We are mourning our Professor Dr. Klaus Banert, who died suddenly and unexpectedly on September 19, 2020. We are deeply affected and our thoughts are with his family. We wish his family a lot of strength and all the best.

Prof. Dr. Klaus Banert †

Klaus Banert was born in Wattenscheid, Germany, in 1955. He studied chemistry at the Ruhr-Universität, Bochum, and received his doctoral degree in 1982, working under the direction of Prof. W. Kirmse in the field of rearrangement reactions of carbenium ions. In 1983 he went to the University of Siegen to obtain his habilitation on rearrangement reactions of organic azides in 1990. He received calls to the Universities of Cologne and Chemnitz in 1993 and became full professor at the University of Chemnitz since this time.
