Late Sunday night, ears of the faithful "Night People" throughout the city perked up at the introduction of Dr. Sholem Stein, "CCNY Professor" on the Jean Shepherd WOR radio show. Dr. Stein was introduced on a tape recording as "Professor of Hebrew at the City College of New York" and an "authority on the origins of calypso." The hundreds of students flipping through the pages of the College Bulletin in search of the professor's name met with disappointment. It wasn't there.
