Biography

Geiss was born in 1926 in modern-day Poland, the son of farmers Hans Geiss and Irene Wilk. In 1955, he married Carmen Bach.

Geiss studied physics in Göttingen from 1947 to 1950. He published his doctoral thesis in 1953, titled Isotopenanalysen an „gewöhnlichem Blei“. He then conducted research on geochronology at the University of Bern and University of Chicago. From 1958 to 1959, Geiss was an associate professor at the University of Miami before returning to Bern, working there until 1991. From 1995 to 2002, he was co-director of the Institut international des sciences spatiales. In 2019, a bronze statue of Geiss was erected on the University of Bern campus by Horst Bohnet.[2]

Johannes Geiss died on 30 January 2020 at the age of 93.[3]

Awards and Honors
gollark: You get more total energy as temperature goes up, and it's concentrated at different wavelengths.
gollark: Ah, it looks like Planck's law is what the graph is showing.
gollark: > If you make the temperature higher, then the frequency increases. No, you keep ignoring me on this.> Thus meaning the amount of photons emited is related/proportional to the temperature increasing.Also no, the amount is a different thing.
gollark: Also wrong, objects emit multiple frequencies at once and the relationship is more complex than that.
gollark: The energy is a property of the photon similarly to frequency and stuff, the energy doesn't have frequency either, but can I just say that trying to brute-force your way to coherent-sounding wording is not a path to great understanding.
