Jacob Gordin was at the head of a more serious school of Jewish dramatists in America, whose effort to introduce――also by translations and adaptations――the problem-play, the psychological play and the realistic play, on the Yiddish stage, began a new epoch, which is now practically ended. His good style and technique insured for some of his pieces a considerable popularity for a time, and they are now much played in the revived Yiddish theater of Russia. Z. Libin and L. Kobrin were for a time his most consistent followers, and several other literary men have attempted to follow in his footsteps. But aside from the temporary popularity of some plays, the school itself, which was founded on Russian ideals and conceptions, could not take root here. Bernhard Gorin and David Pinski have also written plays that possess literary merit, and so have several others who cannot be classed as followers of the new school. The most talented actors and actresses of the original troupes which the founder of the Yiddish theater, Goldfaden, organized in Roumania, Russia and later in Austria, came to this country at various periods during the last three decades. They, together with other able players and managers who learned much from their American colleagues, have brought the Yiddish stage here to a higher state of development than it has reached in other countries. The most prominent among them are Jacob P. Adler (b. in Odessa, 1855; a. 1886) and his wife, Sarah; Sigmund Mogulesco (b. in Bessarabia, 1858), who arrived about the same time; Mrs. K. Lipzin; Mrs. Bertha Kalich, who has left the Yiddish for the American stage; Boris Thomashefsky (b. in Kiev, 1866; a. 1881) and his wife, Bessie; David Kessler, Regina Prager Mme. Lobel, Bernhard Bernstein, Moskovich, Thornberg (d. 1911), Mrs. Epstein, Mrs. Abramowich, Blank, Glickman, Fishkind, Graf, Gold, Mr. and Mrs. Tobias, Mr. and Mrs. Tanzman, and others. Moritz Morrison, the German actor, occasionally appears on the Yiddish stage, and lately Rudolph Schildkraut, a native of Roumania, who was for some years prominent on the German stage in Europe, has settled as a Yiddish actor in New York.
