Moses Horowitz

[3] Jacob Adler describes him as an "authorit[y] on dramaturgy", but also remarks that before being part of the Yiddish theater in London in the mid-1880s he had "wandered in different lands, involved himself in various undertakings, and then moved on often leaving, it is said not altogether pleasant memories behind him."

[5] At age eighteen, he became a Hebrew teacher in Iaşi, Romania, before moving to Bucharest, where he became director of a Jewish school, a position from which he was dismissed, after which he converted from Judaism to Christianity and became a missionary.

[5] At the Roumanian Opera House, he presented Tisa Eslar, oder, Di Farshverung, a play he had already written in Romania about the 1882 blood libel trial in the Hungarian town of Tiszaeszlar; he also produced a sequel, Der Protses in Tisa Eslar ("The trial in Tiszaeszlar").

According to the Jewish Encyclopedia, among his more successful plays are: Schlome Chochom, Kuzri, Chochmath Noshim, Ben Hador, and Jizius Mizrujym.

After the success of his 1904 play Ben Hador, he lost all of his money on an unsuccessful venture in 1905 to present grand opera in Yiddish at the Windsor Theatre, on the Bowery;[9] shortly after that, he was stricken with paralysis, and lived out his last years in the Montefiore Home, provided for by his friends.
