When Jacqueline Kennedy stepped back into the spotlight in 1968, the world gasped. The elegant widow of President John F. Kennedy had just married one of the richest men alive — Greek shipping tycoon Aristotle Onassis. Overnight, “Jackie O” was born, and America’s most beloved First Lady became the subject of endless headlines, whispers, and fascination.
Jackie Kennedy second husband wasn’t a politician or a movie star. He was a self-made billionaire who offered her something priceless after two assassinations shattered her world: security, privacy, and a fresh start. Their union lasted just six and a half years, yet it remains one of the most talked-about romances in modern history.
If you’ve ever wondered about Jackie Kennedy second husband, this is the real story — glamorous, complicated, and surprisingly human.

Who Was Aristotle Onassis?
Aristotle Socrates Onassis wasn’t born into wealth. He built an empire from scratch.
Born on January 20, 1906, in Smyrna (now Izmir, Turkey), he fled to Argentina as a teenager after the Greco-Turkish War. By his twenties, he had already made his first million in tobacco. But ships became his obsession. He pioneered supertankers and created the largest private shipping fleet in the world, turning him into one of the wealthiest men of the 20th century.
Here’s what made him unforgettable:
- He owned the legendary yacht Christina, once the most luxurious private vessel afloat, complete with a swimming pool that doubled as a dance floor.
- His private island, Skorpios, served as a secluded paradise for royalty, celebrities, and secret meetings.
- He had a sharp business mind and an even sharper social circle — from Winston Churchill to Maria Callas.
By the time Jackie entered his life, Onassis was 62, worldly, and larger than life. He wasn’t polished like the Kennedys, but his confidence and resources were magnetic.
How Jackie Kennedy Met Her Second Husband
Their paths first crossed in the 1950s through Jackie’s sister, Lee Radziwill. Onassis was already a friend of the Bouvier family, and the two shared occasional dinners and yacht cruises.
But real closeness came after tragedy struck — twice.
After JFK’s assassination in 1963, Jackie felt trapped by public grief and constant media attention. Then, in 1968, her brother-in-law Robert Kennedy was also killed. Terrified for her children’s safety, Jackie turned to the one man who could shield them: Aristotle Onassis.
He offered what no one else could — a fortress of privacy, private jets, and an escape from American scrutiny. Friends say the marriage was partly practical: Jackie sought protection and financial freedom; Onassis wanted the ultimate status symbol — America’s former First Lady on his arm.
The Lavish Wedding and Married Life
On October 20, 1968, Jackie Kennedy became Jacqueline Kennedy Onassis in a quiet ceremony on Skorpios. No grand cathedral, no thousands of guests — just close family, tight security, and a simple Greek Orthodox service.
The honeymoon phase sparkled with jet-set glamour. They cruised the Mediterranean, dined in Paris, and entertained stars. Jackie finally had breathing room to raise Caroline and John Jr. away from the spotlight.
Yet cracks soon appeared:
- They often lived on opposite sides of the Atlantic — Jackie in New York, Onassis in Europe.
- Rumors swirled about Onassis’s long-standing relationship with opera legend Maria Callas.
- Jackie reportedly knew about the affair but chose to look the other way, focusing on her children and new career as a book editor.
Despite the distance, there was genuine fondness. Onassis called her “the only woman who could keep up with me,” and Jackie valued his strength and generosity.
Challenges, Heartbreak, and a Quiet Farewell
By the early 1970s, their marriage felt more like a partnership than a passion. Onassis faced business troubles and the devastating loss of his son Alexander in a 1973 plane crash. Jackie stood by him, but the emotional toll showed.
They never divorced. When Aristotle Onassis died on March 15, 1975, in Paris from respiratory failure, Jackie was at his side. She inherited an estimated $20–26 million and returned to New York, where she built a respected career at Doubleday and protected her children’s privacy fiercely.
