Bertha Krupp von Bohlen und Halbach (29 March 1886 – 21 September 1957) was a member of the Krupp family, Germany's leading industrial dynasty of the 19th and 20th centuries.
 As the elder child and heir of Friedrich Alfred Krupp she was the sole proprietor of the Krupp industrial empire from 1902 to 1943, although her husband, Gustav Krupp von Bohlen und Halbach, ran the company in her name.
 In 1943 ownership of the company was transferred to her son Alfried.

The Arms of Krupp (1968) is William Manchester's history of the Krupp dynasty, which owned and ran a dominant armaments manufacturing company in Germany.
 The company was based in Essen.
 The book presents very readable descriptions of the behavior of the Krupp family and its firm from the Thirty Years' War to the Kaisers, the Weimar Republic, the Nazis, the American occupation, and finally the Bonn government.
 The book describes how under each regime (except possibly Weimar) the family and firm received favorable treatment, culminating in a special law Lex Krupp.
 Bizarre facets of families members are presented in detail.
 The innovative social welfare programs for factory workers are starkly contrasted with the treatment of forced laborers (ostarbeiters, etc.) Manchester's book tells presumably all-from the first Krupp (circa 1500) "a shrewd chandler with a keen eye for the main chance," through the family's incarnation by the sixth generation as "Essen's uncrowned kings," to the powerful weapons empire that armed Germany for three major wars, and finally the dissolution of die Firma.
 Manchester slants his story; in this case, the Krupps are all malevolent.
 The "killing power" of the kruppsche wares (cannon, howitzers, batteries, finally, nuclear power) was unrivaled as early as 1880, and in Manchester's view their product suited the family's temperament.
 He does differentiate between the various Alfreds, Alfrieds, and Berthas—but shows every member with some unfortunate trait.
 Their way of life is "secretive," their huge empire "international," their tendency is toward cartels, and their appearance is "vulpine."
 The foxy family's most "phenomenal" habit, however, was that "of matching the Teuton mood"—i.e. they were nationalistic, Francophile, or severely militaristic when Germany adopted these stances.
 But Manchester doesn't quite make it clear whether he is charging them with fierce patriotism or whoring.
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, have become famous for their production of steel, artillery, ammunition, and other armaments.
 The family business, known as Friedrich Krupp AG, was the largest company in Europe at the beginning of the 20th century.
 It was important to weapons development and production in both world wars.
 One of the most powerful dynasties in European history, for 400 years Krupp flourished as the premier weapons manufacturer for Germany.
 From the Thirty Years' War until the end of the Second World War, they produced everything from battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities.
