The mystery man is Peter Bonerz, 87, best remembered as eccentric orthodontist Dr. Jerry Robinson on The Bob Newhart Show. He was seen with his wife, Rosalind DiTrapani, whom he married in 1963.
Bonerz looked relaxed and in good spirits, while Rosalind wore a white top and navy trousers. Their low-key walk contrasted sharply with the fast-moving television world in which he built his career.
From 1972 to 1978, he became a familiar face in American homes as Bob Hartley’s friend and office colleague. His comic timing made Jerry a fan favorite, but acting was only part of his contribution: Bonerz also directed 29 episodes.
Behind the camera, his influence grew larger. Across several decades, he directed more than 350 television episodes, working on Murphy Brown, Home Improvement, ALF, Wings, NewsRadio and Friends. He guided 12 episodes of Friends, helping shape a comedy watched around the world.
Born in New Hampshire and raised in Milwaukee, Bonerz graduated from Marquette University in 1960, served in the US Army and honed his skills in improvisational theater. Before sitcom fame, he appeared in The Addams Family, Hawaii Five-O, Medium Cool and Catch-22.
After Bob Newhart’s death in 2024, Bonerz became the last surviving principal cast member of The Bob Newhart Show. That gives the outing extra meaning: the quietly dressed man on the sidewalk is also a living link to a cherished era of television.
Though he left Hollywood’s daily spotlight years ago, his work remains visible in classic reruns and beloved sitcom scenes. For viewers struggling to place his face, the answer reveals a remarkable career hiding in plain sight.
