The Adventures of Blake & Mortimer is a Belgian comics series created by writer and comics artist Edgar P. Jacobs. It was one of the first book series to appear in the Franco-Belgian comics magazine Tintin in 1946, and was subsequently published in book form by Belgian comic book publisher Le Lombard. The main protagonists of the adventures are Philip Mortimer, a leading British scientist, and his friend Captain Francis Blake, of MI5. The books' recurring antagonist is the sworn enemy of the heroes, Colonel Olrik, who appears very frequently throughout the series, in almost every book. Their confrontations take them into the realms of detective investigation and science fiction, dealing with themes of time travel, historical events, and espionage. Since Jacobs' death, many new titles of the series have been published by other authors, mainly two separate teams of artists and writers, with the amount of these new editions significantly dwarfing Jacobs' contributions. A television series based upon the series was produced in 1997, entitled Blake and Mortimer. The books by Jacobs himself are generally set in the period of their writing, but those authored by others after his death are set mostly in the 1950s and 1960s. Source: Wikipedia (en)
