Monsieur Ribeaux was a balding, bespectacled Frenchman who was the curator of a museum which housed the L'Etoile de Joie diamond. With a small computer device, Ribeaux engaged an electric eye-beam perimeter around the pedestal on which the diamond rested. He was terribly upset to find it gone after two jewel thieves, Max and Quincy, shut off the elecric eye-beams and stole it. But after Jim Douglas and mechanic Wheely Applegate, the operators of Herbie, recovered the diamond, Ribeaux rewarded the little car with a kiss, which made Herbie blush.
Monsieur Ribeaux was played by actor Francois Lalande.
