L'Homme truqué is a short novel by Maurice Renard, initially published in March 1921 in the magazine Je sais tout. Regularly republished in France during the 20th and 21st centuries, it also benefits from numerous publications abroad. Maurice Renard tells the story of Jean Lebris, a soldier who lost his sight during the trench war, returning to his home town. Having acquired superhuman vision following a medical experiment aimed at restoring his sight, he tries to hide his cumbersome secret from those around him. Written in the aftermath of the First World War, the novel features a war cripple. It appears as a pessimistic work, both by its theme - the difficult rehabilitation of a disabled soldier - and by its tragic ending. As such, it bears witness to the trauma suffered by the French population in the aftermath of the war. At the same time, Maurice Renard, leader of the scientific-marvel literary genre, seeks with this tale of scientific imagination to give the reader food for thought. He pushes the latter to question the scientific progress on which he occasionally offers a nuanced look, notably through the question of the superhuman, but also on the existence of the invisible worlds that surround us. In 2013, writer Serge Lehman and cartoonist Gess revisited this classic of the scientifi-marvel genre in a homonymous comic book, transposing the character created by Maurice Renard into a superheroic context. Origin of the work Maurice Renard, cantor of scientific-marvel Maurice Renard is a novelist of the scientific imagination who seeks to theorize a literary genre under the name of "scientific-marvel" novel to promote its emergence. Author of the successful Le Docteur Lerne, sous-dieu (1908) and Le Péril bleu (1911), he assigned in a founding article published in 1909 considerable aspirations to the literary genre, namely to give the reader food for thought through the application of scientific methods to irrational events. During the first quarter of the 20th century, the writer tries to make his readers think about the effects of progress. Thus, Maurice Renard advocates the use of science, no longer as a setting like the scientific novels of Jules Verne, but as a disruptive element that generates a wonderful phenomenon. The war suspended his literary activities, as he was mobilized between August 1914 and January 1919. After the war, his financial problems forced him to devote himself to a more popular literature genre.
