Jacqueline Kennedy Onassis: Biography, Death, and Net Worth

Kennedy, she made a choice that shocked the world: marrying Greek shipping magnate Aristotle Onassis. This article explores the private decisions, financial settlements, and personal tragedies that shaped her legacy, drawing on verified records from the JFK Library, White House archives, and Britannica.

Born: July 28, 1929 · Died: May 19, 1994 · First Lady: 1961 – 1963 · Spouses: John F. Kennedy (m. 1953–1963), Aristotle Onassis (m. 1968–1975) · Children: Caroline, John Jr., Patrick (died infancy)

Seven key facts, one pattern: Jacqueline Kennedy Onassis reinvented herself multiple times — from debutante to First Lady, to private citizen, to editor. The table below captures the essential biographical markers.

Was Jackie Kennedy still married to Onassis when he died?

Jacqueline Kennedy married Aristotle Onassis on October 20, 1968, on his private Greek island Skorpios (EBSCO Research Starters). Aristotle Onassis died on March 15, 1975, at the age of 69 (White House archives). Jackie was still legally married to him at the time of his death. The marriage lasted nearly seven years, though it was strained by the death of Onassis’s son Alexander in 1973. The implication: Jackie remained Onassis’s widow, which entitled her to a substantial settlement from his estate.

What was Jackie’s cause of death?

Jacqueline Kennedy Onassis died on May 19, 1994, at her home in New York City. Multiple sources identify her cause of death as cancer (Encyclopedia.com). A secondary source describes her death more specifically as occurring after lymphoma (Encyclopedia.com). She was diagnosed in early 1994 and underwent treatment, but the disease progressed rapidly. Her death was widely reported as peaceful. The pattern: Even in her final illness, Jackie controlled the narrative — few details were released to the press.

What were Jackie’s last words to JFK?

On November 22, 1963, as President Kennedy was shot in Dallas, Jackie Kennedy’s reported last words to him were: “Oh, Jack! Oh, Jack!” (Encyclopedia.com). This account comes from eyewitnesses and later interviews. No official transcript exists, but the phrase is widely accepted. The trade-off: The absence of a recorded confirmation means the exact words remain a matter of historical memory, not hard evidence.

Why did Jackie Kennedy marry Onassis?

After JFK’s assassination, Jackie sought privacy and protection for her children. Aristotle Onassis was a wealthy Greek shipping magnate who could provide security and a private lifestyle (EBSCO Research Starters). The marriage in 1968 surprised many, but she stated it was for personal reasons. Onassis was 23 years older than Jackie (White House archives). The catch: The marriage gave her financial independence and a shield from the relentless press, but it also subjected her to criticism for abandoning the Kennedy image.

How much money did Jackie get from Onassis when he died?

Upon Aristotle Onassis’s death in 1975, Jackie received a settlement variously estimated at $20 million to $26 million (Britannica). Wikipedia reports that her share of the Onassis estate was reported as $10 million, with other sources citing $26 million (Wikipedia). She also inherited the use of the Onassis yacht, Christina O, for a period. The exact amount was part of a legal agreement with Onassis’s daughter, Christina. Adjusted for inflation, $20 million in 1975 is equivalent to roughly $100 million today. The implication: Jackie’s financial future was secured, but the settlement required her to waive any further claims to the Onassis fortune.
