During his years in Berlin, Piscator had collaborated with Lena Goldschmidt on a stage adaptation of Theodore Dreiser's bestselling novel "An American Tragedy"; under the title "The Case of Clyde Griffiths". With American Lee Strasberg as director, it had run for 19 performances on Broadway in 1936. When Piscator and Ley subsequently immigrated to the United States in 1939, Piscator was invited by Alvin Johnson, the founding president of The New School, to establish a theatre workshop. Among Piscator's students at this Dramatic Workshop in New York were Bea Arthur, Harry Belafonte, Marlon Brando, Tony Curtis, Ben Gazzara, Judith Malina, Walter Matthau, Rod Steiger, Elaine Stritch, Eli Wallach, Jack Creley, and Tennessee Williams.
