The foundation and early meetings of the Society for Pediatric Radiology

Among the sources for this article were interviews of Drs. Frederic Silverman, John Gwinn, the late John Kirkpatrick, and Bertram Girdany. Much information was obtained from the archives of the Society for Pediatric Radiology. The writer is grateful for the privilege of consulting a draft of an unpublished history of the society by Dr. Gwinn. Dr. David Baker kindly reviewed a semifinal version of the article. Additions and corrections by others who were actually present at these events will be welcome.
