Félix-Jacques Moulin was a French photographer during the 1850s and 1860s, and was a character in the latest novel we read, Paris Red. His work was largely based around taking pictures of young girls, most often in the nude. In 1851, all of his works up until that point were confiscated, and Moulin was sentenced to prison for the nature of his works. 
Many of them still do not have titles for this reason, as court records state that they were “so obscene that even to pronounce the titles (…) would violate public morality.” This is the case with the photograph pictured.
After his release, Moulin continued his work, although this time more privately. In addition, he sold photography equipment and taught lessons on the craft. In 1856, Moulin was funded by the French government to take a photographic trip to Alegeria, where he returned with almost 1900 images of landscapes, cities, archeologic surveys and portraits of inhabitants, despite his challenges with humidity, quality of water, and working out in the open. Three hundred of these images were published when he returned home.
