John Leeson, Voice of K9 on ‘Doctor Who,’ Dies at 83

John Leeson, the English actor best known for voicing K9, the beloved robot dog on the long-running BBC series “Doctor Who,” died on Sunday at the age of 83. His son, Guy Ducker, confirmed the news in a Facebook post, noting that Leeson passed away at 3:03 p.m. after a summer of illness. Leeson’s portrayal of K9, with its distinctive, slightly pompous but endearing voice, became a fan favorite from the character’s debut in 1977 alongside Tom Baker’s Fourth Doctor. He continued to voice K9 across multiple eras of the show, including the modern revival, and in spin-offs like “The Sarah Jane Adventures” and the standalone “K9” series. Beyond “Doctor Who,” Leeson had a varied career in British television, appearing in shows such as “Dad’s Army” and “Blake’s 7,” but it was his work as K9 that earned him a lasting place in science fiction history. The character remains one of the most iconic non-human companions in the franchise’s 60-year history. Leeson’s death marks the loss of a distinctive voice that brought joy to generations of “Doctor Who” fans. His legacy as K9 endures in the hearts of viewers and in the continuing adventures of the Doctor.
