Watercolourist, born Marguerite Loeb in Philadelphia, America, into a wealthy family. She attended a finishing school in Switzerland, then studied bookbinding at L’École des Arts Décoratifs, Paris. In Biarritz, in 1925, she met the painter Oskar Kokoschka, who proposed marriage, but her father disapproved and she returned to New York where she studied photography, continued bookbinding and exhibiting. Having in 1929 moved her bindery to Philadelphia, she met the Scottish artist James McBey, marrying him in New York in 1931. They settled in Tangier, Morocco, returning after a World War II sojourn in America, where in western Tangier at El Foolk they established a beautiful garden. After McBey’s death in 1959 Marguerite travelled extensively and developed as a watercolourist, showing in Tangier, New York and at the Fine Art Society, in London where she kept a house and died.
