The Wikipedia article of the day for October 29, 2016 is Baron Munchausen.
Baron Munchausen is a fictional nobleman created by German writer Rudolf Erich Raspe in his 1785 book Baron Munchausen's Narrative of his Marvellous Travels and Campaigns in Russia. The character is loosely based on a real baron, Hieronymus Karl Friedrich, Freiherr von Münchhausen (1720–1797). Born in Bodenwerder, Electorate of Brunswick-Lüneburg, the real-life Münchhausen fought for the Russian Empire in the Russo-Turkish War of 1735–1739. After retiring in 1760, he became a minor celebrity within German aristocratic circles for telling outrageous tall tales based on his military career. After hearing some of Münchhausen's stories, Raspe adapted them anonymously into literary form, first in German as magazine pieces, and then in English. The fictional Baron's exploits, narrated in the first person, focus on his impossible achievements as a sportsman, soldier, and traveller, for instance riding on a cannonball, fighting a forty-foot crocodile, and travelling to the Moon. The real-life Münchhausen was deeply upset at the development of a fictional character bearing his name, and threatened legal proceedings against the book's publisher. Several concepts and medical conditions have been named after the character, including Munchausen syndrome, the Münchhausen trilemma, and Munchausen numbers.
