Karl-Heinz Rädler

His research focused on cosmic magnetic fields. In the 1970s he explained how they were created in stars and planets using the dynamo model. He worked on the theory behind experiments with liquid sodium, which provided evidence for the cosmic dynamo.^[2]

He was the founding director of the Leibniz Institute for Astrophysics Potsdam, and he was its Scientific Chairman in 1992–1998, as well as leading its Cosmic Magnetic Fields group in 1992–2000. He was a professor at the University of Potsdam in 1994–2000. He was on the first senate of the re-founded Viadrina European University.^[2][3]
