Born in July 1947 (vintage year for ufology!). Graduate in chemistry in 1970 (Université Libre de Bruxelles – Belgium), he has a PhD in History of Sciences and Technics (Université Charles de Gaulle-Lille III – France) since 1995.
Teacher of chemistry at the Athénée Provincial de La Louvière (Hainaut – Belgium) since 1970 and professor at the University of Mons-Hainaut (Lectures on history of experimental sciences) since 1996.
In 1972, he took a hand in the creation of the Société Belge d’Étude des Phénomènes Spatiaux (SOBEPS) and since 1976, he is the President of this society, chiefly involved in the edition of the periodical publication Inforespace.
In 1975, he has directed the edition of the collective book Des soucoupes volantes aux OVNI (From Flying Saucers to UFOs), and in 1977, he wrote a book upon old UFO sightings, La chronique des OVNI (The UFO’s Chronicle), edited by J.-P. Delarge, Paris. At the end of 1991, he has directed (and written some parts of) the first report on the Belgian UFO wave of 1989-91: Vague d´OVNI sur la Belgique. In the beginning of 1994, the second report was published (Vague d´OVNI sur la Belgique. 2. Une énigme non résolue). This second volume was prefaced by Isabelle Stengers, a well known philosopher and historian of science.
Actually, he claims to be somewhat eclectic and, besides ufology and history of science, he takes an interest in several other fields. So, he has published a critical study on the reforms introduced in the education: L´école et ses dupes (School and its Dupes), éditions Labor, 1996, collection Education 2000.
He is a corresponding member of the Comité National de Logique, d’Histoire et de Philosophie des Sciences (within the framework of the Académie Royale des Sciences, des Lettres et des Beaux-Arts de Belgique).
Here are his main publications as historian of sciences: La chimie de Nicolas Lemery, Brepols, Turnhout, collection De Diversis Artibus, tome 40 (N.S. 3), 1999. Scientific Editor of Alchemy, Chemistry and Pharmacy, volume XVIII des Proceedings of the XXth International Congress of History of Science (Liège, July 1997), Brepols, Turnhout, collection De Diversis Artibus, 2002.
