This is probably the most Belgian knows around the world ! The young Belgian reporter is the hero of a series of classic comic books created by the Belgian artist Georges Rémi (1907–1983), more know asf Hergé (R G...).

The serie is the most popular European comics, with translations published in more than 80 languages and more than 350 million copies sold. Its popularity around the world has been attributed to its "universal appeal" and its ability to transcend "time, language and culture."
was first published in a children's supplement to the Belgian newspaper "le 20ème siècle" on January 10, 1929.
Later, popular additions to the cast included the grumpy Captain Haddock, the highly intelligent but hearing-impaired Professor Calculus (Professeur Tournesol in French) and other supporting characters such as the incompetent detectives Thomson and Thompson (Dupont et Dupond in French as Dupont is a family name usual as Smith or Jones).
Hergé's death on 3 March 1983 left the twenty-fourth and final adventure "Tintin and the Alfa Art" unfinished. 
Here below, some of his adventures.
