    Critical to the success of Marconi's pioneering work on radio telegraphy was the device needed to detect the radio telegraph messages on reception. Marconi finally settled on the "coherer." The invention of the device is often attributed to Oliver Lodge, a British physicist of the late 19th century. The detection properties of this device were, in fact, discovered by Edouard Branly, a French exper... View full abstract»
