Abstract:
This, then, is what it has been all about. Today I mark the end of an academic career that ranged over 45 years. 1952 was the starting point. In that year, as a medical student, I was accepted as a research assistent by Prof. G.G.J. Rademaker, a neurophysiologist and at the time head of the Department of Neurology at the Academic Hospital in Leiden. The neurological research period was followed by a mycological one. Having received my MD degree and doing my military service, I was asked to carry out a study into the prevalence, prevention and treatment of mycological infections in military personel. For this reason I worked for more than 1, 5 years in Baarn at the section Medical Mycology of the Phytopathological Laboratory, an interacademic institution of the Universities of Amsterdam and Utrecht (1956-1958). Immediately after the military service I became a resident in psychiatry and started - together with the biochemist Prof. B. Leijnse - a research program into the biological determinants of depression. The period of psychiatric investigation lasted until this very day, albeit in different locations, i.e. Rotterdam, Groningen, Utrecht, New York and Maastricht respectively.
