Ivan Vladimirovitch Chtcheglov (16 January 1933 – 21 April 1998), also known as Gilles Ivain, was a French political theorist, activist, poet, taxi driver and member of both the Lettrist International and Situationist International. He is best known for his text Formulary for a New Urbanism.
Chtcheglov and his friend Henry de Béarn planned to blow up the Eiffel Tower with some dynamite they had stolen from a nearby building site, because "its reflected light shone into their shared attic room and kept them awake at night." He was arrested at Les Cinq Billards on Rue Mouffetard in Paris and committed to a mental hospital by his wife, where he was subdued with insulin and shock therapy, and remained for 5 years. He died in 1998.
