These images are from a collection of loose photographs and memorabilia, kept in a cardboard box by my grandfather, Joseph Cahalan, MD.  Notable among them are several images of John C. Cahalan, Sr.

​

Numbered in the order in which they were scanned--a indicates the face, or obverse, of the photo, and b indicates its reverse (if information was to be found there)--this group includes several photographs which have been identified; that information is included in the captions to the images. The originals were first grouped and scanned on January 6th, 2007, and are filed under that date. They have been re-scanned at a higher definition for this upload.
