The News Baron Marcel Nicolet (1912-1996) PAGES 267, 270 Marcel Nicolet, honorary founder and di­ rector of the Institut d'Aeronomie Spatiale de Belgique, passed away on October 8,1996. Born in the village of Basse Bodeux, Belgium, on February 26,1912, Nicolet completed his studies in Greek and Latin Classics and went to the University of Liege to study philology. After a few months, he switched courses and regis­ tered as a student at the Faculty of Sciences, where he obtained a degree in physics in 1934 after writing a dissertation on the spectrum of 0 and B stars. He published this work with Paul Swings in the Astrophysical Journal. Marcel Nicolet (left) with Senator Lyndon Nicolet was soon noticed by Jules Jaumotte, B.
