Tom Bosley, who starred on Happy Days as Mr. Cunningham, has died. He was 83. Bosley’s co-stars remember him fondly; Scott Baio said of his older castmate, "He was a good man who taught me a lot about the business and business itself. He was a professional guy ... I'm sad." Henry Winkler added that he was happy he got to work with the actor for a decade. “Tom Bosley was our mentor,” Winkler said. “He was a true artist ... a great husband, and a fabulous father and grandfather. He will be sorely missed, but never forgotten."
