This material, which documents John Ridlon's medical career, consists of medical case files, casebooks, articles and papers, correspondence, photographic materials, diplomas and ephemera, and medical illustrations, relating to Ridlon's research and writings on orthopedics. Case files - a large majority of them pediatric - include tubercular infection of the joints, scoliosis and other deformities, spondylitis (spinal arthritis), and limb or joint injuries. There are hundreds of medical illustrations in the form of photographs mounted on board, photographic prints of early X-rays, and printed illustrations on loose sheets that show patients, symptoms or deformities, and treatments such as surgery, braces and casts; many of them were used by Ridlon in his published works.
Among the bound volumes are six casebooks (1889-1892); four letterbooks (1873-1903); an autograph manuscript, "Some comments on the principles and practice of Hugh Owen Thomas" (undated); a scrapbook of figures and illustrations (undated); three volumes composed of reprint clippings and manuscript notes (undated); and a bound volume of 88 reprints (1888-1923). There are also many diplomas and certificates received by Ridlon from various educational institutions.
Correspondents include: R. Osgood, A. Steindler, P. D. Wilson, R. K. Ghormley, J. E. Goldthwait, A. B. Judson, R. W. Lovett, H. W. Orr, S. W. Mitchell, H. Cushing. In addition to discussing medical cases and research, letters also document Ridlon's involvement with two charitable institutions: the Home for Destitute Crippled Children (Chicago) and the Country Home for Convalescent Children.
Accompanying the professional papers is a set of 118 black-and-white photographs taken during Ridlon's service as a surgeon in the U.S. Army Medical Corps during World War I. The photos were taken by several photographers at a medico-military training camp in Plattsburgh, N.Y., around 1916. Ridlon reported on these experiences at a medical conference in 1917 and used a set of 67 glass lantern slides to illustrate the lecture, 49 of which survive in the collection; a reprint of this paper is also available in the collection.
In the same series there is a set of 30 glass plate negatives and still image nitrate film negatives; these materials are closed to use but contain duplicate or similar images found in the print photographs. Finally, there are several portraits of Ridlon, chiefly photographs taken in his office and examination room, taken in 1911. A glass plate negative with a bust portrait of Ridlon rounds out the photographic series.
The collection also contains several folders of ephemera, early professional diplomas and certificates, letters of recommendation for Ridlon's Chicago appointment in 1892, and his obituary.
