Douglas Wilmer, best known for his portrayal of fictional British detective Sherlock Holmes, died on 31 March. The actor played the character created by Sir Arthur Conan Doyle in the 1960s BBC series.

According to Roger Johnson, a spokesman for the Sherlock Holmes Society Of London, Wilmer passed away in a hospital in Ipswich after a bout of pneumonia. "He was a great actor, he was a gentleman, he had a long and distinguished career," Johnson said.

Wilmer first made his appearance as the deerstalker-wearing sleuth in 1964, with Nigel Stock playing the role of Dr Watson in The Speckled Band. He went on to work in 12 episodes of the Sherlock Holmes series.

Even after leaving the show, the actor continued to be associated with his most famous character. In 1973, he played Professor Van Dusen in The Rivals of Sherlock Holmes and in 1975 he once again turned private detective in a supporting role in The Adventure Of Sherlock Holmes' Smarter Brother.

And in 2012, at the very end of his acting career, he made a cameo appearance in an episode of the Benedict Cumberbatch-starrer Sherlock as an irate old man at The Diogenes Club.

Mark Gatiss who plays Mycroft, Sherlock's older brother on the current show, shared a photograph of himself with Wilmer on Twitter with the caption: "An honour to have known dear Douglas Wilmer. A Sherlock for all seasons. The work was something, the man was all. RIP."

Aside from his detective role, Wilmer also acted in the James Bond film Octopussy, Jason And The Argonauts, the Pink Panther films and The Golden Voyage Of Sinbad.
