Named after the rue Dupleix, which honours Joseph François Dupleix (1697–1763).
As governor-general of the French East India Company from 1742, he built up French trade in India and fought British influence there, until he was recalled in 1754. He had invested his whole fortune in India and died in poverty in Paris. The street, a path on the Grenelle plain since the 15th century and once the chemin du Gibet ('gallows lane'), took his name in 1807.
