Physical description:

11 boxes

Scope and content:

Contains 118 black-and-white photographs of the first medical military training camp at Plattsburgh, N.Y., circa 1916. Camp scenes include cook stations, mules and wagons, a water truck, machine gun pits, headquarters tents, officers and privates, and scenes from drills and reviews of infantry and cavalry. Several photographs show Ridlon during litter drills. Most of the prints are captioned, with some names present on the backs.

Accompanying the photo prints is a set of 49 lantern slides bearing black-and-white positive images of scenes from the Plattsburgh medical camp, most if not all of which are duplicated in the photographic prints in this same series. The original slide set numbered 67 slides. Accompanying the slides is a lecture script presented by John Ridlon at a conference in 1917, describing the camp and the American preparedness for war with respect to military medicine. The lecture text is a photocopy from reprint #82 in the volume Collected Papers of Dr. John Ridlon, also found in this collection).

Also in this series are 30 glass plate negatives which, like the lantern slides, contain duplicate images found in the photographs folders.

A set of nitrate negatives originally in the collection was digitized and then deaccessioned in 2023. Those images are only available in digital format.

The series is rounded out by three postcards from the camp at Plattsburgh; a glass plate negative bearing a bust portrait of Ridlon; three photographic studio portraits of Ridlon; two photographs of him seated at a desk in his office, and two of him in his examination room, one of which is a duplicate. A wall calendar seen in one image shows 1911 as the probable year the clinic photographs were taken.
