Musée Edouard Branly
Encyclopedia
The Musée Edouard Branly is a museum dedicated to the work of radio
pioneer Edouard Branly
(1844-1940). It is located in the 6th arrondissement at the Institut Catholique de Paris-ISEP, 21, rue d'Assas
, Paris
, France
, and open by appointment only.
The museum contains the research laboratory and equipment used by Edouard Branly
, a physics professor at the Institut Catholique de Paris
and inventor of the first widely used radio
receiver
, the Branly coherer
circa 1884-1886. Its collection includes a number of early devices used in wireless experiments, such as electrolytic detectors, insulated tubes filled with metal filings, a Righi oscillator, generators, electromagnets, metallic blades mounted on glass, electrical contacts, and a column of six steel balls stacked in a glass cylinder.
Radio
Radio is the transmission of signals through free space by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space...

Receiver (radio)
A radio receiver converts signals from a radio antenna to a usable form. It uses electronic filters to separate a wanted radio frequency signal from all other signals, the electronic amplifier increases the level suitable for further processing, and finally recovers the desired information through...

Coherer
The coherer was a primitive form of radio signal detector used in the first radio receivers during the wireless telegraphy era at the beginning of the twentieth century. Invented around 1890 by French scientist Édouard Branly, it consisted of a tube or capsule containing two electrodes spaced a...
