Archibald Joseph Cronin (July 19, 1896–January 6, 1981) was a Scottish novelist, dramatist, and nonfiction writer who was one of the most renowned storytellers of the twentieth century. His best-known works are The Citadel and The Keys of the Kingdom, both of which were made into Oscar-nominated films. The Dr. Finlay character originated in Cronin's 1935 novella, Country Doctor, which led to further stories that were collected in Adventures of a Black Bag. These provided the basis for the long-running BBC television and radio series entitled Dr. Finlay's Casebook.
