"Werner Heinrich Gustav Kolhörster (28 December 1887 – 5 August 1946) was a German physicist and a pioneer of research into cosmic rays.
Kolhörster was born in ...
Schwiebus (Świebodzin), Brandenburg Province of Prussia. While attending the University of Halle, he studied physics under Friedrich Ernst Dorn.
Repeating the cosmic ray experiments of Victor Hess, in 1913-14 Kolhörster ascended by balloon to an altitude of 9 km, where he confirmed Hess´ result that the ionization rate from cosmic rays was greater at that altitude than at sea level. This was evidence that the source for these ionizing rays came from above the Earth´s atmosphere." - (en.wikipedia.org 12.01.2020)
