Rolf Gleiter is Professor for Organic Chemistry at the Heidelberg University. He received his Ph.D. in 1964 in the field of Organic Chemistry at the University of Stuttgart with F. Effenberger. Postdoctoral work was carried out with P. von R. Schleyer at Princeton University (1965/66) and Roald Hoffmann at Cornell University (1966 - 1968). From 1969 -1972 he did his habilitation at the University of Basel in the laboratory of E. Heilbronner. From 1973 - 1979 he served as Full Professor at the Technical University of Darmstadt followed by a chair of Organic Chemistry at Heidelberg University since 1979. His fields of interest are Physical Organic Chemistry - photoelectron spectroscopy, applied quantum chemistry - and the chemistry of alkynes, strained hydrocarbons and metallic pi-complexes. He has authored and co-authored more than 650 papers, including reviews, and edited a book on "Modern Cyclophane Chemistry" with Wiley-VCH.

Gebhard Haberhauer is Professor for Organic Chemistry at the University of Duisburg-Essen. He studied chemistry at the Universities of Vienna and Heidelberg. He received his Ph.D. from the University of Heidelberg under the supervision of Rolf Gleiter. He spent as postdoctoral fellow one year in the laboratory of J. Rebek, Jr, at the Scripps Research Institute in La Jolla. After working one year at the BASF in Ludwigshafen, he returned to the University of Heidelberg, where he did his habilitation (2001 - 2005). In 2005, he was appointed Professor for Organic Chemistry at the University of Duisburg-Essen. His current research interests include chirality transfer and induction in molecular recognition and molecular devices.photoelectron spectroscopy, applied quantum chemistry - and the chemistry of alkynes, strained hydrocarbons and metallic pi-complexes. He has authored and co-authored more than 650 papers, including reviews, and edited a book on "Modern Cyclophane Chemistry" with Wiley-VCH.
