Son-in-law of Éclair Camera's founder Charles Jourjon, he took over the company after Jourjon's death in 1938. Mathot surrounded himself with two new collaborators, Marcel Terrus for the laboratory division, and André Coutant for the camera division. In 1947, Éclair introduced the 35mm Caméflex [or Camérette]. The Caméflex was a reflex camera allowing through-the-lens viewing. It could film in 35mm or 16mm with little more than a change of the film magazine and the film aperture plate. The camera came in two parts: The body contained the mechanism and the lens turret. The magazines, containing either 35mm or 16mm film, were pre-loaded and could be changed in 2 seconds while the camera motor was still running, since the film loops and the back pressure-plate of the film gate were included in the magazine. The camera could, of course, be tripod mounted and it could be hand-held with the magazine being balanced on the shoulder.  Scientific or Technical Awards (Class III) 1949: For the design of the Éclair Camérette (as the Caméflex was known in the US).
