23 Facts About Klaus Hasselmann
1.
2.
Klaus Hasselmann was awarded the 2021 Nobel Prize in Physics jointly with Syukuro Manabe and Giorgio Parisi.
3.
Klaus Hasselmann spent five years in the United States as a professor at the Scripps Institution of Oceanography and the Woods Hole Oceanographic Institution, and a year as a visiting professor at the University of Cambridge.
4.
Klaus Hasselmann is best known for developing the Hasselmann model of climate variability, where a system with a long memory integrates stochastic forcing, thereby transforming a white-noise signal into a red-noise one, thus explaining the ubiquitous red-noise signals seen in the climate.
5.
Klaus Hasselmann's father Erwin Hasselmann was an economist, journalist, and publisher, who was politically active for the Social Democratic Party of Germany from the 1920s.
6.
Klaus Hasselmann attended Elementary and Grammar School in Welwyn Garden City, and passed his A-levels in 1949.
7.
Klaus Hasselmann has said that "I felt very happy in England" and that English is his first language.
8.
Klaus Hasselmann's parents returned to Hamburg in 1948, but Klaus remained in England to finish his A-levels.
9.
Klaus Hasselmann has been married to the mathematician Susanne Hasselmann since 1957 and they have worked closely professionally; his wife was a senior scientist at the Max Planck Institute for Meteorology.
10.
Klaus Hasselmann graduated in physics and mathematics at the University of Hamburg in 1955 with a thesis on isotropic turbulence.
11.

17.
Klaus Hasselmann has published papers on climate dynamics, stochastic processes, ocean waves, remote sensing, and integrated assessment studies.
18.
Klaus Hasselmann later discovered plasma physicists were applying similar techniques to plasma waves, and that he had rediscovered some results of Rudolf Peierls explaining the diffusion of heat in solids by non-linear phonon interactions.
19.
Klaus Hasselmann later suggested how to extract 'fingerprints' of anthropogenic climate change.
