He graduated from the University of Lausanne in 1970 (Bachelor of Science in physics) and the University of Geneva in 1975 (Master of Science in astrophysics). He also graduated as a Swiss Air Force pilot in 1966, an airline pilot in 1974 and a test pilot in 1988. He was a member of the first group of European Space Agency (ESA) astronauts selected in 1978.
