Incroyable Destin Hubert Reeves

As a child, Hubert Reeves loved looking at the stars in the Quebec summer sky. An excellent maths student, at 18 he decided to become an astronomer. After graduating, he became a university teacher and researcher at NASA. He then moved to Europe, where, after extensive research, he discovered how cosmic rays generated the atoms of lithium, beryllium and boron. In the 1970s, while on vacation in the south of France, he shared his knowledge of astronomy with other holidaymakers at nightfall: the career of "popular science" for which he was so well known had begun!
