Dr Tynan is a character in the James Bond film and novel Diamonds Are Forever. He is portrayed by Henry Rowland.
Tynan is a South African dentist who is the first link in the diamond smuggling pipeline. He extracts diamonds from the mouths of miners and ships them out of the country. In both versions of the story, he is met by Wint and Kidd, who pick up the diamonds from him. Kidd complains of a toothache, and when Tynan bends over to check Kidd’s mouth, Wint drops a scorpion down the back of his shirt (in the film’s alternative version, it was shoved up his mouth) , envenomating Tynan within seconds. When smuggler and helicopter pilot Joe meets Wint and Kidd, the former tells Joe that Tynan was “bitten by the bug.”
