Franz Drappier, better known under only his first name, studied Plastic Arts at the Institut Saint-Luc in Brussels and Fine Arts in Mons. He worked as an illustrator from 1966 until he began making comics in 1969.
After drawing several historical comics for both Spirou and Tintin, Franz made the humorous series 'Korrigan' with writer Vicq in Tintin. In 1972, he briefly appeared in Pilote, and he created 'Les Aventures de Christopher' with writer Yves Duval in Le Soir Jeunesse.
The same year, Franz joined the art studios of Henri Desclez, where he made the drawings for seven episodes of 'Commissaire San-Antonio'.
Starting in 1975, his name appeared more frequently in Tintin. He took over the series 'Jugurtha' from Hermann and he started his own series 'Hypérion' with scripts by André-Paul Duchâteau and 'Lester Cockney', for which he wrote the scripts himself. Besides his several series, Franz also drew independent comics, such as 'Bruxelles, Mille Ans d'Épopée', '1830, La Révolution Belge', 'Captain Tom' and 'Pur-Sang'.
He began an association with the magazine Charlie Mensuel in 1982, where he started the series 'Thomas Noland' with scriptwriter by Daniel Pecqueur. Two years later, he did several short stories scripted by José-Luis Bocquet and Jean-Luc Fromental in Métal Aventure.
