I was born on June 3rd, 1929, in Graenichen in the Canton of Aargau, Switzerland, where I went to the public schools until the age of 16.
From 1949 to 1953, I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. It is in the last year of this study that I made my first contacts with fundamental research, when working on the isolation and characterization of a new isomer of Cl34 with a half-life of 1.5 seconds.
On the recommendation of my professor in experimental physics, Paul Scherrer, I took an assistantship for electron microscopy at the Biophysics Laboratory at the University of Geneva in November 1953. This laboratory was animated by Eduard Kellenberger, and it had two prototype electron microscopes requiring much attention.
In the 1950s, the Biophysics Laboratory at the University of Geneva was lucky enough to receive each summer for several months the visit of Jean Weigle. He was the former professor of experimental physics at the University of Geneva.
