James Herriot is the pen name of James Alfred Wight, an English veterinary surgeon and writer. Wight is best known for his semi-autobiographical stories, often referred to collectively as All Creatures Great and Small, a title used in some editions and in film and television adaptations. Wight's books are only partially autobiographical. Many of the stories are only loosely based on real events or people, and thus can be considered primarily fiction. The Herriot books are often described as "animal stories" (Wight himself was known to refer to them as his "little cat-and-dog stories"), and given that they are about the life of a country veterinarian, animals certainly play a significant role in most of the stories.
