Other literary forms
In addition to the many novels he published, A. J. Cronin wrote one play, Jupiter Laughs, which was produced in Glasgow and New York City in 1940. His autobiography, Adventures in Two Worlds (1952), remains the best account of his formative years as well as an engaging vehicle for many of his opinions. In 1926, he also wrote two medical studies, Report on First-Aid Conditions in British Coal Mines and Report on Dust Inhalation in Haematite Mines. His journeys to investigate the conditions on which he reported became the basis of the fictional accounts of mining communities found in The Stars Look Down and The Citadel.
