Thierry Van Hasselt is a Belgian cartoonist, painter, and publisher. He is renowned not only as an artist but also as a co-founder of Fréon, which later merged with the Parisian publishing house Amok in 2002 to become Frémok, often abbreviated as FRMK. Since the early 1990s, Frémok has been one of the most influential actors in the realm of alternative comics. Within this sphere, Frémok stands out for its innovative approach to graphic literature, breaking away from conventional norms and blurring the boundaries between comics and other art forms. This ethos has shaped a distinctive collection of avant-garde publications where comics intersect with the aesthetics typically associated with fine arts.

Born in 1969, Van Hasselt studied comics at the École supérieure des Arts (Saint-Luc) in Brussels. It was during his time at Saint-Luc that he connected with a group of fellow art students, forming the collective known as Frigoproduction. In 1991, they released the inaugural issue of the anthology Frigorevue as part of a comics-themed exhibition. By 1994, Frigoproduction had evolved into Fréon, launching a new anthology titled Frigobox to widespread acclaim. Published quarterly, Frigobox predominantly featured serialized comics by its core members, including the twins Denis and Olivier Deprez, Vincent Fortemps, Dominique Goblet, and Jean-Christophe Long. Additionally, it showcased works by invited guests such as Alberto Breccia, Éric Lambé, and Alex Barbier, alongside photographs and insightful theoretical articles on the history and contemporary landscape of comics as an art form.
