After studying business administration at the Solvay Brussels School of Economics and Management, he worked as a journalist and in the marketing department of Philips. In the meantime, he started writing, and one of his first scripts was adapted by Paul Cuvelier in 1968. This erotic comic named Epoxy was published by the controversial publisher Éric Losfeld, who prior to that also had published likeminded comics like Jean-Claude Forests Barbarella and Robert Gigis Scarlett Dream. In 1976, Van Hamme became a full-time writer, and in the next few years he published seven novels and some movie scripts, e.g. for Diva.
Thorgal, XIII and Largo Winch
Van Hamme's main breakthrough came in 1977, when he created the Viking hero Thorgal for Grzegorz Rosiński, a relatively unknown Polish comic artist. The mix of medieval legends and heroic fantasy soon became a huge success in the Franco-Belgian comics magazineTintin. The duo won major awards in the French and Belgian comic book industry. In the next decade, Jean Van Hamme created two new bestselling series, XIII with William Vance and Largo Winch with Philippe Francq. Other series like Les maîtres de l'orge and Chninkel have received more critical acclaim but lower sales. The fame of Van Hamme as one of the major comic authors of Europe is quite established. The artists he works with draw the characters in a realistic style, even if the stories themselves tend to verge towards fantasy. Les maîtres de l'orge and Largo Winch have both been made into a TV series, and XIII, Thorgal, and again were the basis for computer games.
Blake and Mortimer
After the death of Edgar Pierre Jacobs, when the last unfinished story of Blake and Mortimer was completed by Bob de Moor, the editor asked Van Hamme to write new stories. The first one, The Francis Blake Affair, appeared in 1996 and was a huge success, and Van Hamme has since created two more Blake and Mortimer stories. In 2002, Jean Van Hamme announced his intention to write fewer comics, and to concentrate more on theatre and film scripts, but seems to have changed his mind again and has since created two new stories. In 2006, he ended his run on Thorgal with album 29, Le Sacrifice. He has also announced his intention to create a spin-off series of Thorgal, focusing on his son Jolan. In fact, a new duo, Grzegorz Rosinski and Yves Sente continued the serie with four more albums which constitute the "cycle of Jolan" Van Hamme is one of the best selling European comics writers, with many of his series in the best selling lists each year. In 2006, Van Hamme's final volume of Thorgal placed fifth in the French list with 280,000 copies published, while Lady S., with Philippe Aymond, had 90,000 copies. In 2005, XIII and Largo Winch shared the fourth place with 500,000 copies each. In 2010, he was the second-bestselling author of comics in France, after Christophe Arleston but before Albert Uderzo and Hergé, with 1.05 million copies sold.
