Studios Hergé
The Studios Hergé were, between 1950 and 1986, a SARL company consisting of Belgian cartoonist Hergé and his collaborators, who assisted him with the creation of The Adventures of Tintin and derived products. Over the years, the studios had between 12 and 50 employees, including some prestigious artists like Jacques Martin, Bob de Moor and Roger Leloup. Every creation produced by the studios was attributed to Hergé alone, except for three albums of Quick & Flupke which are attributed to Studios Hergé on the cover. In 1987, the Studios were disbanded and transformed into the Hergé Foundation by Fanny Rodwell, a former colourist at the Studios and Hergé's widow. History 
The Studios Hergé were created by Hergé in 1950 to assist him with the production of The Adventures of Tintin. They permitted him to focus on the creation of new stories by handing over some aspects of the artwork, particularly the colouring, which Hergé had never really mastered and which in the 1940s was done by Edgar Pierre Jacobs, and the drawing of decors. Technical elements required much documentation and a specific drawing technique, making such assistance worthwhile. The Studios were created when Hergé worked on Destination Moon, an adventure permeated by technology. The influence of some studio members on the stories is also present. For example, Jacques Martin claims to have introduced a number of burlesque gags that don't correspond to Hergés style of humour. The story of the "gag page" 
An anecdote well known among tintinophiles is indicative of the atmosphere in the Studios in those years. When Hergé was on a holiday in December 1965, the two main collaborators, Bob de Moor and Jacques Martin, created a fake Tintin page, completely in the style of the master, which they sent to the Swiss weekly magazine L'Illustré. It was published there as an installment of the next Tintin adventure. Jacques Martin: "I first invented a short story, and then composed the page and placed the characters. Next, Bob de Moor completed the backgrounds, which I had sketched, and we both inked the page: he did the backgrounds, I did the characters. Apparently, Hergé didn't react immediately upon discovering this, but probably preferred let matters stand as they were with this joke, which, according to some, was a true indication of the state of mind of the collaborators who wanted to be more involved in the creation of the adventures of Tintin. The gag page depicts an airport scene comparable to some sequences in Destination Moon and The Calculus Affair, actually closely resembles a page by Hergé, with only some tintinophiles able to spot some typical style elements of De Moor and Martin. The page can be seen at Tintin est Vivant !. The Studios after Hergé 
After the death of Hergé in 1983, his widow Fanny Remi, who started working with the studios as a colorist in 1956, inherited the rights to the works of the author, but not the rights to the derived works, which belonged to Hergé's friend Alain Baran of the company Tintin Licensing, who later sold the rights to the television channel Canal+. Fanny followed the wishes of Hergé. who didn't want The Adventures of Tintin to be continued after his death. Some doubt exists about Tintin and Alph-Art, however, left unfinished by Hergé at his death and at first handed over to the Studios to be finished by De Moor. Fanny Remi then changed her mind and decided to publish just the sketches by Hergé, to the disappointment of De Moor. There is also some hesitation about Quick & Flupke. Less popular than Tintin, Hergé had not left any clear instructions about a continuation of the series. Perhaps more to keep the Studios running than for a truly artistic reason, Fanny accepted the proposal of Johan De Moor, son of Bob and recent arrival in the Studios, to restart the series. He created an album of new strips while the Studios updated a number of old strips never before published in colour. Three albums appeared in 1985, the only ones to officially credit the Studios Hergé on the cover and inside. Fanny then announced that the series would end there and that the Studios would be closed. The activities of the Studios ceased soon thereafter, but not before finishing some projects of derived products and publicity work. In 1986, the Studios Hergé were replaced by the Hergé Foundation, solely occupied with the rights of the series. In 1988, the giant fresco in Stokkel/Stockel metro station was inaugurated, based on sketches by Hergé, which were finished by the Studios. Members of the Studios 
This non-exhaustive list features the principal members only. Artists 
Bob de Moor (1950–1986)
He entered the Studios Hergé on 5 April 1950, and soon became the first assistant, a position held by Edgar P. Jacobs in the previous decade. Reputed for his perfect imitation of the style of Hergé, he supervised the totality of the album production together with Hergé. He was also charged with the creation of all derived products featuring the heads of Tintin or Snowy. Jacques Martin (1947?–1972)
 Creator of Alix, close to Hergé, he joined the Studios mainly as an assistant to the stories, starting with The Calculus Affair. He worked with Hergé until 1972, notably on The Red Sea Sharks and Tintin in Tibet

Works of the Studios 
All works realised under the name of Hergé since 1950 can be considered as works of the Studios. This is a non-exhaustive list of those works where the Studios played a major role, either by colouring, drawing of backgrounds, or by completely replacing Hergé. However, it is difficult to correctly judge the role of the contributors, as Hergé and, later, his rights-holders minimized their work. There is debate over a number of albums, mainly Tintin and the Picaros and the third version of The Black Island, where some believe that Bob De Moor completely redrew the entire album. With the Jo, Zette and Jocko adventure The Valley of the Cobras, Jacques Martin is sometimes said to have drawn the whole of the album. Albums
