From Wikipedia Maurice Cass was a character actor in numerous films and television shows. Born in Lithuania, he came to the US to pursue an acting career. His slight build, frizzy hair and pince-nez glasses cast him as the "absent minded professor" or eccentric scientist type in many of his films, such as the character who discovers the element kryptonite in Adventures of Superman. He is best remembered for his role as Professor Newton in the 1954 TV science fiction series Rocky Jones, Space Ranger.
