Arnaud d'Usseau (April 18, 1916 – January 29, 1990) was a playwright and B-movie screenwriter who is perhaps best remembered today for his collaboration with Dorothy Parker on the play The Ladies of the Corridor.
He first came to notice as the co-writer (with James Gow) of Tomorrow, the World!, a 1943 drama about a German boy adopted by an American couple who then have to struggle with his Nazi upbringing.
In 1945, another controversial play by D'Usseau and Gow followed, Deep Are the Roots, about a black army officer who falls in love with a former Senator's daughter.
It ran for 477 performances over 14 months, directed by Elia Kazan and starring Barbara Bel Geddes and Gordon Heath.
Upon returning to the United States, he taught screenwriting at New York University and the School of Visual Arts.
