Document 2: Henry Lehman: In 1855, Henry Lehman died from yellow fever while travelling in New Orleans. Later, his brothers moved the company's headquarters to New York City, eventually building it into an important American investment bank, which was in operation for over 150 years until its September 15, 2008 collapse.
Document 3: Edinburgh: Banking has been a mainstay of the Edinburgh economy for over 300 years, since the Bank of Scotland (now part of the Lloyds Banking Group) was established by an act of the Scottish Parliament in 1695. Today, the financial services industry, with its particularly strong insurance and investment sectors, and underpinned by Edinburgh-based firms such as Scottish Widows and Standard Life Aberdeen, accounts for the city being the UK's second financial centre after London and Europe's fourth in terms of equity assets. The Royal Bank of Scotland opened new global headquarters at Gogarburn in the west of the city in October 2005, and Edinburgh is home to the headquarters of Bank of Scotland, Sainsbury's Bank, Tesco Bank, TSB Bank and Virgin Money.
Document 4: Department store: The design and function of department stores in Germany followed the lead of London, Paris and New York. Germany used to have a number of department stores; nowadays only a few of them remain. Next to some smaller, independent department stores these are Karstadt (in 2010 taken over by Nicolas Berggruen, also operating the KaDeWe in Berlin, the Alsterhaus in Hamburg and the Oberpollinger in Munich), GALERIA Kaufhof (part of the Metro AG). Others like Hertie, Wertheim and Horten AG were taken over by others and either fully integrated or later closed.
Document 5: Mendelssohn & Co.: Mendelssohn & Co. survived the financial meltdown of the 1930s comparatively well. Following the death of Franz von Mendelssohn and in 1935, Rudolf Löb was appointed as chairman of the bank, the first non-family member to be chairman. In 1938, under intense pressure of the Nazis' Aryanization policy, Mendelssohn & Co. were forced to hand over their assets to Deutsche Bank, and eventually to shut down.
Document 6: Leo Arons: Leo Arons came from a wealthy Jewish banking family in Berlin. His parents were Albert Arons (1826-1897), a partner in the prestigious private banking house "Gebrüder Arons", and Clara Goldschmidt (1837-1867). In 1887 Leo Arons married Johanna Bleichröder (1861-1938), a daughter of the banker Julius Bleichröder (1828-1907). Arons' brother, the banker Paul Arons (1861-1932), married Johanna's sister Gertrude (1865-1917) a few years later.
Document 7: Rudolf Löb: Rudolf Löb (November 21, 1877 – January 30, 1966) was a German banker with Mendelssohn & Co. and consultant to the German and Russian governments.
Document 8: Department store: France's major upscale department stores are Galeries Lafayette and Le Printemps, which both have flagship stores on Boulevard Haussmann in Paris and branches around the country. The first department store in France, Le Bon Marché in Paris, was founded in 1852 and is now owned by the luxury goods conglomerate LVMH. La Samaritaine, another upscale department store also owned by LVMH, closed in 2005. Mid-range department stores chains also exist in France such as the BHV (Bazar de l'Hotel de Ville), part of the same group as Galeries Lafayette.
Document 9: Gerson von Bleichröder: Bleichröder was born in Berlin. He was the eldest son of Samuel Bleichröder, who founded the banking firm of S. Bleichröder in 1803 in Berlin. Gerson first joined the family business in 1839. In 1855 upon the death of his father, Gerson became the head of the banking firm. The bank maintained close contacts with the Rothschild family; the banking house of Bleichröder acted as a branch office in Berlin of the Rothschilds' bank.
Document 10: Knorr-Bremse: Engineer Georg Knorr established "Knorr-Bremse GmbH" in 1905 in Boxhagen-Rummelsburg, Neue Bahnhofstraße, near Berlin (since 1920 part of Berlin-Friedrichshain). Its production of railway braking systems derived from a company ("Carpenter & Schulze") founded in 1883. In 1911 the company merged with "Continentale Bremsen-GmbH" to found "Knorr-Bremse Aktiengesellschaft" (AG). From 1913 onwards, a second manufacturing plant, new headquarters, a heating plant and other annex buildings were erected.
Document 11: Department store: Before the 1950s, the department store held an eminent place in both Canada and Australia, during both the Great Depression and World War II. Since then, they have suffered from strong competition from specialist stores. Most recently the competition has intensified with the advent of larger-scale superstores (Jones et al. 1994; Merrilees and Miller 1997). Competition was not the only reason for the department stores' weakening strength; the changing structure of cities also affected them. The compact and centralized 19th century city with its mass transit lines converging on the downtown was a perfect environment for department store growth. But as residents moved out of the downtown areas to the suburbs, the large, downtown department stores became inconvenient and lost business to the newer suburban shopping malls. In 2003, U.S. department store sales were surpassed by big-box store sales for the first time (though some stores may be classified as "big box" by physical layout and "department store" by merchandise).
Document 12: Department store: All major cities have their distinctive local department stores, which anchored the downtown shopping district until the arrival of the malls in the 1960s. Washington, for example, after 1887 had Woodward & Lothrop and Garfinckel's starting in 1905. Garfield's went bankrupt in 1990, as did Woodward & Lothrop in 1994. Baltimore had four major department stores: Hutzler's was the prestige leader, followed by Hecht's, Hochschild's and Stewart's. They all operated branches in the suburbs, but all closed in the late twentieth century. By 2015, most locally owned department stores around the country had been consolidated into larger chains, or had closed down entirely.
Document 13: Rudolf Leopold: Rudolf Leopold (1 March 1925 – 29 June 2010) was an Austrian art collector, whose collection of 5,000 works of art was purchased by the Government of Austria and used to create the Leopold Museum, of which he was made director for life. Claims had been made by Jewish survivors of the Holocaust that some of the pieces in the collection were Nazi plunder and should be returned to their rightful owners.
Document 14: Mendelssohn & Co.: It was established in 1795 by Joseph Mendelssohn in Berlin. In 1804, his younger brother Abraham Mendelssohn Bartholdy joined the company. In 1815, they moved into their new headquarters at Jägerstraße 51, thereby laying the foundations of Berlin's financial district. Mendelssohn & Co. remained in that building until its divestiture in 1939.
Document 15: Johann von Berenberg-Gossler: Baron Johann von Berenberg-Gossler (born 13 February 1839 in Hamburg, died 8 December 1913 in Hamburg; né Johann Gossler), known as "John," was a German banker from the city-state of Hamburg and owner and head of Berenberg Bank from 1879 until his death.
