It is suggested that Breit and Tuve's 1925 application of pulses to ionospheric sounding, which led to the most widely used form of radar, also gave rise to a scientific instrument whose utility, flexibility, and general suitability for intended applications place it on a par with such familiar and standard devices as the telescope or spectrograph. By way of background, there is included a discussion of the circumstances attendant upon the first measurement of ionospheric layer height, which took place in 1912.
