Brian Sinclair (veterinary surgeon) Ministry of Agriculture's Sterility Advisory unit, rising to become head of the Veterinary Investigation Centre in Leeds. He was the model for the character 'Tristan Farnon' in Wight's semi-autobiographical novels, which were later adapted to the big screen in two films, and television under the name "All Creatures Great and Small". The fictional Tristan was portrayed as a charming rogue who was still studying veterinary medicine in the early books, constantly having to re-take examinations because of his lack of application, often to be found in the pub, and subject to tirades from his bombastic elder brother Siegfried. Unlike his
All Creatures Great and Small (TV series) penchant for sleeping late, failing his exams, and spending too much time chasing women. In the episode "The Prodigal Returns", when Siegfried mistakenly thinks "little brother" is impersonating a client on the other end of the telephone line, a few home truths come out: "Mr Biggins, if you've got it into your head that young Mr Farnon is a veterinary surgeon of any quality whatsoever, let me disabuse you of that idea immediately. He is nothing more than a slothful, drunken, incompetent lecher who will soon be seeking employment elsewhere." Tristan's party piece is a rendition of "The Mad Conductor"
