Born in Belfort, France on September 3rd, 1967, Luc Brunschwig studied advertising at the University Institute of Technology (UIT) in Illkirch (Alsace).
In 1989, he organized the first "Carrefour de l'Illustration du Livre pour Enfants" with the UIT, where he met Laurent Hirn, for whom he wrote the script for the series Le Pouvoir des innocents (Delcourt).
Still working for the same editor, he tackled the short saga of the Vauriens with Cagniat in 1995 and L'esprit de Warren in 1996. The author of two stories in the magazine Je Bouquine in the mid-1990s, he also devised Nique la crise for the cartoonist Pontarolo (Vents d'Ouest, 1995), and at the Audincourt Festival in 1996 he had another work published, Sixty Bloc, illustrated by Hirn, Crespin and Baudoin, offering a history of the suburbs starting in the 1960s.
After these productions of limited duration, he committed himself to longer series, mainly for the publisher Humanoïdes Associés, with Urban Games (illustrated by Cagniat and Hirn) and Angus Powderhill (illustrated by Vincent Bailly).
His revival and transformation of a script by Mic Mac Adam attracted a great deal of attention at Dargaud and made the author Benn very enthusiastic about this character, whose first adventures had been published during the 1980s in Spirou, with scripts by Stephen Desberg.
At the same time, alongside Neuray, he was composing Makabi, a great modern thriller for the Dupuis collection Repérages.
More recently, Brunschwig has contributed to the rebirth of one of the most eminent figures in Franco-Belgian comics, with Bob Morane: Resurrection.
