French engineer and inventor of the principle of stepper motor in 1936.
His work focuses on electromagnetic mechanism domain applied to electric clocks devices. Marius Lavet is responsible, among other things, to the introduction of the transistor in 1952 to replace electronic switching contacts on clock devices with pendulum and self-sustaining balance spring. He also designed many micromotors, one of them, was a stepper motor (1936) nowadays applied on needle quartz watches (analog). Marius Lavet donate some parts of his properties to a foundation established under the aegis of the Fondation de France, to provide the award-Lavet Chéreau. This award supports the major role of the engineer-inventor in French economic development. The Association Marius Lavet organizes the Award Lavet Chéreau. The Marius Lavet Award was assigned for the first time in 2001.
