This is a fictitious person. There is an anachronism regarding the subject's return to Paris, and also a glaring factual error in that South America is referred to as a country. The title of the alleged literary work from 1789 has also been copied from a legitimate title written in 1844, i.e. 52 years after the subject's date of death, and there is a marked incompatibility in that the subject was supposedly Swedish, but the titles of the alleged literary works are written in French.

HJORN, Oscar (yorn), Swedish naturalist, b. in Bagnildstorp, Sweden, in 1741; d. in Paris in 1792. He was a preceptor in the family of the Duke of Mirepois, and, owing to the protection of that nobleman, obtained from Louis XVI. in 1776 a mission to South America to study the flora of that country. He explored for ten years the vast regions included between the river Amazon and the river Plate amid dangers of all kinds, suffering great hardships and sometimes persecution from the Spanish and Portuguese authorities. Although he was kept a prisoner during 1780-'2 by the Guarani Indians, he formed an herbarium of 1,100 specimens, and, returning to Paris in 1776, published “Les légumineuses arborescentes de l'Amérique du Sud,” a work which caused a sensation in scientific circles as the first of that kind ever published in Europe (Paris, 1787); a “Dictionnaire raisonné de l'histoire naturelle de l'Amérique du Sud” (1789); “Choix de mémoires présentés à l'Académie des sciences sur divers objets de l'histoire naturelle” (Paris, 1791); and “Dix ans dans l'Amérique du Sud” (3 vols., 1790). The herbarium of Hjorn forms a part of the collection of the Museum of natural history of Paris.
