Christian Andreas Doppler (/ˈdɒplər/; German: [ˈkʁɪstiaːn ˈdɔplɐ]; 29 November 1803 – 17 March 1853)[1] was an Austrian mathematician and physicist.

[2] After completing high school, Doppler studied philosophy in Salzburg and mathematics and physics at the University of Vienna and Imperial–Royal Polytechnic Institute (now TU Wien).

In 1829, he was chosen for an assistant position to Professor Adam Von Burg at the Polytechnic Institute of Vienna, where he continued his studies.

[6] Before departing for the United States, Doppler was offered a teaching position at a state-operated high school in Prague, which convinced him to stay in Europe.

[2] In 1842, at the age of 38, Doppler gave a lecture to the Royal Bohemian Society of Sciences and subsequently published Über das farbige Licht der Doppelsterne und einiger anderer Gestirne des Himmels ("On the coloured light of the binary stars and some other stars of the heavens").

[8] Doppler continued working as a professor at the Prague Polytechnic, publishing over 50 articles on mathematics, physics and astronomy, but in 1847 he left Prague for the professorship of mathematics, physics, and mechanics at the Academy of Mines and Forests (its successor is the University of Miskolc[9]) in Selmecbánya (then Kingdom of Hungary, now Banská Štiavnica Slovakia).

While there, Doppler, along with Franz Unger, influenced the development of young Gregor Mendel, the founding father of genetics, who was a student at the University of Vienna from 1851 to 1853.

[10] Doppler died on 17 March 1853 at age 49 from a pulmonary disease in Venice (at that time part of the Austrian Empire).
