In 2007, a New York library found Tintin in the Congo racially offensive and moved it to a secure back room. The UK Commission for Racial Equality asked for it to be removed from sale because of “hideous racial prejudice,” and a Congolese student in Belgium started a complaint against the book. For Tintin’s creator Hergé, the pen name for Belgian Georges Prosper Rémi (1907-83), Congo was a naive work, influenced by stereotypes and misconceptions common in Europe when it was first published (1930).1

Despite the older Hergé’s efforts to offer a progressive view of himself,1 2 the Tintin books have been accused of several forms of prejudice. The depiction of Africans in Congo and in The Red Sea Sharks suggested racism. The Shooting Star, published while the holocaust was taking place, was accused of anti-Semitism because a first version featured greedy Jews and a villain has an unintended Jewish surname. Misogyny was suspected because rotund Bianca Castafiore is the only remarkable feminine character. And animal rights activists deplore wildlife carnage in Congo.
