This instrument made it possible to establish the position of planes without having to see them, using only the sound they produced. The precision of the instrument was such, that it was used during the first World War by the French military, to repel night attacks from German bombers by pointing searchlights at them. This furthermore represented a rare technological superiority for the French. After this remarkable start in the fields of acoustics, he nonetheless decided to abandon this field. The reason being that his professor's own instrument didn't get chosen by the French military, and Rene feared he would have no academic future in this field. He then turned chronometry. He initially worked at the observatories of Nice (1910–1924) and Marseille (1924–1930), while already teaching at the "Ecole d'Ingenieurs de Marseille", before taking a chair as professor at the University of Besancon and becoming director of the Besancon observatory until 1957. During this time he oversees the installation of special clock, in a specially built room 5 meter underneath the observatories' library to maintain constant temperature, allowing the observatory to Join the establishment of a global time network. He is a founding member of the French society of chronometry, and its first chief of staff, creating in 1931 the journal "Annales Francaises de Chronometrie". In order to join the global mapping project "Carte du Ciel" (directed by his brother), he oversees the installation of a specific instrument: "astrographe triple" dedicated to this purpose." – Wikipedia.
