Caveat: The above dates represent the best estimates. Neither Bessie nor Boris Thomashefsky’s memoirs contain dates. We began with Zalmen Zylbercweig’s entries in his Lexicon of Yiddish Theatre, then reconciled his dates with events described in the autobiographies, newspaper articles, copyright registrations and numerous other documents.
