Marie-Hélène Habert-Dassault inherited a share of the Dassault family fortune after her father Serge Dassault died in 2018 and remains active in the family group through communications, sponsorship and supervisory-board roles. [1][2]
Her wealth comes from a multigenerational Dassault inheritance
Forbes identifies Marie-Hélène Habert-Dassault as an heir to the Dassault aerospace and software fortune, inherited with her siblings after the death of their father Serge Dassault in 2018. [1]
The family's industrial base predates her generation: Forbes traces the aerospace business to her grandfather Marcel Dassault, who founded the company that became Dassault Aviation. [1]
That history makes inherited family ownership the clear economic foundation of her billionaire wealth rather than a business or investment platform she created independently. [1]
She has remained active in family-group governance
Forbes says Habert-Dassault previously served as president of the supervisory board of the family-controlled Dassault group before stepping down from that post in 2019. [1]
Dassault Group currently lists her as director of communications and sponsorship and as a member of the supervisory board, supporting an active stewardship role without establishing material value creation comparable with the inherited family fortune. [2]
