A.J. Cronin

A.J. Cronin was a Scottish author of nonfiction, literature and fiction novels. He is famously known for his novel The Citadel published in 1937. The book tells a story of a doctor of welsh origins who quickly climbs the ladder of success in London. Cronin closely included this scene as a Medical Inspector of Mines and later working as a doctor in Harley Street. The novel promoted what was then regarded as controversial new ideas related to medical ethics and also inspired the formation of National Health Service.
