Heinrich Gustav Johannes Kayser (membre de la Royal Society)[1] (en allemand : [ˈkaɪzɐ], né le 16 mars 1853 et mort le 14 octobre 1940, est un physicien et un spectroscopiste allemand[2],[3].

Biographie

Kayser est né à Bingen am Rhein. Les premiers travaux de Kayser portent sur les caractéristiques de l'onde acoustique[4]. Il découvre la présence d'hélium dans l'atmosphère terrestre en 1868 pendant une éclipse solaire lorsqu'il a détecté une nouvelle ligne spectrale dans le spectre solaire. En 1881, Kayser invente le mot "adsorption". Avec Carl Runge, il a examiné les spectres des éléments chimiques[5],[6],[7]. En 1905, il écrit un article sur la théorie des électrons.

L'unité kayser, associée au nombre d'onde, du système d'unités Centimètre gramme seconde porte son nom. Il est mort à Bonn en 1940.
