Christian Doppler
Christian Doppler (/'krɪstʃən 'dɒplər/; German: [ˈkrɪsti̯an ˈdɔplɐ]; 29 November 1803 – 17 March 1853) was an Austrian mathematician and physicist. He is celebrated for his principle — known as the Doppler effect — that the observed frequency of a wave depends on the relative speed of the source and the observer. He used this concept to explain the color of binary stars.
Etymology
The term "Doppler" is derived from Christian Doppler's last name, in honor of his significant contributions to the field of physics. The Doppler effect is named after him.
