He played Grandpa Munster on the TV series "The Munsters" and Leo Schnauzer in the TV series "Car 54, Where Are You?" Note: Although the claim has been made (mainly by Al Lewis) that he was born in 1910, all the evidence points to his year of birth being 1923. According to A&E's "Biography" episode about his life, his mother didn't even arrive in this country until 1913 (at age 16) and his parents weren't married until 1922.
