Franquin was born in
Etterbeek in 1924.
 Although he started drawing at an early age, Franquin got his first actual drawing lessons at
École Saint-Luc in 1943. A year later however, the school was forced to close down because of the
war and Franquin was then hired by Compagnie Belge d'Animation|CBA, a short-lived animation studio in
Brussels. It is there he met some of his future colleagues: Maurice de Bevere (
Morris, creator of
Lucky Luke), Pierre Culliford (
Peyo, creator of the
Eddy Paape. Three of them (minus Peyo) were hired by
Dupuis in 1945, following CBA's demise. Peyo, still too young, would only follow them seven years later. Franquin started drawing covers and cartoons for Le Moustique, a weekly magazine about radio and culture.
 He also worked for Plein Jeu, a monthly scouting magazine.
During this time, Morris and Franquin were coached by Joseph Gillain (
Jijé), who had transformed a section of his house into a work space for the two young comics artists and
Will. Jijé was then producing many of the comics that were published in the
Franco-Belgian comics magazine
Spirou, including its flagship series
Spirou et Fantasio. The team he had assembled at the end of the war is often referred to as La bande des quatre (lit. "The Gang of Four"), and the graphical style they would develop together was later called the
Marcinelle being an outskirt of the industrial city of Charleroi south of
Brussels where Spirou's publisher Dupuis was then situated.
Jijé passed the Spirou et Fantasio strip to Franquin, five pages into the making of
Spirou et la maison préfabriquée, and from Spirou issue #427 released 20 June 1946, the young Franquin held creative responsibility of the series.
 For the next twenty years, Franquin largely reinvented the strip, creating longer, more elaborate storylines and a large gallery of burlesque characters.
Most notable among these is the
Marsupilami, a fictional monkey-like creature. The inspiration for the Marsupilami's extremely long,
prehensile tail came from imagining an appendage for the busy
tramway conductors the Franquin and his colleagues often encountered on their way to work. This animal has become part of Belgian and French
popular culture, and has spawned cartoons, merchandise, and since 1989 a comic book series of its own. The cartoons have broadened its appeal to English-speaking countries.
By 1951, Franquin had found his style. His strip, which appeared every week on the first page of Spirou, was a hit. Following Jijé's lead in the 1940s, Franquin coached a younger generation of comics artists in the 1950s, notably
Jean Roba and
Jidéhem, who both worked with him on Spirou et Fantasio.
In 1955, following a contractual dispute with his publisher Dupuis, Franquin went for a short stint at rival
Tintin magazine. This led to the creation of
Modeste et Pompon, a gag series which included contributions from
René Goscinny (of
Astérix fame) and Peyo. Franquin later returned to Spirou, but his contractual commitment to Tintin meant that he had to contribute to both magazines, an unusual arrangement in the comic industry. The series was later passed on to authors such as
Dino Attanasio and
Mittéï (Jean Mariette).
In 1957, Spirou chief editor
Yvan Delporte gave Franquin the idea for a new figure,
Gaston Lagaffe (from the French la gaffe, meaning "the blunder"). Initially a joke designed to fill up blank space in the magazine, the weekly strip, detailing the mishaps and madcap ideas and inventions of a terminally idle office boy working at the Spirou offices, took off and became one of Franquin's best-known creations.
However, Franquin soon suffered a period of
depression, which forced him to stop drawing Spirou for a time. This happened between 1961 and 1963, in the middle of
QRN sur Bretzelburg. During this time, he continued to draw Gaston despite ill health, most likely because of the lighter nature of the series. (In one story,
Bravo Les Brothers, Gaston's antics drive his boss
Fantasio to yet another nervous breakdown. In desperation he takes some
anti-depressants which "Franquin left behind".)
In 1967, Franquin passed Spirou et Fantasio on to a younger artist,
Jean-Claude Fournier, and began to work full-time on his own creations.
He was part of the team that developed the concept of
Isabelle, the adventures of a little girl in a world of witches and monsters. The character was named after Franquin's daughter.
Gaston gradually evolved from pure
slapstick humor to feature themes important to Franquin, such as
environmentalism. Franquin also used its characters in paid ad strips he drew, and worked with the strip on and off until his death.
Franquin's later period
The 1960s saw a clear evolution in Franquin's style, which grew more loose and intricate. This graphical evolution would continue throughout the next decade. Soon, Franquin was considered an undisputed master of the art form, on par with the likes of
Hergé and his influence can be seen in the work of nearly every cartoonist hired by Spirou up until the end of the 1990s. Early comic
fanzines from around 1970 featured Franquin's Monsters, individual drawings of imaginary beasts highlighting his graphical craftmanship.
The last, and most radical, shift in Franquin's production happened in 1977, when he went through another nervous breakdown and began his
Idées Noires strip (lit. "Dark Thoughts"), first for the Spirou supplement, Le Trombone Illustré (with other cartoonists like
René Follet) and later for
 With Idées Noires, Franquin showed the darker, pessimistic side of his nature. In one strip, a pair of flies are seen wandering through a strange landscape, discussing the mistakes of their predecessors. In the final panel, we see the landscape is a city made from human skulls, and one fly responds: "Don't be too hard on them, they did leave us such splendid cities". Drawn entirely in black and white, Idées Noires is much more adult-oriented than Franquin's other works, focusing on themes such as death, war, pollution and
capital punishment with a devastatingly sarcastic sense of humour.
Proof of his popular and critical appeal, Franquin was awarded the very first
Grand Prix de la ville d'Angoulême in 1974. Many books by Franquin have been published, many of which are considered classics of the genre. They have been translated in many languages. Several books have been written about Franquin, such as
Numa Sadoul's Et Franquin créa la gaffe, an exhaustive interview with the artist covering his entire career.
Franquin's death in 1997 in
Saint-Laurent-du-Var didn't quite elicit the kind of worldwide posthumous homage
Hergé received. However, 2004 saw the first major museum retrospective of his work, an exhibit called "Le monde de Franquin"', in Paris'
Cité des Sciences et de l'Industrie this exhibition was continued in 2006 in the city where he was born,
Brussels, the latter was fully bilingual (French/Dutch). In 2005, a
Walloon survey elected him as the "16th greatest Belgian ever".
