Heinrich Gustav Johannes Kayser ForMemRS [1] (German: [ˈkaɪzɐ]; 16 March 1853 – 14 October 1940) was a German physicist and spectroscopist. [2]
Kayser was born at Bingen am Rhein. Kayser's early work was concerned with the characteristics of acoustic waves. [3] He discovered the occurrence of helium in the Earth's atmosphere in 1868 during a solar eclipse when he detected a new spectral line in the solar spectrum. In 1881, Kayser coined the word “ adsorption”. Together with Carl Runge, he examined the spectra of chemical elements. [4] [5] [6] In 1905, he wrote a paper on electron theory. [7]
The kayser unit, associated with wavenumber, of the CGS system was named after him. He died at Bonn in 1940.
