This is an extention of Doppler's epochal “Ueber das farbige Licht der Doppelsterne und einiger anderer Gestirne des Himmels,” which appeared in Abhandlungen der Konigl. Böhmischen Gesellschaft derWissenschaften, (5th ser., 2 (1842), 465, and which was also published separately in Prague in the same year, (1842) in which the idea of motion is expressed to both source and observer, based on the experimental work of Buys-Ballot. “ The Doppler Theory/Doppler shift is of monumental applicability and importance, providing the foundation for sonar and radar, as well as for the general acceptance of the cosmological theory of the Big Bang (showing how the shift in the spectra of astronomical entities allows for the measurement of the rate of recession relative to the Earth.
“Buys-Ballot [Buys-Ballot, Christophorus Henricus Didericus (1817-1890)] also conducted one of the most famous experiments to confirm the Doppler shift. He put a group of musicians on a train and took up his position on a station platform. He asked the train driver to rush past him as fast as he could while the musicians played and held a constant note, and was able to detect the Doppler shift (as a change in pitch) as the train passed him (Filkin and Hawking 1997, p. 65).” --Eric Weisstein's Science Biography pages on the Wolfram Research website
“In 1845, Christophe Ballot, a Dutch meteorologist, conducted a public demonstration to prove it. Ballot lived beside a train line, and he noticed the change in pitch in whistles and sounds as the train passed him by. He pulled a few strings and got a train to pull along an open-air cart filled with trumpet players. Meanwhile, more trumpet players stood in a station. Ballot checked the pitch of their instruments, and then got each section to play the same note as the train hurtled — at an astonishing forty miles per hour — past the station. Although the players in the station stayed right on the note, the players in the train by seemed to be pitched a little too high, and dropped a little too low as the train passed the station. Everyone in the station could hear the changing notes as the trained passed, and one of the most useful tools in all of physics was finally recognized.” Esther Inglis-Arkell, Gizmodo (2013)
“In 1846 Doppler published a revised version of his principle where he considered both the motion of the source and the motion of the observer. Later, a French physicist, Armand Hippolyte Louis Fizeau (1818–1896), who made one of the first measurements of the velocity of light, generalized Doppler’s work by applying his theory not only to sound but also to light.”-- A. Roguin, "Christian Doppler, the Man Behind the Effect". The British Journal of Radiology, 75 (2002), 615–619

This volume also contains significant paper by Michael Faraday, the first German edition of "Thoughts on Ray Vibration", which suggests that no ether or other vibrating material is responsible for the transmission of light.
