However, their marriage was not without difficulties. Their different lifestyles, personal expectations, and family responsibilities reportedly created tensions. Onassis continued to have connections with Maria Callas, and his relationship with Jacqueline became increasingly complicated. Despite these challenges, they remained married until his death in 1975. Jacqueline inherited financial benefits from their marriage, although Onassis’s daughter Christina was the principal beneficiary of his estate.
One of the greatest tragedies in Onassis’s life was the death of his son, Alexander Onassis, in January 1973. Alexander died following an airplane crash in Athens at the age of 24. He had been involved in his father’s business and was considered a possible successor to the family empire. His death deeply affected Onassis. The loss of his son was a devastating personal blow, and it contributed to the difficulties of his later years. Onassis himself died on March 15, 1975, in Neuilly-sur-Seine, France, at the age of 69, following respiratory failure associated with myasthenia gravis.
