Lawson was fascinated by the works he saw when in 1926 the New York International Theatrical Exposition showcased experimental European cubist, futurist, and constructivist plays. After seeing these, Lawson, Dos Passos, and Michael Gold (founder/editor of "The New Masses" magazine) formed the Workers Drama League to produce revolutionary plays. One production and a few weeks later, the three men disbanded. They joined Em Jo Basshe and Francis Edward Faragoh, and formed the New Playwrights Theatre. This lasted until 1929; they were supported largely by funding from millionaire businessman Otto Hermann Kahn.
