Lewis Trondheim was first known as the author of Les formidables aventures de Lapinot (later to be translated to English as The Spiffy Adventures of McConey). He invented the character in the late 1980s as a way to learn cartooning. The result was an initial 500 page graphic novel, Lapinot et les carottes de Patagonie. All the while, he was publishing short stories for the satirical French magazine Psikopat.

After his book Slaloms was awarded what was then called the Alph'Art Coup de coeur (First comic book prize) in 1993, Trondheim was offered to bring his burgeoning series to a major publisher, Dargaud, while he continued churning out more personal books for L'Association and other independent French publishers such as Cornélius. From there onwards, Trondheim began to enjoy a steady rise in popularity.

The following years represented a period of increasing activity, as Trondheim began to work on many different projects. He first created La Mouche ("The Fly") for the Japanese market, and then redrew a French version from scratch, after which the character was adapted as an animated cartoon.

Trondheim's greatest breakthrough after Lapinot is arguably Dungeon (in French, Donjon), an ambitious series which he created with Joann Sfar, and which has enjoyed a fair amount of popular success.

Trondheim's "retirement"

In 2004, after a long and intensive period during which he steadily released new books at a frantic pace, Lewis Trondheim announced he was more or less retiring from the world of comic strips, stating he did not want his passion to become a "job". He did draw and write a few stories within the following year, including a book reflecting on his decision to slow down, though the releases occurred at a much slower pace.

It has long been speculated he used this time partly to create another ambitious work, Le blog de Frantico, which was a comic strip blog published daily on the web for a whole year under the Frantico pseudonym. In interviews and on his web sites, Trondheim alternately admits and denies having written Le blog de Frantico, though another author, Sébastien Lesage eventually stepped up and claimed to be the real author, saying he had asked Trondheim to help him maintain the mystery. To this day however, the true identity of Frantico remains unconfirmed.

Another recent Trondheim occupation is that of editorial director at Delcourt, where he direct Shampooing, a collection of comic books for young readers.

In 2006, Trondheim was awarded the Grand Prix de la ville d'Angoulême at the Angoulême International Comics Festival, arguably the most prestigious award in the field.

Trondheim has written or drawn more than a hundred titles, spanning a large spectrum of genres; some of the most notable are:

• The spiffy adventures of McConey (Les formidables aventures de Lapinot; 10 official volumes), which mix satire and fantasy. The main characters are all animals: for instance McConey is a shy and easygoing rabbit, while Richard is an engaging cat with a loud mouth and a knack for getting into trouble. The stories alternate between modern France and stock historical settings. The recurring characters in the series can be thought of as actors who don't always play the same people, but always play the same type of roles.

• Dungeon (Donjon; more than 30 volumes), co-written with Joann Sfar, an extremely ambitious series which attempts to chronicle a Dungeons & Dragons-like dungeon through three separate epochs. The tone varies from heroic to comic to rather dark.

• Several children comics, among them: Le roi catastrophe (8 volumes), drawn by Fabrice Parme, a series about a boy king; Monstrueux (3 volumes), featuring a young French family resembling Trondheim's, and their pet monster Jean-Christophe; Kaput and Zösky (2 volumes), featuring space aliens, which in recent years, has been converted into a television program; and more recently A.L.I.E.E.E.N., an "alien children book" Trondheim jokingly claims to have found in a country field while on vacation.

• Collections of short, modern comic strip fables, sometimes starring simplified, potato-shaped characters, the bulk of which has been published by L'Association (Genèses apocalyptiques, Non, non, non, Le pays des trois sourires, etc.)

• Autobiographical comics, such as those collected in Approximate Continuum Comics, which later formed his book Approximativement; as well as his more recent Carnet de bord series (3 volumes). Newer autobiographical comics are regularly published on his blog under the title Les petits riens (serialized in English paperback volumes as Little Nothings).

• Various conceptual comics, such as Le dormeur and Psychanalyse, both of which were created entirely with a single photocopied panel, while Bleu and La nouvelle pornographie are both billed as "abstract comic books". After Psychanalyse, Trondheim was challenged by J.C. Menu to write a story with only 4 different panels, drawn by Menu. After some strips, Trondheim asked for four more panels, and wrote the highly dense comic book, Moins d'un quart de seconde pour vivre. Such constrained writing achievements, reminiscent of OuLiPo writers, were a huge incentive for OuBaPo's creation.

About English translations

NBM has published Dungeon, both in comic book and graphic novel formats, as well as Little Nothings, a collection of autobiographical one-page vignettes. English versions of A.L.I.E.E.N.
