“The Waltons,” which ran for nine seasons on CBS (1972-81), made Waite a star. TV Guide ranked Papa Walton as TV’s #3 all-time dad in 2004.

With the “Waltons,” Waite became sought-after in TV movies, where he often played against type.

For the past few years, he’s made semi-regular appearances on a variety of shows playing dads and grandfathers on NBC’s “Days of Our Lives” as Father Riggin, on Fox’s “Bones” as Booth’s grandfather and on CBS’ “NCIS” as Jackson Gibbs, dad to Mark Harmon’s character.

When not acting, Waite switched to working behind the scenes as a director.
