Lewis Trondheim

His works often feature witty dialogue and characters in surreal or darkly humorous situations, where comedy may intertwine with tragedy. Working with several genres such as fantasy, the supernatural, experimental, autobiographical, or children's stories, Trondheim has contributed to more than 150 books, both as an artist and a writer.

Lewis Trondheim was first known as the author of Les formidables aventures de Lapinot. 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 saw further success following Lapinot in Dungeon (in French, Donjon), a series created alongside Joann Sfar.

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. At that time, in 2005, Trondheim began Le blog de Frantico, which was a blog BD (French webcomic in blog format) published daily on the web for a whole year under the pseudonym Frantico. The webcomic was presented as an autobiographical work, chronicling the daily life of a single 30-year-old graphic designer and aspiring cartoonist, living in Paris. In interviews and on his web sites, Trondheim alternately admitted and denied having written Le blog de Frantico, while graphic designer Sébastien Lesage stepped up and claimed to be the real author, saying he had asked Trondheim to help him maintain the mystery. Trondheim went on and authored other webcomics under the alias Frantico, such as Nico Shark and Mega Krav Maga. The true identity of Frantico remained a subject of speculation until a retrospective exhibition in 2020 confirmed Trondheim as the author of Le blog de Frantico. Another recent Trondheim occupation is that of editorial director at Delcourt, where he manages 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, one of the most prestigious awards in the field. That same year, Trondheim began the autobiographical webcomic Les Petits Riens (Little Nothings), published on his personal website, in line with his earlier works Approximativement and Carnets de bord. Les Petits Riens was eventually published as books by Delcourt, in Trondheim's own collection Shampooing; as of 2024, the series counts nine volumes.

Beginning in the late 2000s, Trondheim worked as a writer for several graphic novels and comics, such as Célébritiz with artist Ville Ranta, Omni-visibilis and Wichitas with artist Matthieu Bonhomme. He also stepped down from his role as artist on the series Donjon Zénith, to work as a writer along with Joann Sfar, while Boulet took over as artist. In 2011, Trondheim began a new fantasy series Ralph Azham, which as of 2024, counts ten volumes. In 2016, he began the science fiction comics series Infinity 8, initially published in a format inspired by American comic books, with Trondheim working as a writer in collaboration with other writers and artists.

Trondheim explained his choice of pseudonym after the Norwegian city of Trondheim as follows: "As a last name I wanted to use a city's name, but Lewis Bordeaux or Lewis Toulouse didn't sound so good. Then I thought about this city, Trondheim… Maybe someday I will publish a book under my real name, in order to remain anonymous." In 1993, he married Brigitte Findakly, a comics colorist and writer.

Two volumes of McConey have been published in English by Fantagraphics in editions close to the original. In 2018, Dargaud also began releasing English translations with the title The Marvelous Adventures of McConey under the Europe Comics label. As of April 2018, three volumes have been published. Fantagraphics has additionally published a range of shorter pieces by Trondheim in the comic The Nimrod. 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. (retitled A.L.I.E.E.E.N.) and Le Roi Catastrophe (retitled Tiny Tyrant) have been published by First Second. The complete Ralph Azham series has been published in four volumes by Super Genius, an imprint of Papercutz.
