Caption: Edouard Branly (1844-1940), French physicist and inventor, in his laboratory. Born Eugene Edouard Desire Branly, he is most famous for his inventions in telegraphy, but first studied physics and then medicine, carrying out clinical experiments in medical physics. This led to the development of early radio or wireless telegraphy equipment. He began studies on this in 1890, and was honoured in 1900 for 'discovering the principle of wireless telegraphy'. Photograph published in 'La Telegraphie Sans Fil' (Wireless Telegraphy, 1914), by the French geophysicist Alphonse Berget (1860-1934).
