Julian Mandel was the pseudonym of Lucien Waléry, a well known photographer of the same period. It can be confusing that there were two other photographers using the name Walery as well: Count Stanislaw Julian Ostrorog (1830-1890 and his son son Stanislaw Julian Ignacy, Count Ostrorog (1863-1935).
Lucien Waléry stands out in the night lights of Paris because he photographed an extraordinary number of beautiful women from most of the particular risque dance revues from the early 1900’s through the 1920’s.
His photos were republished through photo studios like Pc Studio and Alfred Noyer Studio. Walery photographed his models in studio, with lace and nice props as well as pure nudes in nature going outdoors. Mandel was a member of, and participated in, the German avant-garde “new age outdoor” or “plein air” movement.
Walery also created “plein-air” and exquisite deco-style nudes in the 1920s. He photographed the notorious Mata Hari
and Josephine Baker. It may well be that Walery used the name “Mandel” when selling work to publisher Alfred Noyer, for publishing as postcard-sized images.
