Sholem Stein (born August 28, 1938 in New York City) is a fictional scholar.
Henry Jacobs often brought experts in certain ethnic music onto the show to provide background information. When no experts were available, he would not infrequently fake it - most notably in the case of "Sholem Stein", a putative Hebrew musicologist who claimed that calypso music had deep Rabbinical meanings.
He was possibly voiced by Lenny Bruce.
