William Daniels, 95
You’ve probably seen this actor’s face before but can’t quite place where. At 91 years old, he’s had roles in many films and TV shows over the years, including six seasons as Dr. Mark Craig in the medical TV drama St. Elsewhere- which is likely his best-known role to date.
His role in the medical drama earned him two Emmy Awards, and later, he starred in the sitcom Boy Meets World as the school principal, Mr. Feeny.
