John Henry O'Hara, the American author from Pottsville, Schuylkill County, Pennsylvania, was so engrossed by the coal-rich Anthracite Region that he wrote about it in his professional work and personal correspondence for most of his life. The history, geography, and society of the area, particularly within a thirty-mile radius of Pottsville, were put under a microscope throughout O'Hara’s career. John O'Hara’s Anthracite Region covers the exciting period from the 1880s to 1945 in the coal region of Pennsylvania. John Henry O'Hara investigated, studied, and recorded the most intimate aspects of the upper class of his Pennsylvania Protectorate from his first novel, Appointment in Samarra, onwards. From the Aristocrats’ escape to Eagles Mere, Sullivan County to the amusement parks such as Tumbling Run and Marlin Park in the Anthracite Region, O'Hara captured every detail of the upper class’s way of life. The social enclaves such as The Out Door Club, The Pottsville Club, and The Schuylkill Country Club did not escape O'Hara’s pen in such novels as Ten North Frederick and The Lockwood Concern. These places, the people, and their fashionable attire, automobiles, houses, and schools are all captured within this unique photographic layout of O'Hara’s work that wonderfully re-creates the history of this region.
