, who became notorious for his brutality, is one of the historical persons that may have inspired Kurtz's persona. Kurtz's persona is generally understood to derive from the notoriously brutal history of the so-called
Congo Free State, a territory that existed as the private property of
King Leopold II from 1885 to 1908 until it was taken over by Belgium and became a Belgian colony. Researchers have suggested more than twenty prototypes for the character of Kurtz. In his book ''
King Leopold's Ghost'', historian
Adam Hochschild suggests that
Léon Rom, an administrator in the Congo Free State, was the principal inspiration for the Kurtz character, citing references as the heads on the stakes outside of the station and other similarities between the two. Hochschild and other authors have also suggested that the fate of the disastrous "rear column" of the
Emin Pasha Relief Expedition (1886–1888) on the Congo may have also been an influence. Column leader
Edmund Musgrave Barttelot, "went mad, began hitting, whipping, and killing people, and was finally murdered". Harold Bloom notes that Kurtz's sophisticated brutality is closer to that of Barttelot's associate, slave trader
Tippu Tip. The rear column's Scottish naturalist,
James Sligo Jameson, who died in the Congo a few months after watching while a slave girl for whom he had paid was killed and eaten by
cannibals, has also been suggested. The expedition's overall leader,
Henry Morton Stanley, the principal figure involved in preparing the Congo for Leopold's rule, may also have been an influence. Conrad's biographer
Norman Sherry judged that Arthur Hodister (1847–1892), a Belgian solitary but successful trader, who spoke three Congolese languages and was venerated by Congolese to the point of deification, served as the main model, while later scholars have refuted this hypothesis. Peter Firchow mentions the possibility that Kurtz is a composite, modelled on various figures present in the Congo Free State at the time as well as on Conrad's imagining of what they might have had in common. A personal acquaintance of Conrad's, Georges Antoine Klein, may also have been a real-life basis for the character. Klein was an employee of the
Brussels-based trading company
Société Anonyme Belge pour le Commerce du Haut-Congo, and died shortly after being picked up on the steamboat Conrad was piloting. Further, means "little" in German, and as Marlow muses in the novella, means "short" in the same language. Conrad also expressed admiration of
Robert Louis Stevenson's Pacific Ocean writings, in particular, the stories "
The Beach of Falesá" and
The Ebb-Tide, as well as the non-fiction account of
Tembinok' of the
Gilbert Islands that appeared in
In the South Seas. All three texts contain
megalomaniacs who manipulate their circumstances and remote settings to assert power over others. It is widely believed that Conrad drew influence from these characters, as well as Stevenson's plot lines when writing
Heart of Darkness. ==In other works==
