Denis Pellerin, dedicated photo historian, was a teacher for over 30 years and has been interested in photography since the age of ten. He was bitten by the stereo bug in the 1980s, has been fascinated by the Diableries for over 25 years, and has written several books and articles on 19th-century stereo photography for various magazines, institutions and museums. He graduated with an MA in Art History at the Sorbonne in 1999 and has since been specializing in French and British Victorian genre stereo views.
