King of Württemberg, who authorised a state lottery which raised 124,000 marks. A contribution of 50,000 marks was received from Prussia, and Zeppelin raised the remainder of the necessary money by mortgaging his wife's estates. Still supported by Daimler and Carl Berg, construction of his second airship, the LZ 2, was started in April 1905. It was completed by 30 November, when it was first taken out of its hangar, but a ground-handling mishap caused the bows to be pulled into the water, damaging the forward control surfaces. Repairs were completed by 17 January 1906, when LZ 2 made its only flight. Too much ballast was jettisoned on takeoff, causing the airship to rise to an altitude of 427 m (1,500 ft). Here a stiff breeze was encountered, and although the airship was at first able to overcome this, the failure of the forward engine due to cooling problems followed by the failure of the other due to a broken clutch-spring left the airship at the mercy of the wind. It was brought down near Kisslegg in the Allgäu mountains, with some damage caused by the stern striking some trees during mooring, but was more severely damaged by high winds the following night, and had to be dismantled. In May 1906 work as started on a third airship, LZ 3. This was the same size and configuration as LZ 2, but had a greater gas capacity. Finished by the end of the year, it made two successful flights at a speed of 30 mph, and in 1907 attained a speed of 36 mph. The success of LZ 3 produced a change in the official attitude to his work, and the Reichstag voted that he should be awarded 500,000 marks to continue his work. However the purchase by the Government of an airship was made conditional on the successful completion of a 24 hour trial flight. Knowing that this was beyond the capabilities of LZ 3, work was started on a larger airship, the LZ 4. This first flew on 20 June 1908. The final financial breakthrough only came after the Zeppelin LZ 4 was destroyed by fire at Echterdingen after breaking free of its moorings during a storm. The airship's earlier flights had excited public interest in the development of the airships, and a subsequent collection campaign raised over 6 million German marks. The money was used to create the 'Luftschiffbau-Zeppelin GmbH' and the Zeppelin foundation (Zeppelin Stiftung).

Following the destruction of LZ 4, LZ 3, which had been damaged when the floating hangar broke free of its mooring during a storm, was repaired: at the same time it was lengthened by 8 m. It was re-inflated on 21 October 1908 and after a series of short test flights a flight lasting 5 hours 55 minutes took place on 27 October with the Kaiser's brother, Admiral Prince Heinrich, on board. On 7 November, with Crown Prince William as a passenger, it flew 80 km (50 mi) to Donaueschingen, where the Kaiser was then staying. In spite of poor weather conditions, the flight succeeded: two days later LZ 3 was officially accepted by the Government and on 10 November Zeppelin was rewarded with an official visit to Friedrichshafen by the Kaiser, during which a short demonstration flight over Lake Constance was made and Zeppelin awarded the Order of the Black Eagle.

Although a replacement for LZ 4, the LZ 5 was built and accepted into Army service as L II, Zeppelin's relationship with the military authorities continued to be poor, and deteriorated considerably due to his criticism of the Army following the loss of L II, which was carried away from its moorings and wrecked on 25 April 1910. However, the business director of Luftschiffbau-Zeppelin, Alfred Colsman, came up with a scheme to capitalise on the public enthusiasm for Zeppelin's airships by establishing a passenger-carrying business. Up until 1914 the German Aviation Association (Deutsche Luftschiffahrtsgesellschaft or DELAG) transported 37,250 people on over 1,600 flights without an incident. Within a few years the zeppelin revolution began creating the age of air transportation.

Family
Count Everhard von Zeppelin, Second Lieutenant in the German Lancers, married November, 1895, Mamie McGarvey, daughter of William H. McGarvey, owner of the oil wells of Galicia and his wife, Helena J. Wesolowska. A former Count von Zeppelin married a granddaughter of the 1st Earl of Ranfurly.

Legacy
Count Zeppelin died in 1917, before the end of World War I. He therefore did not witness either the provisional shutdown of the Zeppelin project due to the Treaty of Versailles or the second resurgence of the zeppelins under his successor Hugo Eckener.

The unfinished World War II German aircraft carrier Graf Zeppelin, and two rigid airships, the world-circling LZ 127 Graf Zeppelin, and LZ 130 Graf Zeppelin II, twin to the Hindenburg, were named after him.

The British rock group Led Zeppelin's name derives from his airship as well. His granddaughter, Countess Eva von Zeppelin, even once threatened to sue Led Zeppelin for illegal use of their family name while performing in Copenhagen.
