Marguerite Guggenheim was born in a wealthy and famed New York family, who, following her father's death – sipping a glass on the deck in his best clothes - on the Titanic as well as her grandfather's, becomes a rich young heiress, in 1919. Settled in Paris, in 1921, Peggy Guggenheim marries Laurence Vail and soon becomes friends with major figures of modern art such as Marcel Duchamp who advises her, alongside Jean Cocteau, for the opening of her art gallery in London, in 1938. Influenced by the artists she meets, Peggy Guggenheim becomes a passionate collector who accumulates pieces by Vladimir Kandinsky, Constantin Brancusi, Hans Arp or Victor Brauner. During World War II, she fights to protect her collection, helps her friends escape an occupied France and marries, in 1942, Max Ernst, partly to help him settle in New York with her. The same year, she opens a new gallery in the city that focuses on European abstract art before turning herself towards young American artists such as Mark Rothko and Jackson Pollock. In 1949, she settles in Venice where she presents her collection in a palace facing the Grand Canal – a site that becomes a veritable museum in 1952. An eccentric accused of being a nymphomaniac and mocked for her unpleasant features - 'She was remarkably ugly, in such a pleasant way' – Peggy Guggenheim nonetheless remains a visionary who from complete ignorant became the maker of one of the 20th century most incredible art collection.
