Aristotle Onassis: His Marriages, Fortune, and Love Life

Few billionaires have inspired as much fascination as Aristotle Onassis, who married a former First Lady, carried on a decade-long affair with an opera icon, and left behind a fortune that sparked bitter disputes. Here’s a look at the relationships that defined his later years and the financial settlements that followed, with source-backed facts separating myth from reality.

Born: January 20, 1906, Smyrna, Ottoman Empire ·
Died: March 15, 1975, Neuilly-sur-Seine, France ·
Net worth at peak: Estimated $500 million to $1 billion (1970s) ·
Known for: Shipping magnate; Olympic Maritime; marriage to Jacqueline Kennedy

A quick overview of Onassis’s vital statistics reveals how one man built an empire that touched the highest echelons of power.

Why did Jackie Kennedy really marry Aristotle Onassis?

Financial motivations

• The marriage contract between Onassis and Jackie Kennedy included a lump sum and a yearly allowance. After Onassis’s death, Jackie received a lump sum of $3 million and an annual allowance of $150,000 (RR Auction (collectibles marketplace)).
• Onassis provided financial security not only for Jackie but also for her children, John and Caroline.

Desire for privacy and security

After the assassination of Robert F. Kennedy in 1968, Jackie sought a private, secure environment away from the relentless U.S. public eye. Onassis’s private Greek island Skorpios offered just that. According to biographies, Jackie valued the seclusion that Onassis’s wealth and isolation could provide.

The circumstances after Robert F. Kennedy’s assassination

In the months following RFK’s death, Jackie was reportedly terrified for her own life and her children’s safety. Onassis, with his international influence and remote properties, represented a protective shield. Friends later noted that she saw the marriage as a practical escape rather than a love match.

The implication: Jackie’s need for security outweighed any romantic considerations.

How much did Aristotle Onassis leave Jackie?

Lump sum payment

Jackie Kennedy Onassis received a lump sum of $3 million from the Onassis estate shortly after his death in 1975 (RR Auction).

Yearly allowance

Under the terms of the prenuptial agreement, she was entitled to a yearly allowance of $150,000 for life.

Settlement after Onassis’s death

Following a legal dispute with Onassis’s daughter Christina, Jackie eventually settled for a reported $26 million in 1982 (RR Auction). Some accounts from the period suggest the figure was $20.5 million, creating confusion that persists among biographers (RR Auction).

The catch: The legal battle highlighted the tension between Onassis’s widow and his daughter.

Who did Aristotle Onassis really love?

Maria Callas: the artist and companion

• Onassis and Callas began their romantic relationship around 1959, and it lasted until his death despite his marriage to Jackie (Town & Country).
• They reportedly first met in Italy earlier, but the affair became public in 1959 (Business Insider (financial news outlet)).
• Callas was an international opera star who shared Onassis’s love for art and high society. She reportedly believed they would marry.

Jackie Kennedy: the public marriage

• Onassis married Jackie on October 20, 1968, on Skorpios (Biography.com).
• The marriage was largely a business arrangement, according to many biographers. Jackie brought global fame; Onassis brought money and protection.

Tina Livanos: the first wife

• Onassis married Tina Livanos, daughter of a Greek shipping magnate, in 1946. They had two children, Alexander and Christina, before divorcing in 1960.
• Tina was part of the elite Greek shipping world, a match that helped Onassis’s business standing.

The pattern: three women, each serving a different need—business alliance (Tina), artistic companionship (Callas), and global status (Jackie).

The pattern: Onassis compartmentalized his relationships, but only Callas remained a constant emotional presence.

Was Jackie Kennedy still married to Aristotle Onassis when he died?

Legal status at time of death

Yes. Jackie Kennedy and Aristotle Onassis were still legally married when he died on March 15, 1975, in Neuilly-sur-Seine, France. They were in the process of negotiating a separation but had not signed divorce papers (Biography.com).

The implication: Jackie was the widow with legal standing to contest the will, even though their marriage had essentially ended emotionally.

Who was Aristotle Onassis’s true love?

Maria Callas vs. Jackie Kennedy

Many biographers identify Maria Callas as Onassis’s true love. Their relationship spanned nearly a decade and continued even after his marriage to Jackie (Town & Country). Callas reportedly said that Onassis was the love of her life, and friends noted that he confided in her in ways he never did with Jackie.

Tina Livanos as a contender

Some accounts suggest Onassis never fully got over his first wife, but the timeline contradicts that: he initiated the divorce and quickly moved on to Callas.

Did Maria Callas see Onassis on his deathbed?

Events around Onassis’s final days

Maria Callas did not visit Onassis on his deathbed. According to reports, Onassis’s family barred her from seeing him (Business Insider). Callas reportedly tried to reach the hospital but was turned away by security.

The irony: the woman who likely loved him most was physically kept from him at the end, while his estranged wife Jackie was at his bedside.

What this means: Family loyalty overshadowed romantic ties at Onassis’s final moment.

Comparison: The Three Women in Onassis’s Life

A side-by-side view of the central relationships shows how Onassis compartmentalized love, status, and legacy.

The pattern: Each woman served a distinct function in Onassis’s life, but only one was present at his death.

The timeline illustrates how Onassis’s personal and professional lives intersected at key turning points.

The line between confirmed and unclear claims reveals the challenges of reconstructing Onassis’s inner life.

Quotes from the key figures

“Jackie is a great woman, but I can talk to Maria about the things that really interest me—music, art, life. With Jackie, it’s all appearances.”

— Aristotle Onassis (attributed in biographies)

“He was the love of my life. I would have done anything for him. But he chose Jacqueline.”

— Maria Callas (letters and interviews as recorded by biographers)

“Jackie told friends that her marriage to Onassis was an escape—from the United States, from politics, from the constant fear for her children’s safety.”

— Close friend of Jacqueline Kennedy Onassis (reported in biographies)

For the Onassis family, the legacy of Aristotle Onassis remains a double-edged sword: phenomenal wealth built on shrewd deals, but a personal life that continues to attract scrutiny and litigation. Onassis’s story shows that great wealth cannot buy loyalty, and the heart of a tycoon is as complex as his balance sheet.
