On 14 January 1895 his play "Eliahu hanovi, or, Aristobulus melekh yehudah (Elijah the Prophet, or King Aristobulus of the Jews)," a historical operetta in five acts and a prologue, written in programs, was staged the first time by the Juvelier troupe in Bucharest.

The anonymous critic from Bucharest’s "Folksblat" wrote about the play and author. "We must, however, know that this young author has no grounded experience and mature theatre knowledge in order to make so many excuses. The critic here is long in the tooth and has no place. We must agree that the young writer has talent and has for the first time shown us that we can use our own history in the best manner. He must be able to write in a clear, pure language. …Hoping that this is correct, our Mr. Katz who knows the art of the Yiddish theatre will correct some of the holes in his play such as "Di tsente gebot (The Tenth Commandment), or, "You Should Not Envy," by Abraham Goldfaden, "Di farblonjete neshome (The Lost Soul)" (by Joseph Latayner), "Meshiekh’s tsaytn" (Arrival of the Messiah) (by Avraham Goldfaden) etc., and not be driven out of the theatre.

According to Kalman Juvelier, the author of the operetta was a local intelligent younger man. The music to the operetta, which even was performed several times, was composed by Arnold Perlmutter. In the offering, there participated: Kalman Juvelier, Yetta Reich, Shmuel-Ber Ferkauf, A. Shrage, Yekutiel Margoles and I. Giltman.

About the productions of K.'s other plays anywhere, nothing is known, nor is there any news of it.

M.E. from Kalman Juvelier.
