Following his death, his daughter Christina became the principal heir to his estate. She inherited a substantial fortune and assumed an important role in managing the family’s financial interests. His widow, Jacqueline Kennedy Onassis, also received financial benefits under the arrangements made following his death. The inheritance attracted considerable attention because of the immense value of the Onassis estate and the international reputation of the family.
Christina later established the Alexander S. Onassis Public Benefit Foundation in memory of her brother. The foundation supports educational, cultural, and artistic activities, preserving the family’s name through charitable work. Christina died in Buenos Aires in 1988, at the age of 37. Her death represented another tragedy for the Onassis family and brought further attention to the complicated history of the dynasty.
