Professionally, Larsson was a graphic designer for Tidningarnas Telegrambyra, a Swedish news agency, but he devoted much of his time to investigative journalism, political activism, ethics causes and (to throw a curveball here) the promotion of science fiction. A member of the Communist Workers League and editor of a Trotskyist journal, Fjarde internationalen, Stieg Larsson put his political beliefs into action by founding the Expo Foundation, a Swedish organization formed to counteract racist and extreme right-wing Swedish groups. He was the editor for this foundation’s magazine, entitled Expo, which is more than a coincidence as the character, Mikael Blomkvist, also publishes a magazine, Millenium, in Larsson’s books.
Karl Stig-Erland Larsson was born in the northern town of Skelleftea, Vasterbotten, Sweden in 1954, but changed the spelling of his name to Stieg as an adult. He was intimately familiar with the culture, landscape and “personality” of the north, having been raised in the country by his grandparents. This knowledge is apparent in his descriptions of the towns and countryside in The Girl with the Dragon Tattoo. As a young man he pursued interests in photography, and he enjoyed reading science fiction and mysteries.
His efforts to expose racism, neo-Nazism and extremist groups active in Sweden garnered him numerous death threats. For self-protection, he and Eva Gabrielsson, his partner of 32 years, sought to hide their personal information and address as much as possible, and this is why they never married because under Swedish law a married couple must publish their address. The fact that they were not married became a legal issue after Larsson died of a sudden, massive heart attack. Swedish law did not recognize Gabrielsson as his wife, and Larsson’s estate went to his father and brother, neither of whom were close to him nor had the intimate understanding of Larsson’s writings as did Eva Gabrielsson. The Guardian Observer just published an interesting interview with Gabrielsson which provides more insight into Larsson’s life and literary pursuits, which I recommend you read.
Stieg Larsson died having completed three books which he had hoped to turn into a long series. Known as the Millenium series, they are The Girl with the Dragon Tattoo (Swedish title being Men Who Hate Women), The Girl Who Played with Fire, and finally The Girl Who Kicked the Hornet’s Nest (Swedish title being The Aircastle that Blew Up.) The first book has been released in film form by Swedish and English companies and the next two books are to be turned into television productions. The poster for the Swedish film is illustrated below, giving you some sense of how the characters have been portrayed on film.
