Maurice Watt, presumably a pseudonym, was one of the earliest French artists to draw a science-fiction comic. Watt drew a bloody expedtion to Mars in 1912, of which the survivors stayed on the moon. Three years earlier, he made his debut as a caricatural illustrator in Pages Folles. He was also present in La Vie de Garnison (1910-23), Le Régiment (1912-20) and Le Rire (1915-17).
Watt's SF comics, 'Le Fils de la Terre' appeared in Fillette. For that same magazine, he made 'Papa Fifi' and 'La Bouquetière du Roi'. In 1920, his historical comic 'Janick et Gaël' appeared in Lili magazine. In addition, he drew gags for Le Cri-Cri.
