!!!Doppler, Christian

b. Salzburg, Nov. 29, 1803, 
d. Venice (Italy), March 17, 1853, important mathematician and 
physicist; father of Adolf  Doppler. After teaching in Prague, 
Chemnitz and Vienna, became professor of experimental physics in 
Vienna (1850), founded the Institute of Physics at the University of 
Vienna. Discovered the D. effect (named after him) in acoustics and 
optics (the influence of motion on a source of light or sound and its 
observer, e.g., the apparent deepening of a passing train's whistle), 
which he described in his most significant publication "On the 
coloured light of double stars and other constellations in the 
heavens" (1842); this paved the way for the measurement of the radial 
velocity of stars.
