Among the members of the German "Irving Place Theatre", which Maurice Schwartz had attempted to [aribertsyen] in his Yiddish troupe, which had taken over the theatre, the Christian-German actor Hans Unterkisher was found, who on 28 November 1918 performed there as "Apollo" in the production of Jacob Gordin's "Sappho" with Berta Gerstin in the title role.

B. Gorin writes:

"There debuted [nokh] other Germans at the Irving Place Theatre, but they acted in German, and, when Rudolph Kristian, they did not accept Yiddish theatre."
