Aristotle Onassis built one of the largest private shipping fortunes in history, yet the two women who married him lived lives marked by tragedy that still provoke questions decades later. One became one of the most photographed women on Earth. The other died suddenly under circumstances eerily similar to her own sister’s earlier death. Born on January 20th, 1906, in Smyrna, then part of the Ottoman Empire and now known as Izmir in modern Turkey, Onassis grew up in a prosperous Greek merchant family.
In 1922, a devastating fire destroyed much of the city amid a military conflict, forcing the Onassis family along with hundreds of thousands of other Greeks to flee. By 1923, still a teenager, Aristotle arrived in Argentina with almost no money and a huge amount of ambition. In Buenos Aires he built his first fortune trading tobacco, reinvesting nearly everything he earned. By the 1930s he had turned to shipping, buying his first freighters at rock-bottom prices during the Great Depression.
That gamble eventually produced one of the largest privately owned shipping fleets in the world. In 1946, Onassis married Athina Mary Livanos, known as Tina, the daughter of Greek shipping magnate Stavros Livanos. The marriage united two of Greece’s most powerful shipping fortunes. Tina was 17 at the time of the wedding; Onassis was 40.
The ceremony took place on December 28th, 1946, in New York City. The couple had two children: Alexander, born in 1948, and Christina, born in 1950. On the surface, their marriage looked like a glamorous, powerful partnership, but cracks were already forming beneath the surface. In 1957, Onassis met celebrated opera singer Maria Callas.
Two years later, he invited Callas and her husband aboard his private yacht, the Christina, for a Mediterranean cruise that included Winston Churchill among the guests. During that voyage, their friendship became an affair. Tina eventually discovered what was happening, and the couple divorced in 1960 after a 14-year marriage. Onassis’s relationship with Callas continued for years afterward, but it would not define the next major chapter of his life.
That belonged to a woman still known to the world as the former first lady of the United States. Jacqueline Bouvier Kennedy had married then-Senator John F. Kennedy in 1953 and became a global icon after his election to the presidency in 1960. In the fall of 1963, she lost her newborn son Patrick days after his premature birth.
Onassis, who had already developed a friendship with the Kennedys, offered comfort and even invited her aboard his yacht to help her recover. Just months later, President Kennedy was assassinated in Dallas, Texas, in November 1963, throwing Jacqueline into a period of national mourning watched by the entire world. In the years that followed, Onassis remained a steady presence in her life, offering privacy and security she found nowhere else. Their friendship deepened, even as members of the Kennedy family reportedly expressed serious reservations.
Robert Kennedy in particular was said to hold deep concerns about the relationship. On October 20th, 1968, Jacqueline Kennedy married Aristotle Onassis in a private ceremony on Skorpios, his privately owned island in the Ionian Sea. The wedding shocked American society and much of the world, transforming the widow of an assassinated president into the wife of a controversial businessman 23 years her senior. She soon earned the nickname “Jackie O,” a moniker that would follow her for the rest of her life.
Behind the scenes, the marriage was far more complicated than the public imagined. Onassis’s relationship with Callas reportedly never fully ended. Jacqueline, by most accounts, was aware of the ongoing connection but chose to focus on her own independence and privacy, splitting her time between Greece, Paris, and New York. Before the wedding, Onassis had also insisted on a carefully negotiated prenuptial agreement.
While Onassis navigated his new marriage, Tina had built a new life. In 1961, she married John Spencer-Churchill, known as Sunny, who later became the 11th Duke of Marlborough, giving Tina the title of Marchioness of Blandford. That marriage ended in divorce in 1971. That same year, in October 1971, Tina made a decision that stunned nearly everyone who knew the intertwined history of these shipping families.
She married Stavros Niarchos, the same shipping rival who had once been part of a powerful three-family alliance with her father and her first husband. What made the marriage even more striking was that Niarchos was the widower of Tina’s own older sister, Eugenia, who had died suddenly in 1970 under circumstances that had already generated considerable speculation. The Livanos family reportedly gave their blessing to the union, but Tina’s first husband and her own son, Alexander, both openly opposed the marriage. In January 1973, tragedy struck the Onassis family in the most painful way imaginable.
Alexander, the only son of Aristotle and Tina, and the young man widely expected to inherit his father’s shipping empire, was involved in a catastrophic plane crash at Athens airport. He had been practicing takeoffs and landings in a small aircraft when the crash occurred. He died on January 23rd, 1973, at just 24 years old, never having regained consciousness. The loss devastated both parents.
Onassis reportedly became consumed with the idea that the crash had not been a simple accident, pursuing private investigations for years, though nothing ever emerged to substantiate any theory beyond the official finding of an accident. For Tina, the grief compounded years of accumulated loss and upheaval. On October 10th, 1974, less than two years after losing her son, Tina Onassis Niarchos was found dead in the bedroom of the Paris mansion she shared with her husband, Stavros Niarchos. She was 45 years old.
Niarchos had reportedly been asleep in the next room and remained unaware of what had happened until the following morning. An autopsy determined that Tina had died from pulmonary edema, a buildup of fluid in the lungs, which investigators concluded was closely associated with a dependency on barbiturates. Those who knew her in her final months suggested that the accumulated weight of grief from Alexander’s death, layered on top of decades of personal upheaval, had left her increasingly reliant on medication. The circumstances surrounding her death generated intense speculation because of the eerie parallel to her own sister’s death just a few years earlier.
Eugenia, Niarchos’s previous wife and Tina’s older sister, had also died suddenly and under circumstances that were never fully or publicly clarified. Both women had died in the same household, married to the same man, within a span of a few years. No formal criminal findings were ever brought against Niarchos in connection with either death. Tina was laid to rest at the Bois de Vaux Cemetery in Lausanne, Switzerland.
The years following Alexander’s death and Tina’s passing took a severe toll on Onassis’s health. He had been diagnosed with myasthenia gravis, a chronic autoimmune disorder that causes progressive muscle weakness, and the accumulated stress appeared to accelerate his physical decline. His eyesight deteriorated noticeably, and he was seen far less frequently in public. On March 15th, 1975, Aristotle Onassis died in Neuilly-sur-Seine, near Paris, France, at the age of 69.
His will left the bulk of his fortune to his surviving daughter, Christina. Jacqueline received a settlement reported at between $20 and $26 million, a substantial sum but far smaller than the vast majority of his estate. Onassis was laid to rest on his private island of Skorpios alongside his son Alexander. Following Onassis’s death, Jacqueline returned to New York City and built an entirely different life.
She began a career in book publishing, first as a consulting editor at Viking Press and later at Doubleday, where she rose to senior editor. She also became deeply involved in historic preservation efforts in New York, notably playing a significant role in the campaign to save Grand Central Terminal from demolition during the 1970s. She largely avoided remarrying, instead maintaining a private relationship with Maurice Tempelsman, a Belgian-born diamond merchant who became her close companion and financial adviser. Together they lived a quiet life that included regular walks through Central Park and summers at her Martha’s Vineyard estate.
In early 1994, Jacqueline was diagnosed with a serious form of cancer affecting her lymphatic system. Despite treatment, the disease proved impossible to overcome. On May 19th, 1994, Jacqueline Kennedy Onassis died in her New York City apartment at the age of 64, with Tempelsman by her side. She was laid to rest at Arlington National Cemetery alongside President Kennedy and their two children who had died in infancy.
The contrast between Onassis’s two wives remains difficult to ignore. Tina Livanos, the teenage bride who helped unite two of Greece’s most powerful shipping dynasties, spent her adult life moving through marriage after marriage and tragedy after tragedy, dying at just 45 under deeply unsettling circumstances that echoed her sister’s earlier death. Jacqueline Kennedy, by contrast, rebuilt an independent identity after Onassis’s death, living nearly two decades longer and carving out a career and a life that felt recognizably her own. Both women, in their own strikingly different ways, carried the weight of having been married to one of the most powerful and complicated men of the 20th century.
Decades later, their stories continue to fascinate new generations, because behind the glamorous headlines sat genuine hardship and heartbreak.
