Eight key facts about Jacqueline Kennedy Onassis, verified across primary sources.

What was Jackie Onassis’ cause of death?

Diagnosis and illness timeline

• December 1993: Diagnosed with non-Hodgkin lymphoma (National Archives Foundation)
• January 1994: Publicly announced diagnosis; initial prognosis said to be good (National Archives Foundation)
• May 1994: Cancer pronounced terminal (National Archives Foundation)
• May 19, 1994: Died in her sleep at age 64 in her New York City apartment (TIME)

Circumstances of her passing

Jacqueline Kennedy Onassis spent her final weeks at home, surrounded by family. She continued to work at Doubleday as a senior editor even while undergoing chemotherapy (National Archives Foundation). Her death was peaceful — she drifted off and never woke up, according to family statements.

Public announcement and reaction

President Bill Clinton delivered a eulogy at her graveside service at Arlington National Cemetery (National Archives Foundation). She was laid to rest next to President John F. Kennedy, their son Patrick, and their stillborn daughter Arabella (National Archives Foundation).

The catch: Despite the public outpouring, Jackie had carefully avoided a spectacle. Her obituary in the New York Times noted that she had requested a small, private funeral — the same instinct for privacy that defined her post-White House years.

Who was the love of Jacqueline Kennedy’s life?

JFK’s role in her life

John F. Kennedy is widely regarded as the great love of her life (JFK Library). She coined the term “Camelot” to describe his presidency, immortalizing their time together as a golden age.

Aristotle Onassis relationship

Her marriage to Aristotle Onassis in 1968 was more pragmatic. After JFK’s assassination, she sought protection and financial security for herself and her children. Onassis, a Greek shipping magnate (JFK Library), provided that — but the relationship was marked by loneliness. Onassis himself said of her: “She is a very great lady, but a very lonely one.”

Later companions and private statements

After Onassis died in 1975 (JFK Library), she never remarried. No definitive public statement from Jackie ever named one man as her “true love” — the question remains unsettled in popular imagination.

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

Timeline of marriage and separation

• 1968: Married Aristotle Onassis (JFK Library)
• Early 1970s: The couple began living apart — Jackie spent most of her time in New York, Onassis in Greece
• March 15, 1975: Aristotle Onassis died in Paris (JFK Library)

Legal and marital status at time of death

They were still legally married at the time of his death. Although separated, neither had filed for divorce. Jackie attended his funeral in Greece as his widow.

The implication: The legal tie meant she inherited a portion of his estate, but also endured the strain of a public marriage that had long been private misery.

What was the age gap between Jackie and JFK?

Birth dates and difference

• Jacqueline Bouvier: born July 28, 1929 (White House Historical Association)
• John F. Kennedy: born May 29, 1917 (White House Historical Association)
• Age gap: 12 years, 2 months
• At marriage on September 12, 1953: JFK was 36, Jackie was 24 (JFK Library)

Comparison to gap with Onassis

Aristotle Onassis was born in 1906 — 23 years older than Jackie. The gap was larger, and the power dynamic different. Both marriages followed a pattern of younger wife, older, powerful husband.

Was Jackie ever unfaithful to JFK during their marriage?

Allegations and rumors

Rumors have circulated for decades linking Jackie to Italian industrialist Gianni Agnelli and other men. No credible documentary evidence has ever surfaced to confirm an affair (JFK Library). Biographers note the lack of proof and emphasize that JFK’s own infidelities are well-documented, but Jackie’s fidelity remains a matter of speculation.

Known relationships and denials

Friends and aides have consistently denied that Jackie was unfaithful. The lack of any firsthand account or personal confession makes the claim unverifiable.

Catch: Without evidence, the question says more about public fascination with her private life than about any actual behavior. The burden of proof lies with the accusers, and so far it hasn’t been met.
