Jean-Charles Kraehn was born in Saint-Malo. After an education in industrial graphics at the École Estienne, he took evening drawing courses at the Ville de Paris. He published his first illustrations in Scouts de France in 1980-1981 and subsequently contributed to several publications of Hachette and to history books by I.D. Program. He began his comics career in 1984 with the historical adventure series 'Les Aigles Décapitées' for the publishing house Glénat. Initially, the scripts were written by Patrice Pellerin, but later on Kraehn took over himself, leaving the artwork to Michel Pierret shortly afterwards. Kraehn left the series completely in 1999, handing over the scriptwork to Erik Arnoux.
