Later on, he began his career in Hollywood in the early 70s with guest roles on episodes of “Sanford and Son,” “Hawaii Five-O” and “All in the Family.” A few years later, he nabbed his breakout role in 1975 on the police comedy “Barney Miller,” which earned Glass a Primetime Emmy nomination in 1982 in the supporting actor category, the report say.
