Scope and Contents

From the Collection: The collection contains correspondence, manuscripts and typescripts, printed material, and photographs, drawings, and slides, 1901-1983, documenting the career and research of pediatrician Charles C. Chapple. The bulk of the collection concerns Chapple's work on congenital dislocation of the hip in infants; fetal abnormalities and developmental defects; and the development of the Chapple Incubator and Isolette.

Series 1 contains miscellaneous correspondence and printed material concerning Chapple's life and career, including copies of his curriculum vitae and bibliographies and miscellaneous typescript chapters of professional reminiscences, containing his views on abortion, his inventions, and aspects of his career.

Documentation of several of Chapple's research projects and developments is contained in Series 2. The bulk of the series concerns congenital dislocation of the hip, including correspondence with Sir Denis Browne, and the Chapple Incubator and Isolette. The incubation material includes correspondence; a printed brochure; a patent; notes on intended modifications; material assembled by Charles C. Chapple on the history of pediatric incubation; a rough transcript of an oral interview with Chapple about the history of the Isolette; and a substantial collection of newsclippings and printed material with many items showing Isolettes in use. The series also contains miscellaneous files on some of Chapple's other projects, including three folders of typescript, labelled "Random memos", documenting discussions, experiments, personal reflections, and published references, December 1948 through March 1950, on hormones and other possible topics of research.

Printed advertisements used as promotional materials for Chapple devices, including the Incubator, Isolette, Croupette, and Electric Ear Lamp, 1937-1972, are in Series 3.

Typescripts and drafts of some of Chapple's speeches and presentations, 1937-1973, are in Series 4, while typescripts and drafts of several of his published and unpublished works, 1953-1972, are in Series 5. Many of these items concern congenital deformities, fetal developmental defects, and infant incubation.

An extensive collection of visual material concerning Chapple's work, 1931-1970, is preserved in Series 6. Series 6.1 contains drawings and paintings by Chapple, including a 1935 diagram of the Chapple Incubator and a 1938 design of the chair bed devised for congenital hip dislocation patients. Series 6.2 contains photographs of Chapplejinventions, including the Incubator, Isolette, a helium chamber, and an exerciser for feet and legs, and photographs of congenital hip dislocation patients, including x rays showing the hip dislocation of Chapple's daughter, Cornelia. Sets of photographic slides used in presentations on infant incubation, developmental defects, and the interaction of aluminum and mercury, are in Series 6.3. Series 6.4 contains glass lantern slides, primarily images of congenital hip dislocation patients at Philadelphia area hospitals, 1931-1954. Many of these slides include clinical information on the patient and case. There are also lantern slides on infant incubation and developmental deformities. Although the distinctions between the several sets of slides in Series 6.3 and 6.4 is often unclear, these original distinctions have been maintained.
