Some context: Marguerite "Peggy" Guggenheim (August 26, 1898 - December 23, 1979) was an American art collector, bohemian and socialite. Born to the wealthy New York City Guggenheim family, she was the daughter of Benjamin Guggenheim, who went down with the Titanic in 1912, and the niece of Solomon R. Guggenheim, who would establish the Solomon R. Guggenheim Foundation. Peggy Guggenheim created a noted art collection in Europe and America primarily between 1938 and 1946. She exhibited this collection as she built it and in 1949, settled in Venice, where she lived and exhibited her collection for the rest of her life.
When Peggy Guggenheim realized that her gallery, although well received, had made a loss of PS600 in the first year, she decided to spend her money in a more practical way. A museum for contemporary arts was exactly the institution she could see herself supporting. Most certainly on her mind also were the adventures in New York City of her uncle, Solomon R. Guggenheim, who, with the help and encouragement of Hilla Rebay, had created the Solomon R. Guggenheim Foundation two years earlier. The main aim of this foundation had been to collect and to further the production of abstract art, resulting in the opening of the Museum of Non-objective Painting (from 1952: The Solomon R. Guggenheim Museum) earlier in 1939 on East 54th Street in Manhattan. Peggy Guggenheim closed Guggenheim Jeune with a farewell party on 22 June 1939, at which colour portrait photographs by Gisele Freund were projected on the walls. She started making plans for a Museum of Modern Art in London together with the English art historian and art critic Herbert Read. She set aside $40,000 for the museum's running costs. However, these funds were soon overstretched with the organisers' ambitions.  In August 1939, Peggy Guggenheim left for Paris to negotiate loans of artworks for the first exhibition. In her luggage was a list drawn up by Herbert Read for this occasion. Shortly after her departure the Second World War broke out, and the events following 1 September 1939 made her abandon the scheme, willingly or not. She then "decided now to buy paintings by all the painters who were on Herbert Read's list. Having plenty of time and all the museum's funds at my disposal, I put myself on a regime to buy one picture a day." When finished, she had acquired ten Picassos, forty Ernsts, eight Miros, four Magrittes, three Man Rays, three Dalis, one Klee, one Wolfgang Paalen and one Chagall among others. In the meantime, she had also made new plans and in April 1940 had rented a large space in the Place Vendome as a new home for her museum.  A few days before the Germans reached Paris, Peggy Guggenheim had to abandon her plans for a Paris museum, and fled to the south of France, from where, after months of safeguarding her collection and artist friends, she left Europe for New York in the summer of 1941. There, in the following year, she opened a new gallery which actually was in part a museum at 30 West 57th Street. It was called The Art of This Century Gallery. Three of the four galleries were dedicated to Cubist and Abstract art, Surrealism and Kinetic art, with only the fourth, the front room, being a commercial gallery. Peggy Guggenheim held important shows, such as the show for 31 Women artists, at the gallery as well.  Her interest in new art was instrumental in advancing the careers of several important modern artists including the American painters Jackson Pollock and William Congdon, the Austrian surrealist Wolfgang Paalen, the sound poet Ada Verdun Howell and the German painter Max Ernst, whom she married in December 1941. She had assembled her collection in only seven years.

Some context: Rosa Luxemburg  (also Rozalia Luxenburg; Polish: Roza Luksemburg; 5 March 1871 - 15 January 1919) was a Polish Marxist theorist, philosopher, economist, anti-war activist, and revolutionary socialist who became a naturalized German citizen at the age of 28. She was, successively, a member of the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), the Social Democratic Party of Germany (SPD), the Independent Social Democratic Party (USPD), and the Communist Party of Germany (KPD). In 1915, after the SPD supported German involvement in World War I, she and Karl Liebknecht co-founded the anti-war Spartacus League (Spartakusbund), which eventually became the KPD. During the November Revolution she co-founded the newspaper Die Rote Fahne ("The Red Flag"), the central organ of the Spartacist movement.
Luxemburg wanted to move to Germany to be at the centre of the party struggle, but she had no way of obtaining permission to remain there indefinitely. In April 1897 she married the son of an old friend, Gustav Lubeck, in order to gain a German citizenship. They never lived together and they formally divorced five years later. She returned briefly to Paris, then moved permanently to Berlin to begin her fight for Eduard Bernstein's constitutional reform movement. Luxemburg hated the stifling conservatism of Berlin. She despised Prussian men and resented what she saw as the grip of urban capitalism on social democracy. In the Social Democratic Party of Germany's women's section she met Clara Zetkin, of whom she made a lifelong friend. Between 1907 and his conscription in 1915 she was involved in a love affair with Clara's younger son, Kostja Zetkin, to which approximately 600 surviving letters (now mostly published) bear testimony. Luxemburg was a member of the uncompromising left-wing of the SPD. Their clear position was that the objectives of liberation for the industrial working class and all minorities could be achieved by revolution only.  The recently published Letters of Rosa Luxemburg shed important light on her life in Germany. As Irene Gammel writes in a review of the English translation of the book in The Globe and Mail: "The three decades covered by the 230 letters in this collection provide the context for her major contributions as a political activist, socialist theorist and writer." Her reputation was tarnished by Joseph Stalin's cynicism in Questions Concerning the History of Bolshevism. In his rewriting of Russian events he placed the blame for the theory of permanent revolution on Luxemburg's shoulders, with faint praise for her attacks on Karl Kautsky, which she commenced in 1910.  According to Gammel, "In her controversial tome of 1913, The Accumulation of Capital, as well as through her work as a co-founder of the radical Spartacus League, Luxemburg helped to shape Germany's young democracy by advancing an international, rather than a nationalist, outlook. This farsightedness partly explains her remarkable popularity as a socialist icon and its continued resonance in movies, novels and memorials dedicated to her life and oeuvre." Gammel also notes that for Luxemburg, "the revolution was a way of life," and yet that the letters also challenge the stereotype of "Red Rosa" as a ruthless fighter. But The Accumulation of Capital sparked angry accusations from the Communist Party of Germany; in 1923 Ruth Fischer and Arkadi Maslow denounced the work as "errors", a derivative work of economic miscalculation known as "spontaneity".
