玛丽安·奥斯瓦尔德，Marianne Oswald was the stage name of Sarah Alice Bloch, a French singer and actress born in Sarreguemines in Alsace-Lorraine. She took this stage name from a character she much admired, the unhappy Oswald in the Ibsen play Ghosts. She was noted for her hoarse voice, heavy half-Lorraine, half-German accent, and for singing about unrequited love, despair, sadness, and death. She sang the songs of Kurt Weill and Bertolt Brecht. She was friends with Jean Cocteau, Jacques Prévert, François Mauriac, and Albert Camus. In fact, the text for one of her album covers was written by Camus. She was an inspiration for the composers Francis Poulenc and Arthur Honegger.
