Born in Liège in 1996, Jean Cremers' parents directed him towards the same schooling as his 4 other brothers and sisters. It was only after completing his studies in general secondary education with a science-language option that he decided to change direction. Thus, he began his higher education in comics at Saint-Luc Liège. In February 2020, he won the young talent grand prize in the "Quai des bulles" competition in Saint-Malo. He graduated with great distinction with a Master's degree in comics from the Royal Academy of Fine Arts in Liège and published his first graphic novel with Le Lombard.
