Professor Doppler over several weeks has excited me with his ideas, the one more brilliant than the other. I must think about them day and night.--Bernhard Bolzano, 1844
Mr Doppler has already demonstrated his very promising abilities to the scientific community through his numerous published works in mathematics and physics. The expectations raised by his hitherto published works would multiply when one enters into personal acquaintance with him. You are not only struck by how many highly interesting and fruitful ideas, in many areas of knowledge, that so young a scientist is able to produce, but you also convince yourself with the greatest pleasure that this exceptional spiritual power combines with an amiable character, genuine unaffected determination and with that pure love of science and truth ...

We offer the following four items, two papers by Doppler in support of his new theory; and another two papers by the great mathematician Bernhard Bolzano, one beinbg a very early review and supporting piece (1843) on Doppler's great paper of 1842; and a second Bolzano on the work of Doppler, in general, published in 1847.)
1) Christian Doppler. "Weitere Mittheilungen, meine Theorie des farbigen Lichtes der Doppelsterne betreffend" in Annalen der Physik und Chemie; Leipzig, Johann Ambrosius Barth, 1852, volume 85 (161), where the Doppler paper occupies pp. 371-378. This appeared slightly earlier in the year inSitzungsberichte der Kaiserlichen Akademie der Wissenschaft, volume 8 (Kaiserl. Akademie der Wissenschaften in Wien. Mathematisch-Naturwissenschaftliche Klasse), 1852. I reproduce Doppler's bibliography in the Kaiserl. document at teh end of this post--it may be interesting and useful.)
2) Doppler: Einige weitere Mittheilungen und Bemerkungen, meine Theorie des farbigen Lichtes der Doppelsterne etc betreffend. In Annalen der Physik, Volume 81, (#157), pp 270-275, 1850.
And these two contributions from the great mathematician Bernhard Bolzano (an early champion of the genius of Doppler):
3) Bolzano, Bernhard. Ein paar Bemerkungen ueber die neue Theorie in Herrn Professor Chr. Doppler's Schrift: Ueber das farbige Licht der Dopplesterne und einiger anderer GEstirne des Himmels. In the Annalen der Physik, 1843, volume 60 (vol 136) p 83-88. (This appears in the Doppler bibliography below except under a somewhat different and abbreviated title.) (Bolzano bibliography/collected works as 1843b.) (This is a very enthusiastic and, well, very supportive review of the young Doppler's work--Bolzano was one of the people very early on the scene to appreciate Doppler's genius (this beginning around 1837).)
4) Bolzano: "Christ. Doppler's neueste Leistungen auf dem Gebiete der physikalischen Apparatenlehre, Akustik, Optik und optischen Astronomie”, Annalen der Physik, 72: 530–555 (Bolzano bibliography/collected works as 1847c.) (A review and appreciation of Doppler's work.)

.From the Dictionary of Scientific Biography:
"Doppler’s scientific fame rests on his enunciation of the Doppler principle, which relates the observed frequency of a wave to the motion of the source or the observer relative to the medium in which the wave is propagated. This appears in his article "Ueber das farbige Licht der Doppelsterne und einiger anderer Gestirne des Himmels" (read 25 May 1842). The correct elementary formula is derived for motion of source or of observer along the line between them; the extension to the motion of both at the same time appears in an article of 1846. Doppler mentions the application of this result both to acoustics and to optics, particularly to the colored appearance of double stars and to the fluctuations of variable stars and novae."(DSB).
