IDRAC, Pierre (1885 - 1935)

French physicist and meteorologist.

The development of the radio and the relative miniaturization of transmitters enabled a decisive step to be taken in altitude measurements. In 1927, the Frenchmen Pierre Idrac and Robert Bureau received, on the ground, for the first time, a short-wave transmission coming from the stratosphere. In 1929, Pierre IDRAC invented the radiosonde. This device, transported to a high altitude by a balloon filled with hydrogen, measured the pressure and temperature of the air and simultaneously transmitted the two measurements by radio.
