James R. Norris, currently Emeritus Millikan Professor of Chemistry at the University of Chicago, is a well-known electron paramagnetic resonance (EPR) spectroscopist. He obtained a Bachelor of Science at the University of North Carolina in 1963 and his Ph.D. in physical chemistry at Washington University, St. Louis in 1968. He spent the next 27 years at Argonne National Laboratory reaching the rank of Senior Chemist and the Section Head of Electron Transfer and Photosynthesis. He joined the University of Chicago as full Professor in 1984 where he served as Chairman of Chemistry for six years beginning 1997. In 2003 he received the distinction of becoming the Robert A Millikan Distinguished Service Professor of chemistry. Stefan Weber has studied chemistry at the University of Stuttgart and received his Ph.D. degree in Physical Chemistry at the University of Stuttgart. Thereafter, he spent 2 years as a postdoctoral researcher (Alexander-von-Humboldt-Fellowship) with Prof. Norris at the Department of Chemistry, University of Chicago. His habilitation in Experimental Physics was received from the Free University of Berlin. Since 2008 he is a full Professor of Physical Chemistry at the University of Freiburg, Germany. In 2010 he was elected Morino Lecturer 2010 of the Morino Foundation Japan.
