Christina Onassis was three years old when the last person who truly loved her was found dead in a bathtub. She was the richest child on earth, raised in a house that belonged to the woman her mother had spent three years trying to remove from her life. She owned a private island in the Ionian Sea and sold it because standing on it made her feel like a stranger. She inherited a billion-dollar empire, and at thirteen, she told a courtroom that if she could burn every dollar of it, she would.

Her name is Athena Onassis, the last surviving descendant of Aristotle Onassis, the most powerful private citizen the modern Greek world ever produced. She is the only child of Christina Onassis, a woman who had $250 million, four failed marriages, a clinical depression diagnosis, and a prescription bottle on her nightstand, and who was found dead in a bathtub in an Argentine suburb at thirty-seven years old. Her daughter was three, asleep in a nursery in Switzerland, seven thousand kilometers away. Christina was born on December 11, 1950, in Manhattan.

Her father was Aristotle Socrates Onassis, a Greek tobacco merchant’s son from Smyrna who had built the world’s largest private shipping fleet through commercial ruthlessness and political pragmatism. Her mother was Athina Mary Livanos, called Tina, the daughter of the founder of the Livanos shipping empire. Christina was the second child; her brother Alexander was three years older. By every account from household staff, the children were raised in extraordinary material comfort and near total parental absence.

Aristotle built his empire, Tina attended its parties, and the children moved between Greece, France, and England following the business, not the school calendar. Christina’s clearest childhood memory was sitting in the back of a car outside a party on the French Riviera at age six, watching through a window as her parents stood in a doorway surrounded by others. She understood, without being able to name it, that her parents did not look at each other. The divorce came in 1960, when Christina was nine.

The cause was Aristotle’s affair with opera singer Maria Callas. Tina filed and took the children; Aristotle did not contest. On the afternoon her mother told her father would not be living with them anymore, Christina did not cry. She went to her room, sat on the edge of her bed, and said nothing for the rest of the evening.

“She already knew,” the housekeeper later said. “She had already known for a long time. ”

In 1968, Aristotle married Jacqueline Kennedy, the widow of the assassinated American president. He told Christina it was a business arrangement, that Jackie’s name would give the Onassis brand legitimacy in American political circles.

He explained it across a dinner table in Monte Carlo as though discussing a tanker contract. Christina was eighteen. She thanked him, ate her dinner, and did not emerge from her room until the following morning. Then came the twenty-nine months.

Alexander died in a plane crash at Athens Airport on January 23, 1973. He was twenty-four, placed on life support, and never regained consciousness. Tina died in September 1974, found in a suite at the Paris home of Stavros Niarchos, the man she had married in 1971. The official cause was acute pulmonary edema; she was forty-five.

Aristotle died in March 1975, weakened by myasthenia gravis and accelerated by grief. Three deaths in twenty-nine months. Between 1975 and 1978, Christina ran the Onassis shipping empire alone. She inherited 55 percent of a fortune then estimated at $500 million, the largest single private inheritance in Greek history.

In 1977, she negotiated a tanker lease arrangement with the Soviet government worth approximately $800 million in current terms. Industry analysts noted it was more commercially advantageous than any deal her father had closed in his final decade. She was one of the most powerful women in global shipping. She was also keeping a doctor’s prescription in her purse and eating alone most evenings.

Christina had been diagnosed with clinical depression by age thirty. Her physicians prescribed barbiturates, amphetamines, and sleeping pills. She had been hospitalized at least once following an apparent overdose. Between 1971 and 1987, she married four men, and all four marriages ended in divorce.

The fourth, the last one, the only one that produced a child, began in 1984. She met Thierry Roussel in early 1983 at a dinner party in Paris. He was thirty, French, the heir to a pharmaceutical fortune. He had his own money, and Christina believed he had no reason to want hers.

He was the most charming man in the room. He listened, asked follow-up questions, talked about her, not the tankers or the foundation. A close friend described watching them together: Christina smiled differently around Roussel. “I was glad to see it,” the friend said.

“I was also, immediately and quietly, afraid. ”

Her lawyer recommended commissioning a private investigation of Roussel’s background before proceeding. She declined. The reason she gave her lawyer was a single sentence.

“If I knew everything, I would not be able to go through with it. ”

They married on March 17, 1984, in a civil ceremony in Paris. Christina was pregnant. What she did not know was that Roussel had an ongoing relationship with a Swedish model named Gaby Landhage, the central private relationship of his adult life for the better part of a decade.

When Christina gave birth to her daughter Athina in Geneva on January 29, 1985, Gaby Landhage was already carrying Roussel’s child. By the calculation of subsequent birth records, Landhage had been pregnant since approximately the autumn of 1984, the first months of Roussel’s marriage to Christina. The boy, Eric Roussel, was born in July 1985, five months after Athina. Christina confronted Roussel.

He confirmed the child existed and described Landhage as a prior arrangement separate from his marriage. Christina did not leave. She did not file for divorce. She stayed.

She adjusted. She decided that what she had was still preferable to what she would have without it. Roussel and Landhage’s second child, a daughter named Sandrine, was born in May 1987, during the third year of the marriage. Christina filed for divorce that same year.

In the same month, she dictated a single amendment to her will. It was not about money. It specified that Athina would be raised in the Orthodox Christian faith and would learn Greek to speak it fluently. She told her trusted legal advisor these were not preferences but requirements.

She said she did not trust what would happen without them in writing. She was right. After the divorce was finalized in 1987, Christina spent the remaining sixteen months of her life moving. She visited Athina at the Swiss estate that had become her permanent home under the custody arrangement.

She called every morning, sometimes twice daily, always at the same time. On one of her last calls, a Thursday in late October 1988, three weeks before she traveled to Buenos Aires, Athina was asleep. Christina left a message with the nanny: “Tell her I know she is going to be all right. She has already survived the worst of it.

”

She arrived in Buenos Aires on November 18, 1988. She ate dinner with her hosts and went to bed at approximately eleven. On the morning of November 19, her maid entered the room and found her in the bathtub. The official cause of death was acute pulmonary edema, the same condition, the same medical vocabulary, that had appeared on her mother’s death certificate fourteen years earlier.

Tina had been forty-five. Christina was thirty-seven. On the nightstand, beside the prescription bottles, was a folded sheet of paper bearing a single name written in Greek in her own handwriting: Athena. It was not a letter or a legal document.

According to the account given years later by someone present that morning, it was a single sentence, the kind a person writes when they believe they will not be in the position to say it in person. The exact wording was never published, at the family’s request. Athina was three years old. She did not attend the funeral.

The decision was made on her behalf by the adults around her. Christina was buried beside her father and brother on the island of Skorpios. Approximately one hundred relatives and close friends attended. Thierry Roussel was among them.

He was the father of the only surviving Onassis heir, and at that moment, the most powerful person in the room, because the only person who had ever had cause to remove him from that position was in the coffin in front of him. Roussel was appointed guardianship. He moved Athina into the house in Lussy-sur-Morges, where Gaby Landhage was already living, where Eric Roussel, born five months after Athina, was already living, where Sandrine Roussel, born in 1987, was already living. The custody protocol Roussel signed contained two binding requirements: Athina would be raised in the Orthodox faith, and she would learn Greek to speak it fluently.

By the time Athina was fourteen, in 1999, she had been raised in a French-speaking household, educated in French-language schools, given a French name as her primary identity. She did not speak Greek. She had not been baptized in the Orthodox tradition. Roussel had violated both clauses of the custody protocol, entirely and for a decade without legal consequence.

In the summer of 1999, Athina stood before a court for minors in Oberengadin, Switzerland, and made a formal statement. She was fourteen. The statement, documented in a court report later referenced by researchers, said that she felt a great aversion to anything Greek, even though she knew her mother, her grandfather, and her fortune came from Greece. She said it in French.

Her father was standing beside her. Athina turned eighteen on January 29, 2003, the day she legally assumed control of her mother’s half of the fortune, estimated at approximately 2. 3 billion euros. In the months before, she had moved out of her father’s house and retained her own lawyers.

What she found in the accounts was partially documented. Roussel had received between $70 million and $120 million across the period of his guardianship, plus an annuity of approximately $1. 4 million per year drawn from the estate. He had also been convicted in an Athens court in 1998 on charges of perjury and false denunciation for making sworn accusations against the foundation trustees that were found to be demonstrably false.

The sentence was five years, reduced and effectively suspended. He served no prison time. The legal resolution between Athina and Roussel was reached between 2003 and 2004. The precise terms were never fully disclosed.

What the foundation’s president confirmed to an investigator was the essential outcome: Roussel had lost. The fortune was under Athina’s control. She was twenty years old. She had done in two years what her mother had never been able to do in four marriages.

She had removed him. In the autumn of 2003, Athina applied for a renewal of the Greek passport her mother had obtained for her at birth. In January 2004, she joined a Greek equestrian club, registering under the name her mother had used at her birth: Athina Christina Roussel. Within months, she was competing internationally under the name Athina Onassis, representing not Switzerland or France but Greece, the country her father had spent eleven years teaching her to regard with aversion.

On December 3, 2005, Athina married Alvaro Alfonso de Miranda Neto, a Brazilian Olympic show jumping medalist, in São Paulo. Thierry Roussel was not present. Gaby Landhage was not present. Following the marriage, Athina formally assumed the name Athina Onassis.

The name Roussel was gone. She was, for the first time, legally and publicly what she had always been: the last Onassis. In 2013, Athina sold the island of Skorpios for $153 million. She stood on the island before the transfer was completed.

She had not visited often. Her grandfather’s grave was there. Her mother’s grave was there. She had not grown up in a world that taught her to sit with those graves.

She had not grown up in a world that taught her Greek. She stood on the island at twenty-eight, having sold it as the last person in the direct Onassis line who would ever stand there as its owner. In 2016, Alvaro de Miranda Neto was alleged to have been unfaithful. Athina filed for legal separation.

The divorce, finalized in November 2017, was settled in her favor; the prenuptial agreement held. After the divorce, she moved to Greece. In a 2005 interview, she had said she never had a mother, that she had “an absence where a mother was supposed to be. ” In 2017, at thirty-two, she moved to the country that absence had come from.

She is now forty-one, a competitive show jumper who has competed internationally under the name Onassis. She has made rare public appearances since her divorce, was elected to the board of a French supermarket company in 2024, and has not given a major interview in years. Her mother left her a sentence on a folded piece of paper, in Greek, in a room seven thousand kilometers away, on the last night of her life. We will never know exactly what it said.

But we know who read it.
