In 1889 Shomer was persuaded to go to the U.S. where his plays were being successfully performed. Here, too, he achieved enormous popularity, producing novels for newspapers and plays at a phenomenal pace. He also edited several magazines and festival publications, filling them largely with his own novels, short stories, and journalistic material. Through his works Shomer led the Yiddish-reading masses into the magic world of fantastic events and exciting developments where good always triumphed over evil. He was convinced that his books performed the valuable function of bringing ethical education to the Jewish masses whose general education had been neglected. Indeed, Soviet critics later emphasized the educational service performed by Shomer's narratives in the struggle to improve the lot of the Jewish victims of poverty and oppression. Of his more than 100 novels and plays, at least a dozen have retained their popularity and have been repeatedly reprinted. Among his works are Di Ungliklikhe Libe (1882); Der Oytzer oder der Kalter Gazlen (1884); Eyn Ungerikhter Glik (1885); Der Yid un di Grefin (1892).
