Édouard Branly — Physicist and physician, inventor of the coherer, 1844–1940
A physicist and physician, professor at the Institut catholique de Paris, he devised in 1890 a filings tube able to detect Hertzian waves. He took out no patent on it. His state funeral, six months after the declaration of war, was held at Notre-Dame in the president of the Republic’s presence. (Editorial synthesis)
