Nahum Meïr Schaikewitz,[1] also known by his pseudonym "Shomer" (December 18, 1849 in Nesvizh, Russian Empire – 25 November 1905 in New York City)[2] was a Yiddish and Hebrew novelist and playwright. Although he was very popular in his time and a giant in Yiddish literature, sometimes styled the "Dumas of Yiddish literature",[2] he was significantly damaged by Sholem Aleichem, who derided his plotting as extravagantly artificial and improbable, characteristic of a cheap potboiler.[3]
