The entertainment industry is mourning the loss of John Leeson, the veteran actor celebrated for providing the voice of the iconic robotic dog K9 in the long-running science fiction series Doctor Who. Leeson, born John Ducker, passed away peacefully on November 1 at the age of 83 following a period of illness throughout the summer.
His son, Guy Ducker, shared the news of his father's passing on social media, expressing the family's grief while noting that his father’s final moments were tranquil. “I regret to announce the death of my father, John Ducker, a.k.a. John Leeson, at 3:03pm today after a summer of illness,” he wrote. “The end was peaceful. Good night sweet prince: And flights of angels sing thee to thy rest!”
Leeson’s career in the arts spanned several decades, beginning with his early work in theater as a child in his native England. Throughout his prolific career, which lasted from the late 1960s through 2010, he appeared in a diverse range of television and film projects. His television credits included roles in the children's program Rainbow, as well as appearances in The Sarah Jane Adventures, Bugs, and Beadle's About. On the big screen, he was featured in the 1979 film Tarka the Otter and the 1988 martial arts movie Miami Connection.
However, he is most fondly remembered by legions of fans for his portrayal of K9. When Russell T. Davies, the showrunner who spearheaded the revival of Doctor Who in the mid-2000s, brought the character back in 2006, he noted that Leeson was the only choice for the role.
Reflecting on the actor's legacy, Davies paid tribute to Leeson’s unique ability to bring depth to a mechanical character. “When we brought K9 back in 2006, there was no question that we’d ask John to provide the voice, it was impossible to imagine anyone else,” Davies shared on Instagram. “And really, what a performance, what a character: a posh dog, uppity, haughty, wry, but somehow innocent too, and so funny. ‘Maximum defence mode!’ God he was good. Pitched perfectly so that kids could impersonate him. That’s not easy, that’s hell of a piece of acting. And he was wonderfully dedicated to that character for… gasp, six decades!”
John Leeson is survived by his wife, Judy, and his son.
