Henri Beaufour

Henri Beaufour owes his fortune to his stake in Ipsen, a French pharmaceutical giant that sells more than 25 drugs in 115 countries.

Founded in 1929 by grandfather Henri Beaufour, the family's 76% share of Ipsen was split between 3 siblings when father Albert Beaufour died in 2000.

Henri and his sister Anne now control about 52% of Ipsen, which generated 2022 revenues of more than $3.4 billion.

Sister Veronica sold her 6% stake.

Henri holds a bachelor's degree from Georgetown University, where he remains a prominent donor.
