The first radiosonde was used in 1929. The Frenchman, Robert Bureau invented it.
A radiosonde(Sondeis French and German for probe) is a unit for use in things such as weather balloons that measures various atmospheric parameters and transmits them to a fixed receiver.

The radiosonde is attached helium or hydrogen- filled balloon, generally called a weather balloon, and the balloon lifts the radiosonde to altitudes exceeding 115,000 feet. During the radiosonde's ascent, it transmits data on temperature, pressure, and humidity to a sea-, air-, or land-based receiving station (According to google that is) XD ;)
