According to Itzhak Libresko, D. was a Lemberger and when Goldfaden had forced him to become a tenor, he sent him to Bucharest [tsukermanen, velkher hot im, gevezenem] a choirboy, he was brought in the troupe. As a singer, D. excelled and had really charmed the audience, but as an actor he used to receive "lump fever" and therefore after a short time left the stage.

Zigmund Mogulesko related in his memoirs ("Forward", 1906) that "D. had sung together with him for Cantor Kuper, and afterwards studied together in the conservatory, where they had come to receive a proposal to [shmdn] and was taken in to perform in the Rumanian theatre. D. had a Caruso voice. Rich, filled with metal and with gentleness, it was just a rarity. When he had left the opera stage, it would be with him that the world succeeded."

According to Cesar Greenberg, D. wasn't ordered Dilman, but Dilman. Goldfaden had created for him a specially written role in "Nye be, nye me". D. acted for several months with Goldfaden, but he was [antoysht], so he left the stage and went away to study music in Vienna, where he later was a cantor.
