The world of television has lost one of its great comedic treasures. David Ketchum, the actor, comedian, and writer best remembered for his scene-stealing role as Agent 13 on Get Smart, passed away on August 10, 2025, at the age of 97. His career stretched across decades of television history, marking him as both a beloved performer and a gifted writer whose humor shaped a generation of entertainment.
Born in Quincy, Illinois, in 1928, Ketchum discovered early on that he had a gift for timing, wordplay, and character comedy. After moving to Hollywood in the early 1960s, he quickly established himself in an era when sitcoms were at the center of American popular culture. His sharp wit and versatile acting ability landed him appearances on popular shows like I’m Dickens, He’s Fenster, The Mary Tyler Moore Show, and Camp Runamuck, where he played the quirky character Spiffy.
But it was his role as Agent 13 in Mel Brooks and Buck Henry’s satirical spy comedy Get Smart that secured his place in television history. Agent 13, the perpetually unlucky secret agent squeezed into mailboxes, lockers, and vending machines for surveillance duty, became a fan favorite. With his signature deadpan delivery and knack for physical comedy, Ketchum turned what could have been a forgettable side character into one of the show’s most memorable running gags. His brief appearances consistently stole scenes, proving that even a few seconds of screen time could leave a lasting impression when handled by the right actor.
Ketchum reprised the role years later in the 1989 television film Get Smart Again! and again in the short-lived 1995 Fox revival of the series. Each time, he managed to introduce his comedic genius to a new generation of viewers, demonstrating the timelessness of both the character and his performance.
Beyond acting, Ketchum was a prolific writer whose contributions behind the camera were equally significant. His pen helped craft episodes for some of the most beloved series in television history, including MASH*, I Dream of Jeannie, The Six Million Dollar Man, Wonder Woman, The Bionic Woman, Laverne & Shirley, The Love Boat, MacGyver, and Full House. His writing style combined sharp humor with an understanding of character dynamics, elevating the shows he touched and ensuring their enduring appeal.
In interviews, colleagues often described Ketchum as a quiet force of creativity—someone who didn’t crave the spotlight but who consistently delivered laughter and warmth through his work. While audiences remembered his physical comedy and iconic roles, those who worked alongside him cherished his generosity, intelligence, and genuine kindness.
