Achille Essebac (January 29, 1868 – August 1, 1936) was a French writer primarily known for his novel Dédé about an ill-fated homoerotic friendship between two schoolboys. Essebac was a pseudonym, since his original surname Bécasse is a derogatory word for goose. Essebac was also a photographer of young men, preferably clothed in Renaissance or medieval theatrical costumes. A recently rediscovered album with 156 photographs by him was sold for €3,500 in Paris.
