Dr. J.W. Müller Doctor J.W. Muller Dr. J.W. Müller is a character from The Adventures of Tintin series of classic comic books drawn and written by Hergé . He is a villainous doctor , whose main appearance was in The Black Island as director of a psychiatric clinic ( which he also used to dispose of his enemies by giving them a `` treatment '' making them insane ) , which was his cover for his activities as member of a group counterfeiting banknotes . His chauffeur Ivan is also a member of the gang ; the name implies that Ivan is a White Russian , exiled by the Bolshevik revolution . Later , Müller appears in Land of Black Gold as Professor Smith -- working once more to destabilize the world economy and contaminate British fuel supplies in the Middle East ( this would be changed in subsequent issues where the setting was moved from British Palestine to the fictional Gulf state of Khemed ) . His final return was in The Red Sea Sharks under the pseudonym Mull Pasha , where he had assumed the role of an advisor to the usurper regime in Khemed , a clear allusion to British General John Bagot Glubb .
