Conrad Bain, the easygoing TV star who played the Park Avenue father on the 1978-85 sitcom Diff’rent Strokes, died in his hometown of Livermore, Calif., on Monday. He was 89.

His daughter, Jennifer Bain, confirmed his death to PEOPLE, and said her father died of natural causes.

“He’d been unconscious for a couple of days, but he was comfortable and it was very peaceful,” she said of her dad, who also played the argumentative neighbor on the 1972-78 hit show Maude.
