In 1923 the entire cast of a Yiddish play was arrested in New York and charged with staging an immoral performance. Written by the celebrated Polish-Jewish writer Sholem Asch, 'God of Vengeance' is set in a brothel and deals with themes such as prostitution, religion and corruption. David Mazower, the playwright's great-grandson, speaks about the controversy. (Photo: Sholem Asch, left, with Russian playwright Maxim Gorky,1920s. Courtesy of David Mazower)
