In 1884, Dupont became the supplier to one of the world's largest shops – Les Grands Magasins du Louvre – while maintaining his private clientele.

Dupont transferred its workshops from Rue Dieu [fr] in Paris back to the family's hometown of Faverges in Savoy in 1924.

In 1987, the company was sold to Dickson Concepts, a Hong Kong retailer of fashion products, watches and jewellery,[1] as part of a restructuring plan announced by Gillette.

The company's first serially-produced lighter was created in 1941 and was made of aluminium, as brass was used as a strategic metal restricted for war purposes only.
