Donald Vaughan Sinclair (22 April 1911 – 28 June 1995) was a British veterinary surgeon (graduated from the Royal (Dick) School of Veterinary Studies, 1933) made famous as the eccentric character Siegfried Farnon in the semi-autobiographical books of James Herriot (Alf Wight), later adapted for film and television as All Creatures Great and Small.

Early life and veterinary career

He was the son of Margretta née Vaughan and James Sinclair, a leather goods manufacturer who died in his adolescence, and studied to be a veterinary surgeon in Edinburgh, as his future friend and colleague James Alfred ('Alf') Wight (alias James Herriot) was similarly so studying in Glasgow. Although never referenced in the Herriot fiction series, the autobiography acknowledges the early death of his first wife, Evelyn Beatrice Sinclair née Holborow. They married at St. Giles, Edinburgh, on 4 November 1930, both aged 19 years and after his graduation, the couple moved to live in the West Riding of Yorkshire. In 1936, aged only 24 years, Evelyn Sinclair died of bovine brucellosis transmitted by contaminated milk, three years before he purchased the Kirkgate property that was made famous in the Herriot series. The couple had no children. Sinclair had a son, Alan Donald, and a daughter, Janet, with his second wife Audrey née Adamson in 1944. There are several internet references to the fact that Sinclair was also Master of the now disbanded (1987) Wensleydale Harriers

Royal Air Force service

In 1939, he bought an existing veterinary practice at 23 Kirkgate, Thirsk, Yorkshire, and in July 1940 hired Wight to run it while he (Sinclair) was undertaking his war service in the Royal Air Force. However, Sinclair had deliberately misrepresented himself as being younger than he was in order to join up, and it was quickly discovered that his reflexes were not fast enough for him to continue with pilot training. He could have been redeployed within the service, but the fact that he was a veterinary surgeon (a reserved occupation) meant that he was considered more useful to the war effort by resuming his peacetime profession. The severe national food shortage meant that proper veterinary treatment of farm animals received a very high priority, and so within four months of joining the RAF he received a compulsory discharge and he returned to Thirsk.

Literary caricature

The fictional character Siegfried Farnon is portrayed as outspoken, opinionated, bossy, quick to lose his temper, and also quick to "blow over" — in short, bombastic. He is nonetheless basically good-hearted and an animal lover, fond of riding, and infuriated by any suspicion of deliberate cruelty to animals. One recurrent theme in Herriot's stories was Siegfried's criticism of James's flaws, such as forgetting appointments or leaving tools behind after calls, only for the reader to find that Siegfried is found guilty of the same things.

When Wight's first book was published, Donald was apparently most offended by his portrayal, saying "Alfred, this book is a real test of our friendship." (He never called Wight 'Alf' - mirrored in the books by Siegfried always referring to Herriot as "James" rather than "Jim".) Things calmed down, however, and the pair continued to work together until they retired. Opinion is divided as to whether Sinclair was as eccentric in reality as Siegfried was portrayed in the books, but it seems likely that even if his character was exaggerated, he was unique. Sinclair always refused to accept he was eccentric. However, former clients and colleagues, as well as Alfred Wight's own son in the book The Real James Herriot, stated that Sinclair's character in the novels was considerably toned down and that Sinclair was even more eccentric than the Herriot books portrayed.


Sinclair took his own life by an overdose of barbiturate on 28 June 1995 at his home Southwoods Hall, near Thirsk, two weeks after the death of his second wife Audrey (née Adamson), to whom he had been married for fifty-three years. His brother Brian ('Tristan' in the books) had died several years earlier, and his friend and partner, Alf Wight, only four months previously.
