Short answers, pulled from the story.
Hergé was the pen name of Georges Prosper Remi, a Belgian comic strip artist born on the 22nd of May 1907. He is best known for creating The Adventures of Tintin, one of the most popular European comics of the 20th century, drawn in his distinctive ligne claire style.
The pen name Hergé comes from the French pronunciation of his reversed initials, R.G. His work first appeared under the name Hergé in December 1924, after he had earlier tried out the pseudonyms Jérémie and Jérémiades.
Hergé created Tintin for the children's supplement Le Petit Vingtième, where Tintin in the Land of the Soviets began serialisation on the 10th of January 1929. The character was based partly on his earlier creation Totor and partly on his own brother, Paul.
Hergé worked for Le Soir, a Brussels daily that was under Nazi control during the German occupation of Belgium. After the Allied liberation in 1944 he was arrested and named in a Resistance document called the Gallery of Traitors, though his case was closed on the 22nd of December 1945 with no charges brought.
Yes, Hergé faced repeated accusations of racism, especially for Tintin in the Congo, which depicted the Congolese in a paternalistic style and was later condemned as racist. Biographers such as Benoît Peeters and Michael Farr argued he was no more racist than others of his time, while critic Laurence Grove said he followed prevailing societal trends.
Hergé suffered cardiac arrest on the 25th of February 1983 and died at Brussels' Cliniques universitaires Saint-Luc on the 3rd of March 1983, at the age of 75. He had been diagnosed in 1979 with osteomyelofibrosis, which required increasingly frequent blood transfusions.
The Musée Hergé is located in the centre of Louvain-la-Neuve, a city south of Brussels. Designed by architect Christian de Portzamparc and built for 15 million euros, it opened in June 2009 with eight permanent galleries of original artwork.
