The discovery of the radioconduction is a phenomenon which revolutionized the means of communication. It is at the origin of the development of the TSF (Télégraphie Sans Fil, or wireless telegraphy). As a member of the French Academy of Sciences (it gains vis-a-vis Marie Curie), Branly received international recognition. No more than about fifteen years separate the first wireless transmission across a few meters (1890) from the first transatlantic communication (Marconi, December 1901).

Antoine-Laurent Lavoisier studied at the Académie des Sciences de l'Institut de France (then "Collège Mazarin") from 1754 to 1761. He was elected to the Royal Academy of Sciences in 1768, where he presented his important studies on oxygen in chemistry. These began with a "pli cacheté" of Nov. 2, 1772, and, after he experimentally proved the chemical composition of water by the quantitative method, culminated in his abandoning of the phlogistic theory in 1785.
