About Maurice Yves Sandoz from the museum's site:
Sensitive and generous, when he learned that the city of Le Locle wanted to create a museum to house its watch and clock collections at the Château des Monts, he donated an important part of his personal collection of automatons to his commune of origin. Along with his friends, the Professor Alfred Chapuis and Mr. Fred Cornaz, poet and amateur decorator, he designed the layout of the room that since that time bears his name. Not only did Maurice Sandoz possess admirable collections of watches, jewelry and automatons, he also wrote literary works in French, English, German, Italian and Portuguese. Remarkably multi-lingual, he was a man of many talents who held Doctor's degrees in both Letters and Sciences.
