Carl Berg (airship Builder)
Carl Berg (4 February 1851, Lüdenscheid – 26 May 1906, Bonn) was a German entrepreneur and airship builder. Berg came from a commercial iron-works family. His great grandfather founded a button-making factory on 1786 in Lüdenscheid. In the following generations the factory developed into an important metal-working company. Among others it incorporated a brass works and an iron works in Eveking (today Werdohl). After his father's death Carl Berg, at the age of 20, took over the firm and expanded it further. Early on he recognised the opportunities in the electrical industries and delivered special wire for the Post to use for telegraph and telephone. Other non-ferrous metals were developed. Berg founded as subsidiaries the copperworks "Deutschland" in Berlin and "Österreich" in Außig (part of Cavertitz, in Bohemia). Above all he realised the advantages of aluminium as a light building material and his Lüdenscheid firm became a pioneer of the aluminium industry. In 18 ...

Zeppelin LZ1
The Zeppelin ''LZ 1'' was the first successful experimental rigid airship. It was first flown from a floating hangar on Lake Constance, near Friedrichshafen in southern Germany, on 2 July 1900.Lueger, Otto: Lexikon der gesamten Technik und ihrer Hilfswissenschaften, Bd. 1 Stuttgart, Leipzig 1920., S. 404–412Luftschiff/ref> "LZ" stood for ''Luftschiff Zeppelin'', or "Airship Zeppelin". Design and development 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. Th ...

People From Lüdenscheid
A person (plural, : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal obligation, legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its us ...

Alfred Wilm
Alfred Wilm (25 June 1869 – 6 August 1937) was a German metallurgist who invented the alloy Al-3.5–5.5%Cu-Mg-Mn, now known as Duralumin which is used extensively in aircraft. Whilst working in military research NUTZ in Neubabelsberg in 1901, Wilm discovered age hardening, in particular age hardening of aluminium alloys. This discovery was made after hardness measurements on Al- Cu alloy specimens were serendipitously found to increase in hardness at room temperature. This increase in hardness was identified after his measurements were interrupted by a weekend, and when they were resumed on the Monday the hardness had increased. By 1906, Wilm had developed an alloy – Al-3.5–5.5%Cu-Mg-Mn, Mg and Mn were < 1%, for which a patent was filed. Later this patent was purchased and the alloy marketed as

Duralumin
Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age-hardenable aluminium alloys. The term is a combination of '' Dürener'' and ''aluminium''. Its use as a trade name is obsolete. Today the term mainly refers to aluminium–copper alloys, designated as the 2000 series by the international alloy designation system (IADS), as with 2014 and 2024 alloys used in airframe fabrication. History Duralumin was developed by the German metallurgist Alfred Wilm at Dürener Metallwerke AG. In 1903, Wilm discovered that after quenching, an aluminium alloy containing 4% copper would harden when left at room temperature for several days. Further improvements led to the introduction of duralumin in 1909. The name is mainly used in pop-science to describe all Al-Cu alloys system, or '2000' series, as designated through the international alloy designation system originally created in 1970 by the Aluminum A ...

List Of Zeppelins
This is a complete list of Zeppelins constructed by the German Zeppelin companies from 1900 until 1938. Other rigid airships that are also sometimes referred to as zeppelins but not built by Zeppelin are not included. The Zeppelin company based in Friedrichshafen, Germany, numbered their aircraft ''LZ 1/2/ ...'', with ''LZ'' standing for "Luftschiff [airship] Zeppelin". Additionally, craft used for civilian purposes were named, whereas military airships were usually given "tactical numbers": * The German Army (German Empire), ''Deutsches Heer'' called its first Zeppelins ''Z I/II/ ... /XI/XII''. During World War I they switched to using ''LZ'' numbers, later adding 30 to obscure the total production. * The Imperial German Navy, ''Kaiserliche Marine'''s Zeppelins were labelled ''L 1/2/ ...''. Since 1997, airships of the new type Zeppelin NT have been flying. They are not included here, as they are Semi-rigid airship, not rigid airships and do not represent a cont ...

Zeppelin LZ 2
The '' LZ 2'' was a German experimental airship constructed by Luftschiffbau Zeppelin and first flown in 1906. It was the true ancestor of later Zeppelin airship designs. The major mistakes made by Kübler in the design of the ''LZ 1'' were not repeated: the designer, Ludwig Dürr, who was to head the design of all subsequent Zeppelins, used triangular-section girders instead of Kübler's flat girders, and elevator An elevator or lift is a wire rope, cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or deck (building), decks of a building, watercraft, ...s instead of a lead weight to control pitch. The life of the ''LZ 2'' was brief, consisting of only two flights. Its near-sister ship, the ''LZ 3''—which first flew on 9 October 1906—was purchased by the German Army and operated as the ''Z I'' until 1913. Before being purchased by the Army, ''LZ 3'' ...

Ferdinand Von Zeppelin
Count Ferdinand von Zeppelin (german: Ferdinand Adolf Heinrich August Graf von Zeppelin; 8 July 1838 – 8 March 1917) was a German general and later inventor of the Zeppelin rigid airships. His name soon became synonymous with airships and dominated long-distance flight until the 1930s. He founded the company Luftschiffbau Zeppelin. Family and personal life Ferdinand was the scion of a noble family. Zepelin, the family's eponymous hometown, is a small community outside the town of Bützow in Mecklenburg. 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 Konstanz, where he was educated by private tutors. Ferdinand married Isabella Freiin von Wolff in Berlin. She was from the house of Alt-Schwanenburg (located in the present-day to ...
