Thierry Bouüaert got his artistic talents from his grandfather, who was a painter. Throughout his childhood, Bouüaert drew comics, based on his favorite television shows. He decided to become a professional comics artist in 1986. He studied at the Saint-Luc in Brussels for three years, and took courses in comics at the Académie de St. Gilles. During his studies, he did his first illustration work. After his education, he illustrated articles and summaries in Spirou magazine. He also did some mini-books, using the pseudonym Wilbur H. Dusquesnoy. He was then assigned by publisher Claude Lefrancq to take over the 'Edmund Bell' series from René Follet. Bouüaert illustrated only one album in 1993, and the series was cancelled afterwards. He teamed up with Mauricet, a friend from the Academy, to start a project at Glénat publishers. The publisher ended the contract however, and the project was never realised. A bit disappointed by the comics world, Bouüaert then took on painting, which he continued to do for four years. He returned to comics with the series 'Le Style Catherine', that appears at Bamboo publishers.
