1962 SALIL CHATTERJEE
The utilization of ridgeology for personal identification incorporates many areas of the physical sciences including the lesser-known sciences of edgeoscopy and poroscopy. Edgeoscopy is a science that was pioneered in 1962 by Salil Chatterjee of India. Chatterjee created edgeoscopy while researching the possibility of a new criminal identification method. Edgeoscopy is a method that examines details, or characteristics, found along the ridge edge:
“These characteristics are the result of the alignment and shape of the individual ridge units as well as the pores close to the edge of the ridge. However, these shapes are only of use when the friction ridges are clearly reproduced in both the latent and the exemplar prints.” Kuhn, Kurt E. “The Fingerprint Science and Ridgeology.”
