Denis Pellerin is a photo-historian with a passion for stereo photography.

He has been researching and learning about the history of stereoscopy for over 45 years and has written or co-written more than a dozen books and authored nearly seventy articles on his pet subject, both in French and in English.

His latest book “L’Emp’reur, sa femme et le p’tit Prince: la famille impériale, la photographie et le stéréoscope” was released in May 2023, less than two years after his study on the first thiry years of the stereoscopic medium: “Stereoscopy: the Dawn of 3-D”.

Since 2012 Pellerin has been the head curator of Dr. Brian May’s extensive collection of stereo photographs, now a charity, and for the past five years, he has been co-curating the Brian May Archive of Stereoscopy with Rebecca Sharpe.

Since 2012 Denis has given over a hundred and forty Zoom and in-person 3-D talks on different aspects of Victorian stereo photography.
