William Daniels built a remarkable entertainment career that allowed him to become familiar to audiences of very different ages. For many fans, one of his most memorable roles was the voice of KITT, the intelligent car from Knight Rider. Through his calm and distinctive delivery, Daniels gave the fictional vehicle a personality of its own, helping KITT become one of television’s most recognizable characters.

Years later, Daniels reached another generation through Boy Meets World, where he played George Feeny, the thoughtful teacher and mentor. Mr. Feeny offered guidance far beyond the classroom, becoming a steady presence as the young characters faced friendships, relationships, and difficult choices. The role showed Daniels’ ability to bring warmth and sincerity to a character while still allowing room for humor.

What made Daniels’ career especially notable was its variety. He worked across television, film, theater, comedy, drama, and voice acting, creating memorable performances without being limited to one particular type of role. His long marriage to actress Bonnie Bartlett also became part of his personal story, with the couple sharing decades together while building careers and a family life in entertainment.
