What Is the Doppler Effect?
1. Christian Doppler
The Doppler effect is named after Christian Andrea Doppler, the physicist who first described the phenomenon. Doppler was born in Salzburg, Austria, in 1803, and died in 1853. It was in 1842 that he presented his groundbreaking work when he was aged 38 years old. At the same time, a French physicist by the name of Armand Hippolyte Louis Fizeau was also making discoveries on the phenomenon. Fizeaus work was able to help Doppler make his own work more accurate. In France, the phenomenon is known as the Doppler-Fizeau effect. Their discoveries are now a key component of many scientific branches and, in 2017, a Google Doodle celebrated Dopplers 214th birthday.
