Aaron Zeitlin (3 June 1898 – 28 September 1973), born in Uvarovichi, Russia (now Belarus), was a Jewish American educator and writer. He authored several books on Yiddish literature, poetry and parapsychology. He spent his formative years in Gomel and Vilna. In 1920, he and his brother Elchanan traveled to Palestine, and in 1921 they returned to Eastern Europe, settling in Warsaw. Zeitlin's literary abilities were apparent already in his youth when he contributed some articles to the Odessa-based children's journal Perachim and Hashachar. His first publication was a fictional piece that appeared in the journal Di yidishe velt (די ייִדישע װעלט "The Jewish World"), in 1914. His first published books of Yiddish poetry were Metatron (1922) and Shotns oyfn shney (Shadows on Snow; 1923). In the 1920s to 1930s, he published short stories, as well as many philosophical and journalistic essays, and pieces of literary and cultural criticism. In 1939, Zeitlin accepted an invitation from Maurice Schwartz, the director of the Yiddish Art Theatre, to come to New York to work on the company's production of his play Esterke. Prevented from returning home by the beginning of the World War Ⅱ, Zeitlin settled in New York permanently. His play Chelmer Chachomim (the "Wise Men of Chelm") had already opened to critical acclaim at the Yiddish Theatre in New York prior to his arrival, and he slowly became a fixture of the Yiddish scene. For a time, he was also Professor of Hebrew literature at the Jewish Theological Seminary of America, in New York.
