Brian Sinclair (veterinary surgeon)

Wallace Brian Vaughan Sinclair (27 September 191513 December 1988) was a British veterinary surgeon who worked for a time with his older brother Donald, and Donald's business partner, Alf Wight. Wight wrote a series of semiautobiographical novels under the pen name James Herriot, with Sinclair and Donald appearing in fictionalised form as brothers Tristan and Siegfried Farnon. The novels were adapted in two films and television series under the name '' All Creatures Great and Small''. Tristan was portrayed as a charming rogue who was still studying veterinary medicine in the early books, constantly having to retake examinations because of his lack of application, often found in the pub, and provoking tirades from his bombastic elder brother Siegfried.

Sinclair studied veterinary medicine at the Royal Veterinary College in Edinburgh. He graduated in 1943 and returned to his brother's practice at 23 Kirkgate in Thirsk, Yorkshire. In the following year, he enlisted in the Royal Army Veterinary Corps and married Sheila Rose, the only daughter of Douglas Seaton, a general practitioner based in Leeds. Shortly after his marriage, he was deployed to Haryana in India, and on demobilisation, he joined the Ministry of Agriculture's Sterility Advisory unit in Inverness, Scotland. In 1950, the ministry offered him a transfer to the Veterinary Investigation Centre in Weetwood Lane, Leeds, a diagnostic laboratory for veterinarians in Yorkshire.

Sinclair retired in 1977 after he had risen to become head of the investigation centre. In retirement, he gave talks on Herriot and Yorkshire, and spoke at veterinary schools in the United Kingdom and the United States. When Wight's first book was published, he was delighted to be captured as Tristan and remained enthusiastic about all Wight's books. He seemed to enjoy being a celebrity and would host informal evenings for tourist groups visiting "Herriot country". He was due to appear as the lead speaker at the annual meeting of the New York State Veterinary Medical Society but he died at Leeds General Infirmary before the meeting could take place.

Early life and education

Sinclair was born at Harrogate on 27September 1915. His father, James, was the son of a crofter who had moved from the Isle of Sanday in the late 19th century. James was said to have been a leather manufacturer but died when Sinclair was just two years old. Sinclair's elder sister, Elsa Vaughan, married Cyril Walter Russell on 5 June 1934 at St Robert's Cathlic Church, Harrogate, where he gave her away. In the 1920s, his elder brother, Donald, was a veterinary student at the Royal School of Veterinary Studies in the University of Edinburgh.

In his youth, Sinclair had considered a career in dentistry, but his interest turned to veterinary medicine after assisting his cousin, then a local veterinarian, with bovine tuberculosis testing. In 1932, he entered the veterinary school at Edinburgh but failed his undergraduate examinations. His brother transferred him to Glasgow Veterinary College but he was expelled after laughing in Professor John William Emslie's pathology class. He finally passed his professional examinations at Edinburgh in December 1943, and in the same month, he was admitted a member of the Royal College of Veterinary Surgeons. He worked for his brother while studying veterinary medicine, and after he graduated, he returned to his brother's practice at 23 Kirkgate in Thirsk, Yorkshire.

Veterinary career

On 23March 1944, Sinclair enlisted in the Royal Army Veterinary Corps (RAVC) and was given the rank of lieutenant. He had been a member of the Edinburgh college Officers' Training Corps (OTC). A month later, on 20April 1944, he married Sheila Rose Seaton, the only daughter of Douglas Seaton, a general practitioner based in Leeds, at StRobert's in Harrogate. Four months after the wedding, he was deployed to the Ambala district in the state of Haryana, India.

Sinclair was put in charge of the mules and camels used by troops in Burma. At the end of the war, he joined India's dairy programme, supervising the care of seventy thousand water buffalo on military farms, and teaching pregnancy testing to local veterinarians. The closest he got to military action was when a local tribe fired shots into the camp using homemade rifles. Alf Wight would write long letters to Sinclair, often twenty pages, that would give news from home and would finish with a description of the Yorkshire countryside. Sinclair would later say that "Reading the erriotbooks I find that the descriptions of the countryside are just the same as in those old letters."

Making the rank of captain, Sinclair was demobilised in 1946. On his return to England, he visited the Ministry of Agriculture, Fisheries and Food (MAFF) headquarters in Surrey in search of a job. He was offered a post at the ministry's Sterility Advisory unit at Church Street, Inverness, in the Scottish Highlands. He and his wife lived at 109Culduthel Road, Inverness, and he travelled around Scotland advising farmers and crofters on livestock fertility. In 1950, the ministry offered him a transfer to the MAFF Veterinary Investigation Centre in Weetwood Lane, Leeds, a diagnostic laboratory for veterinarians in Yorkshire. He had had enjoyed working and living in the Highlands, but decided to accept the transfer to his native Yorkshire, saying later "I would never have accepted any transfer other than one to Yorkshire... I loved the North and Northeast that much."

In 1953, Sinclair and Ken Sellers, a veterinary colleague at the centre, reported a crossspecies infection of ''Salmonella typhimurium'' in shorthorn cows on a farm in Northumberland. The herd was milked in a shed that opened onto a duck house and a pigsty. The pigs, hens, and ducks were all found to be carrying ''Salmonella typhimurium'', although none showed signs of infection. Sinclair and Sellers concluded that the poultry had caused the infection as they had only been recently introduced to the farm. In 1959, he joined the joint MAFF Veterinary Laboratory Services and Public Health Laboratory Services committee on salmonellosis. From 1965 until his retirement in 1977, he was the lead veterinary investigation officer for the centre.

From 1970 to 1974, Sinclair was the advisor to a veterinary clinical trial that attempted to eliminate scrapie from sheep by breeding out susceptibility to it. Scrapie can kill up to twentyfive percent of sheep in an infected flock and there is no known cure. Six sheep farms, located in Yorkshire and Cumberland, were included in the trial. The farmers recorded the offspring of ewes and rams, and if they displayed symptoms of scrapie, then all affected sheep, including their relatives, would be culled from the flock. The detailed recording and culling did have some success as at least one farm was able to declare itself free of scrapie by 1974. He coauthored a number of papers on infections in cattle and sheep, such as Brucellosis and ringworm, but in general, he was not interested in academia. He considered that "having a sense of responsibility to the animal" is the most important value a veterinarian must have.

Literary and dramatic portrayals

When Wight's first book was published, Sinclair was delighted to be captured as Tristan and remained enthusiastic about all Wight's books. He had stated that the Herriot books and television shows were faithful to the truth, although occasionally, the truth was adapted for the purposes of the plot. For example, in ' there is an account of Sinclair letting a car run away and demolishing the local golf club hut. He read this and the next time he met Wight he said "'I don't remember doing that', and he said, 'You didn't it was me.' You see, it didn't fit James Herriot's image in the book, so he put it on to Tristan."

In 2017, Alf Wight's son, Jim Wight, was interviewed and he discussed the James Herriot franchise. He made these comments about Sinclair:

The 1975 film '' All Creatures Great and Small'' was the first adaptation of Wight's semiautobiographical novels of James Herriot. It was directed by Claude Whatham, and starred Simon Ward and Anthony Hopkins as James Herriot and Siegfried Farnon, with Brian Stirner taking the part of Tristan. At the time of filming, Stirner had played the lead role in ''Overlord'', Stuart Cooper's 1975 film about the D-Day landings. From the first film onwards, Wight gave a percentage of his income from film and television rights to Sinclair and his brother. The sequel, ''It Shouldn't Happen to a Vet'', premiered in 1976, but did not feature a Tristan character.
