Alma Manon Gropius (October 5, 1916 – April 22, 1935) was the daughter of the architect Walter Gropius and the composer and diarist Alma Mahler and the stepdaughter of the novelist and poet Franz Werfel. She is a Randfigur (peripheral person) whose importance lies in her key relationships to major figures: a muse who inspired the composer Alban Berg as well as Werfel and the Nobel Prize-winning writer Elias Canetti.
