Son of a mechanic, Oswald-Pierre Heidbrinck, wishing to devote himself to painting, he would have been a resident in his youth at the art school of the City of Bordeaux after winning a competition. In 1882 he received a pension which allowed him to study in Paris.
He was a student of Jean-Léon Gérôme, Jules Lefebvre and Gustave Boulanger. In 1885, he exhibited a portrait at the Salon des artistes français. In 1892 and then in 1899, he exhibited at the National Salon of Fine Arts: that year ten drawings and six engravings (etchings and lithographs) including a self-portrait. In the meantime, he began to actively collaborate on various illustrated periodicals such as Le Chat noir, Le Courrier français, Le Rire...
He was close to Jacques Villon and Henri de Toulouse-Lautrec, as a “chronicler-drawer of Montmartre life”, an attentive witness to all the players in the field. He worked for master glassmakers and illustrated some high-end works.
