Marguerite "Peggy" Guggenheim 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. The Peggy Guggenheim Collection is a modern art museum on the Grand Canal in Venice, Italy, and is one of the most visited attractions in Venice.
