Isidor Goldenberg

was a Romanian Jewish singer and actor, prominent in Yiddish theater in the late 19th and early 20th century.

In Galaţi he spent a summer performing in one of the garden theaters common at the time, then worked with a singer named Solomonescu, before hooking up with the troupe of Marcu Segalescu, in which he played small roles.

[1] He performed with Axelrod in Lviv from 1889 to 1891, then in Budapest with Josef Eskraiz, Shramek, and Veinstock, back to Lviv where he played in several Goldfaden plays Rabbi Yosselmann, The Tenth Commandment, Judith and Holofernes and Baron Rothschild.

Beginning in 1904, he had great success with the more naturalistic repertoire of Jacob Gordin; in 1906 he played in one of the many Yiddish productions of Karl Gutzkow's Uriel Acosta, before heading to New York City, where he performed with Jacob Adler, Boris Thomashefsky, Max Morrison, and others.

He returned to Europe and, in 1913, upon the death of Moritz Lieblich,[2] became the director of the Jigniţa, which throughout World War I was a highlight of the distressed wartime Bucharest theater scene.
