Fans of the 1970s television drama The Waltons were saddened to learn of the passing of Ralph Waite on Thursday at age 85. For nine seasons the actor played John Walton, Sr., a father of seven struggling to make ends meet during the Great Depression and World War II.

“[Fans] tell me that I was their surrogate father, the one who brought them up,” Waite told Entertainment Weekly last year.

Indeed, Waite’s honest portrayal struck a chord with audiences around the world, and left a big impression on actor Richard Thomas, who played eldest son John-Boy on the series.

“I loved Ralph very much. He was a kind and funny man with a great social consciousness and a big heart,” Thomas tells PEOPLE. “And he was one of the most uncompromisingly honest men and actors I’ve ever known – a great example for a young performer. Goodnight, Daddy.”

In addition to The Waltons, Waite appeared in Alex Haley’s miniseries Roots, and had recurring roles on the soap opera Days of Our Lives and the hit CBS drama NCIS.

Here’s what the rest of The Waltons cast has been up to:

Michael Learned (Olivia Walton): Toured with a stage production of Driving Miss Daisy and appeared in the independent film Afterlife.
