Scriptwriter and producer Brian Clemens OBE has died aged 83.
Clemens, who created 60s and 70s favourites The Avengers, New Avengers and The Professionals, passed away on Saturday, his family have confirmed.
During his long career Clemens also worked on Bergerac, The Baron, The Persuaders, Father Dowling Mysteries, The Adventurer, The Protectors, Diagnosis Murder and The Invisible Man.
Clemens was made an OBE by the Queen in 2010 for services to broadcasting and drama. “I am pleased from the point of view of all screenwriters,” he said at the time. “It is an encouragement to the backroom boys – I count myself as one.”
“He was a true inspiration. The world has lost a really great man who has given so much,” his son George Clemens told the BBC.
Colleagues, fans and friends, including Sherlock scribe Mark Gatiss, have taken to Twitter to pay tribute to the writer.
Brian Clemens had more great ideas than almost any other TV writer. His mantra was wonderfully simple – "Arse to chair, pen to paper". RIP.
