Word Origin and History for doppler


1871, in reference to Christian Doppler (1803-1853), Austrian scientist, who in 1842 explained the effect of relative motion on waves (originally to explain color changes in binary stars); proved by musicians performing on a moving train. Doppler shift is the change of frequency resulting from the Doppler effect.
