The story
Founded by Friedrich Krupp in 1903.1
Franco-Prussian War
The unexpected victory of Prussia over France (19 July 1870 – 10 May 1871) demonstrated the superiority of breech-loaded steel cannon over muzzle-loaded brass. Krupp artillery was a significant factor at the battles of Wissembourg and Gravelotte, and was used during the siege of Paris. Krupp's anti-balloon guns were the first anti-aircraft guns. Prussia fortified the major North German ports with batteries that could hit French ships from a distance of 4,000 yd (3.7 km; 2.3 mi), inhibiting invasion.
Venezuela Crisis
Krupp's construction of the Great Venezuela Railway from 1888 to 1894 raised Venezuelan national debt. Venezuela's suspension of debt payments in 1901 led to gunboat diplomacy of the Venezuela Crisis of 1902–1903.
Balkan Wars
Russia and the Ottoman Empire both bought large quantities of Krupp guns. By 1887, Russia had bought 3,096 Krupp guns, while the Ottomans bought 2,773 Krupp guns. By the start of the Balkan Wars the largest export market for Krupp worldwide was Turkey, which purchased 3,943 Krupp guns of various types between 1854 and 1912. The second-largest customer in the Balkans was Romania, which purchased 1,450 guns in the same period, while Bulgaria purchased 517 pieces, Greece 356, Austria-Hungary 298, Montenegro 25, and Serbia just 6 guns.
World War I
Krupp produced most of the artillery of the Imperial German Army, including its heavy siege guns: the 1914 420 mm Big Bertha, the 1916 Langer Max, and the seven Paris Guns in 1917 and 1918. In addition, Friedrich Krupp Germaniawerft built German warships and submarines in Kiel. During the war, Krupp also modified the design of an existing Langer Max gun, which they built in Koekelare. The gun called Batterie Pommern was the largest gun in the world in 1917 and was able to shoot shells of ±750 kg from Koekelare to Dunkirk.
Before World War I Krupp had a contract with the British armaments company Vickers and Son Ltd. (formerly Vickers Maxim) to supply Vickers-constructed Maxim machine guns. Conversely, from 1902 Krupp was contracted by Vickers to supply its patented fuses to Vickers bullets. It is known that wounded and deceased German soldiers were found to have spent Vickers bullets with the German inscription "Krupps patent zünder [fuses]" lying around their bodies.
World War II
Krupp received its first order for 135 Panzer I tanks in 1933, and during World War II made tanks, artillery, naval guns, armor plate, munitions and other armaments for the German military. Friedrich Krupp Germaniawerft shipyard launched the cruiser Prinz Eugen, as well as many of Germany's U-boats (130 between 1934 and 1945) using preassembled parts supplied by other Krupp factories in a process similar to the construction of the US liberty ships.
In the 1930s, Krupp developed two 800 mm railway guns, the Schwerer Gustav and the Dora. These guns were the biggest artillery pieces ever fielded by an army during wartime, and weighed almost 1,344 tons. They could fire a 7-ton shell over a distance of 37 kilometers. More crucial to the operations of the German military was Krupp's development of the famed 88 mm anti-aircraft cannon which found use as a notoriously effective anti-tank gun.
In an address to the Hitler Youth, Adolf Hitler stated "In our eyes, the German boy of the future must be slim and slender, as fast as a greyhound, tough as leather and hard as Krupp steel" ("... der deutsche Junge der Zukunft muß schlank und rank sein, flink wie Windhunde, zäh wie Leder und hart wie Kruppstahl.")

During the war Germany's industry was heavily bombed. The Germans built large-scale night-time decoys like the Krupp decoy site (German: Kruppsche Nachtscheinanlage) which was a German decoy-site of the Krupp steel works in Essen. During World War II, it was designed to divert Allied airstrikes from the actual production site of the arms factory.
Krupp Industries employed workers conscripted by the Nazi regime from across Europe. These workers were initially paid, but as Nazi fortunes declined they were kept as slave workers. They were abused, beaten, and starved by the thousands, as detailed in the book The Arms of Krupp. Nazi Germany kept two million French POWs captured in 1940 as forced laborers throughout the war. They added compulsory (and volunteer) workers from occupied nations, especially in metal factories. The shortage of volunteers led the Vichy government of France to deport workers to Germany, where they constituted 15% of the labor force by August 1944. The largest number worked in the giant Krupp steel works in Essen. Low pay, long hours, frequent bombings, and crowded air raid shelters added to the unpleasantness of poor housing, inadequate heating, limited food, and poor medical care, all compounded by harsh Nazi discipline. In an affidavit provided at the Nuremberg Trials following the war, Dr. Wilhelm Jaeger, the senior doctor for the Krupp slaves, wrote:
Sanitary conditions were atrocious. At Kramerplatz only ten children's toilets were available for 1200 inhabitants...Excretion contaminated the entire floors of these lavatories. The Tatars and Kirghiz suffered most; they collapsed like flies [from] bad housing, the poor quality and insufficient quantity of food, overwork and insufficient rest...Countless fleas, bugs and other vermin tortured the inhabitants of these camps..." The survivors finally returned home in the summer of 1945 after their liberation by the allied armies.
Krupp industries was prosecuted after the end of war for its support to the Nazi regime and use of forced labour.
Post–World War II
Krupp's trucks were once again produced after the war, but so as to minimize the negative wartime connotations of the Krupp name they were sold as "Südwerke" trucks from 1946 until 1954, when the Krupp name was considered rehabilitated.
The Mustang
Krupp also used the name "Mustang" for some of their products, causing a problem for Ford Motor Company in 1964 when they desired to export their car of the same name to Germany, especially since American military personnel stationed there wanted the new car. Although Krupp offered to sell the Mustang name to Ford for a reasonable price, Ford declined and as a result, badged all Mustangs destined for Germany "T-5." By 1978 Krupp's rights to the Mustang name expired and all Mustangs exported to Germany henceforth retained the Mustang name.
Other accomplishments
Krupp Steel Works of Essen, Germany, manufactured the spherical pressure chamber of the dive vessel Trieste, the first vessel to take humans to the deepest known point in the oceans, accomplished in 1960. This was a heavy duty replacement for the original pressure sphere (made in Italy by Acciaierie Terni) and was manufactured in three finely machined sections: an equatorial ring and two hemispherical caps. The sphere weighed 13 tonnes in air (net displacement eight tonnes in water) with walls that were 12.7 centimetres (5.0 in) thick.
Krupp Steel Works was also contracted in the mid-1960s to construct the Effelsberg 100-m Radio Telescope, which, from 1972 to 2000 was the largest fully steerable radio telescope in the world.
Railway expansion period
Krupp was the first company to patent a seamless, reliable and strong enough railway tyre for rail freight. Krupp received original contracts in the United States and enjoyed a period of technological superiority while also contributing the majority of rail to the new continental railway system. "Nearly all railroads were using Krupp rails, the New York Central, Illinois Central, Delaware and Hudson, Maine Central, Lake Shore and Michigan Southern, Bangor and Aroostook, Great Northern, Boston and Albany, Florida and East Coast, Texas and Pacific, Southern Pacific, and Mexican National."
Diesel engines
In 1893, a mechanical engineer by the name of Rudolf Diesel approached Gustav with a patent for a "new kind of internal combustion engine employing autoignition of the fuel". He also included his text "Theorie und Konstruktion eines rationellen Wärmemotors". Four years later, the first 3-horsepower diesel engine was produced.
