In short: Brian Sinclair, the charming rogue behind the fictional Tristan Farnon in the All Creatures Great and Small series, led a life as colorful as his literary counterpart. Beyond the pub-frequenting student depicted in books, he was a dedicated veterinary investigator who became an international ambassador for his profession.

Born in Harrogate in 1915, Brian Sinclair followed his brother Donald into veterinary medicine, though his path was marked by academic struggles and a legendary sense of humor. While his brother and business partner Alf Wight—who wrote under the pen name James Herriot—portrayed him as a perpetually failing student, Sinclair eventually qualified in 1943. His early career included a wartime stint in the Royal Army Veterinary Corps, where he managed thousands of water buffalo in India, before he returned to Britain to join the Ministry of Agriculture’s diagnostic services.

Sinclair’s professional legacy was rooted in his work at the Veterinary Investigation Centre in Leeds, where he rose to become head of the facility. He contributed to significant research on animal health, including studies on Salmonella typhimurium and clinical trials aimed at eliminating scrapie in sheep. Despite his scientific contributions, he remained humble, often stating that a sense of responsibility toward animals was the most vital trait for any veterinarian. He maintained a lifelong friendship with Wight, even as the latter’s books turned their private lives into global cultural phenomena.

In his later years, Sinclair embraced his fame as the inspiration for Tristan Farnon. He became a popular speaker, touring the United States and the British Empire to discuss veterinary medicine and the world of Herriot. His influence extended to the actors who portrayed him; Peter Davison, who played Tristan in the BBC series, found meeting Sinclair essential to capturing the character’s endearing nature. Sinclair passed away in 1988 at the age of 73, remembered by friends as a dependable, sound man beneath his hilarious, public-facing veneer.
