During this period he also undertook the major novels "Arnold Levenberg: Der Tserisener Mentsh" ("Arnold Levenberg: The Split Personality", begun 1919) and "The House of Noah Edon" which was published in English translation in 1929; the Yiddish original was published in 1938 by the Wydawnictvo ("Publishers") Ch. Brzozo, Warsaw. The former centers on an Uptown, aristocratic German Jew, who is portrayed as an overefined and decadent, crossing paths with, but never fully participating in, the important events and currents of his time. The latter is a multi-generational saga of a Lithuanian Jewish immigrant family, an interpretation of assimilation modeled on Peretz's "Four Generations—Four Testaments".
