Jean-Martin Folz is the son of medieval historian
Robert Folz. After graduating from the
Lycée privé Sainte-Geneviève, he entered the
École polytechnique in 1966 and went on to become a
Corps des mines engineer. Reputed to be as bon vivant in private as he was austere or even negligent in public, far removed from the mundane, he scarcely revealed his private life, confessing only to a few passions: wine, scuba diving and Baroque music. ==References==
