Biography
Kayser was born at Bingen am Rhein. Kayser's early work was concerned with the characteristics of acoustic waves. 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. In 1905, he wrote a paper on electron theory.
The kayser unit, associated with wavenumber, of the CGS system was named after him. He died at Bonn in 1940.
