Commemorative colloquium in honour of Karl-Heinz Rädler
Professor Rädler
Credit: AIP ArchivOn 23 June 2022, the staff of the Leibniz Institute for Astrophysics Potsdam (AIP) will commemorate the founding director of the institute and their colleague of many years, Professor Karl-Heinz Rädler, together with family, friends and scientific collaborators of the great researcher at a one-day colloquium. The event will celebrate Karl-Heinz Rädler's life's work in the field of magnetohydrodynamics and his significant contribution to the establishment of the institute as an internationally recognized research centre for astrophysics.
Karl-Heinz Rädler passed away on 9 February 2020 at the age of 84. From 1992 to 1998, he led the AIP as the scientific chairman. He was therefore the founding director in the difficult phase of the evaluation and conceptual reorganization of the institute, in which he played a central role. From 1992 to 2000, Karl-Heinz Rädler was also director of the Cosmic Magnetic Fields research area and the editor of Astronomical Notes.
Professor Keith Moffatt, an expert in the area of magnetic fields and long-time colleague of Karl-Heinz Rädler, who will deliver a tribute speech at the commemorative colloquium, had already recognized the outstanding importance of Rädler’s work in the early 1970s and predicted its great influence. He wrote recently in a publication: ”A dramatic change occurred with the realisation that magnetic field could grow on a much larger scale than the scale of the energy-containing eddies of the turbulence. This marked the birth of the ‘mean-field electrodynamics’ that has been so effective in describing dynamo action in large-scale systems in planetary physics and astrophysics.”
Throughout his life, Karl-Heinz Rädler was valued by his colleagues as a person and scientist of strong principles. Professor Klaus G. Strassmeier, director of the research branch Cosmic Magnetic Fields today, regrets: “The field of Astrophysics and the AIP have lost a great researcher of humility and integrity, who was particularly concerned about preserving and maintaining the 300-year history of astronomy in Berlin and Potsdam, which he also helped to shape.”
The AIP will celebrate Karl-Heinz Rädler's fundamental contributions both to the institute’s history and to magnetohydrodynamics and the decoding of magnetic fields with a one-day event. The colloquium will begin at 10 am with a series of scientific lectures and continue with a festive reception from 2 pm onwards.
