ANAL,YS‘I’, APKlL 1993, VOL. I18 41N Obituary Professor Dr. Wilhelm Simon Wilhelm Simon was born in 1929 in Switzerland, graduated in Chemistry at the Swiss Federal Institute of Technology in 19.53 and received his Ph.D. degree in 1956 at the Department of Organic Chemistry of the Swiss Federal Institute of Technol- ogy in Zurich (ETH). In 1961 and 196.5, respectively, he became ‘Privatdozent’ and ‘Assistenz-Professor’ for instrumental methods of analysis at the same school. He was promoted to ‘ausserordentlicher Professor’ in 1967 and since 1970 he was full professor in chemistry at ETH. During his early career his research interests included acid-base equilibria using glass electrodes, automation of elemental analysis of organic compounds, instrumentation in vapour pressure osmometry, Curie-Point pyrolysis instrumen- tation and pyrolysis-mass spectrometry.Since 1966, his research interests, however, were largely focused on studies of the ion selectivity of organic compounds and biological systems, the design of chemical sensors and their application in biology and medicine, as well as high resolution separation techniques. He wroteko-authored two books and about 440 papers/articles on these topics. During his career, 107 doctoral students received Ph.D. degrees at ETH from his group. He was Editor, member of the Editorial Board, or Advisory Editor of eight scientific journals and series on monographs, and was a member of The Royal Society of Chemistry, the American Chemical Society, the American Microchemical Society, the New York Academy of Sciences, the Chemical Society in Zurich, the Swiss Chemical Society, the Naturfor- schende Gesellschaft in Zurich, the Swiss Society of Chemical Industries (member of the board), the Association of Swiss Chemists (member of the board 1967-1981), the Swiss Society for Analytical and Applied Chemistry and the Swiss Society for Instrumental Analysis and Microchemistry .He received the Swiss Chemical Society Award, the Benedetti-Pichler Award of the American Metrochemical Society, the Fritz- Pregl-Medal of the Austrian Society for Analytical Chemistry and was an honorary member of the Hungarian Academy of Sciences, the Institute Grand Ducal, Luxemburg, and the Japan Society for Analytical Chemistry, as well as honorary doctor (horonis causa) of the Technical University in Budapest.He received the Talanta Medal in 1991. Professor Simon will be long remembered for his many scientific achievements, but particularly for his studies of ion transport and selectivity in ion-selective electrodes. His group have synthesized over 1000 synthetic carriers, and many are now used in commercial sensors, particularly in clinical analysis. He was a superb orator, and anyone who listened to any of his lectures at international conferences could only have been enriched by his clear and precise communication of his science. He enjoyed his life to the fullest, and was knowledge- able about many subjects outside of his scientific discipline. He is survived by his wife Agnes. Professor M . R. Smyth Dublin City University Chirality Medal Nominations are invited for the Chirality Medal to be awarded in 1993 at the 4th International Symposium on Chiral Discrimination in Montreal, Quebec, Canada. The Chirality Medal was instituted by the Italian Chemical Society in connection with the International Symposium on Chiral Discrimination in Rome in 1991. This Medal is awardcd to recognizc distinguished achievement in any aspect of the field of Chiral Discrimination. Nominations, together with a short supporting statement, should be sent before April 30, 1993, to: Professor A.F. Fell, Secretary, Chirality Medal Iionours Committee, Pharmaceutical Chemistry, University of Dradjord, Bradford, UK BD7 1DP.
