Jérôme Hamon was born in 1977. A graduate of the Rouen Business School and a university in the United States, he began his professional life in New York as a financial analyst. Two years later, convinced that his future was elsewhere, he left the world of finance and traveled around the world for a year. It was during these reflective travels that his imagination ran wild, giving birth to many stories that would haunt him for years. Returning to France, he worked in cinema and video games for a bit before finding himself working at France Télévisions. He took this opportunity to develop some of his ideas into several short film and comic book projects. In 2008, he presented his first comic book scripts in Angoulême and met the cartoonist Marc Van Straceele, with whom he would sign his first project a year later on Yokozuna, a graphic novel about the sumo world in Japan. Following that publication, he began working on Nils with artist Antoine Carrion. Since then, he has written several popular books, including Dreams Factory and Green Class.
