Named after the place and rue Saint-Fargeau, after Louis-Michel Lepeletier de Saint-Fargeau.
Lepeletier (1760–1793) was a deputy of the nobility who became a revolutionary. 'Saint-Fargeau' was part of his title, from the family estate in Burgundy, but his family also owned a château de Saint-Fargeau here: the street began as a path through its park. In 1790 he had the Assembly vote that citizens bear only their family name, and signed simply Michel Lepeletier.
