Brian Sinclair

Wallace Brian Vaughan Sinclair (27 Sep 1915 - 13 December 1988), universally known as Brian, was a British veterinary surgeon who worked for a time with his elder brother Donald and Alf Wight (better known as 'James Herriot') although he spent the majority of his working life employed by the Ministry of Agriculture. He was the model for the character 'Tristan Farnon' in Wight's semi-autobiographical novels, which were later adapted to the big screen in three films, and television under the name All Creatures Great and Small. He graduated from the University of Edinburgh Veterinary School.

Unlike his elder brother, who for some time, saw the books as a great trial of his friendship with Wight, Brian made no objections to Wight's ne'er-do-well portrayal of him, and in fact seemed rather to enjoy the celebrity.
