Born May 28, 1894, in a town that would not take the name Bellerive until 9 years later. Orphaned from his mother at the age of 6, he was raised by his father, who held the position of race guard at the Vichy racetrack. At a very young age he showed predispositions for drawing and entered as a typographer draftsman at the Mont-Louis printing house in Clermont-Ferrand. It was then that the First World War broke out. Mobilized in 14, Paul Devaux was wounded at Verdun and hospitalized in Dijon where he killed time with a penknife in the woods.
In 1922, he will have his work cut out for him by founding the Primo advertising agency, which will collaborate with the local economic fabric (Au Bon Marché, the Sornin Gallery, Treyve frères, Moinet…) and particularly with the Vichy Tourist Board, which will regularly call on him to promote the city. The following year, we find him at the newspaper le Petit Bourbonnais that he contributes to launch by his talent as an illustrator. This talent, he will put it, throughout his artistic career, at the service of many writers: Charles Maurras, Valery Larbaud, Maurice Constantin-Weyer, André Chamson and André Gervais with whom he will form a deep friendship.
