Monique Roosmale Nepveu (born 1940) is a French billionaire and a prominent member of the Louis Dreyfus lineage.

Early life

Originally named Monique Louis-Dreyfus, she is one of the three offspring of Jean and Jeanne Madeline (née Depierre) Louis-Dreyfus. Her brothers and sisters include Robert Louis-Dreyfus and Marie-Jeanne Meyer. Her paternal heritage is Jewish, while her mother practiced Roman Catholicism. She descends from Léopold Louis-Dreyfus, the founder of the Louis-Dreyfus Group, which initially traded wheat in Alsace before diversifying into shipping, oil, and other commodities. Her grandfather, Louis Louis-Dreyfus, was a member of the French Parliament during the era of the French Third Republic.

After her brother Robert passed away, his widow Margarita Louis-Dreyfus acquired a 60% ownership in the Louis Dreyfus Group, later raising it to 65% by 2012. Monique retains a 12.5% share in the enterprise, which contributes to her billionaire status.

Personal life

She was wed to Louis Jan "Jack" Roosmale Nepveu (1928–2013), a Dutch commoner who was born in Pretoria, South Africa. Together, they have two children.
