Professor Klaus Unger, formerly University of Mainz, Germany, and Merck KGaA, Darmstadt, Germany, passed away on October 7, 2020.
Professor Unger was a distinguished researcher in the field of porous materials and high-performance liquid chromatography (HPLC). His research interests included the design and synthesis of porous materials as adsorbents and catalysts, their surface functionalization and characterization, the development of liquid-phase separation methods, and multidimensional liquid chromatography in proteomics.
Klaus Unger studied chemistry at the Technical University of Darmstadt, Germany, where he received his Ph.D. under the supervision of Hans Wolfgang Kohlschütter in 1965. He finished his habilitation in Darmstadt in 1969 and was appointed Assistant Professor of Chemistry there. From 1977 to 2001, he was Professor of Chemistry at the University of Mainz, Germany. After his retirement, he worked at Merck KGaA, Darmstadt, Germany, as Senior Researcher in the field of bioseparation from 2001 to 2009.
Among many other honors, Professor Unger received the Pregl Medal from the Austrian Society for Analytical Chemistry in 1991, the A. J. P. Martin Award from the Royal Chromatography Society, London, in 1993, the American Chemical Society (ACS) Award for Chromatography in 1995, the Clemens Winkler Medal from the Division of Analytical Chemistry of the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society) in 2007, the CASSS Annual Scientific Achievement Award from the California Separation Science Society in 2010, and the Nernst–Tswett Award from the European Society for Separation Science in 2016.
