Pierre Dubreuil (March 5, 1872 - January 9, 1944) was a French photographer, born in Lille, who spent his career in France and Belgium.
As a pioneer of modernist photography, Dubreuil embraced innovative techniques and ideas that were celebrated, criticized, and at times, overlooked.
Over the course of his career, which was interrupted by both World Wars, Dubreuil's work was shown at the Photo-Club de Paris, the Albright Gallery exhibition in Buffalo, New York, the Little Gallery of the Amateur Photography Magazine in London, and the Royal Photographic Society.
