Jackal (The Day of The Jackal) - Identities

Identities

• Unknown: The Jackal's real name is never revealed. Until he chooses his new codename — "Jackal" — he is referred to as "the Englishman". At the end of both the novel and the movie Scotland Yard detectives are still wondering who he was. One apparent inconsistency in the novel is that when his employers try to call him at his London apartment to warn him his cover is blown — and just miss him — there is no indication that the French Intelligence services make note of the London number and thus have a real lead to the Jackal's identity. However, he could have held the Mayfair flat under an assumed name as well, in which case his anonymity is truly airtight.
• Unknown: The Jackal signs in at the British Museum using his "habitual false identity". In the film version of this scene, all that is seen of this name is "J".
• Alexander James Quentin "Alex" Duggan: This is the name of a boy who was born in 1929 but died aged two and a half in a car accident. The Jackal obtains Duggan's birth certificate under false pretences and applies for a passport in this name but with his own photograph and details. In the 1973 film the child's name is changed to Paul Oliver Duggan and his death certificate states that he died of diphtheria.
• Per Jensen: A pastor from Copenhagen who bears a resemblance to the Jackal but is older with iron grey hair and metal-rimmed spectacles. The Jackal steals Pastor Jensen's passport from his London hotel room and adopts the disguise after the French police discover his Duggan identity. In the 1973 film, the character's name is Per Lundqvist and he is a schoolteacher; there is no Marty Schulberg character, so it is as Lundqvist that The Jackal pretends to be gay in order to stay at Jules Bernard's flat.
• Martin "Marty" Schulberg: A student from Syracuse who bears a resemblance to the Jackal but is younger, with chestnut brown hair and heavy-rimmed executive spectacles. The Jackal steals Schulberg's handgrip containing his passport and adopts the disguise when he realises the police must be onto Jensen. In the book, as Schulberg, the Jackal pretends to be gay to slip past French security.
• Andre Martin: A fictitious French war veteran from Alsace-Lorraine, Martin is in his late 50s and has only one leg, necessitating walking around with an aluminium crutch. The Jackal becomes Martin — complete with French identity card and mutilé de guerre card courtesy of a Belgian forger — by dyeing his hair grey and cutting it badly, and swallowing a couple of pieces of cordite to make himself sick and affect a pale complexion.
• Charles Calthrop: Charles Calthrop is the name of a former small-arms salesman who was in the Dominican Republic at the time Rafael Leónidas Trujillo was shot. The SIS later heard a rumor that Calthrop has helped the partisans kill Trujillo by shooting the driver of his armoured car, causing it to crash. In the book, the British police originally think Calthrop is the Jackal's real name, until the real Calthrop shows up at the end, after the Jackal's assassination attempt was thwarted. The authorities were misled by the fact that chacal (i.e., Cha Cal) is French for "jackal". When the Jackal learns the French are looking for a Charles Calthrop, he doesn't acknowledge this as his real name. In the movie, however, the OAS mention that the Jackal killed Trujillo, implying that The Jackal may have borrowed Calthrop's identity while in the Caribbean or may just have become mixed up with him.

In any event, it is suggested that the British stumbled across the Jackal's false identity of Duggan by blind luck and that the Jackal may not even have been an Englishman.
