Munchausen syndrome

The name “Munchausen syndrome” derives from Baron Munchausen, a literary character loosely based on the German nobleman Hieronymus Karl Friedrich, Freiherr von Münchhausen (1720–1797). The historical baron became a well-known storyteller in the late 18th century for entertaining dinner guests with tales about his adventures during the Russo-Turkish War. In 1785 German-born writer and con artist Rudolf Erich Raspe anonymously published a book in which a heavily fictionalized version of “Baron Munchausen” tells many fantastic and impossible stories about himself. Raspe’s Munchausen became a sensation, establishing a literary exemplar of a bombastic liar or exaggerator.
