Summary
Updated 2026-08-18

Thierry Roussel is a French businessman. He was the fourth husband of Christina Onassis, daughter of well-noted Greek shipping magnate Aristotle Onassis, and the only man with whom she had a child, daughter Athina Onassis Roussel. Roussel is best known as the controversial former co-trustee of his eldest child's famous fortune and for having been involved in a number of legal entanglements with the four Greek trustees of that fortune. These disputes were mostly ended in 1999 by the court-ordered transfer of the administration of Athina's trust to a private auditing firm.
