Written in 1930 in Warsaw by Aaron Zeitlin, a leading Yiddish poet and playwright, the play Jacob Jacobson stunned Yiddish cultural circles with its modernity. Imbued with mysticism and religiosity, the play also exposed itself to accusations of conservatism. With biting pessimism, it dared to predict the outbreak of a second world war, a senseless repetition of the carnage of 1914-1918.
