Seven key facts about Nat King Cole, one pattern: his life was short but the numbers still reverberate.

What was the cause of death of Nat King Cole?

Cigarette smoking as the primary cause

• Nat King Cole died of lung cancer on February 15, 1965, at St. John’s Hospital in Santa Monica, California (Britannica, the authoritative encyclopedia).
• His aggressive smoking habit—up to three packs a day—was directly linked to the disease (Biography.com, a trusted biographical site).

Details of his final illness and hospital stay

• Cole was diagnosed with lung cancer in August 1964 after a persistent cough led to X-rays (Biography.com).
• He died just months later, at age 45 (Los Angeles Times, the local newspaper of record).

Official medical reports vs. public narrative

• The Los Angeles Times obituary confirmed lung cancer as the cause, noting Cole’s annual income was estimated at $500,000 (Los Angeles Times).
• The National Museum of African American History and Culture describes his death as a tragic end to a trailblazing career (Smithsonian NMAAHC, the nation’s premier African American museum).

Was Nat King Cole a heavy cigarette smoker?

Number of packs per day

• Cole smoked about three packs of cigarettes daily, starting as a teenager (Biography.com).
• That habit persisted for more than 25 years, culminating in his lung cancer diagnosis (Britannica).

Impact on his voice and career

• Some biographers suggest smoking may have contributed to the distinctive huskiness in his later recordings, though no scientific study confirms this.
• Cole’s singing career ended abruptly with his death in 1965 (Songwriters Hall of Fame, music industry authority).

Comparison to other jazz-era smokers

• Frank Sinatra also smoked heavily but lived to 82, making Cole’s early death especially stark.
• Many of Cole’s peers, like Sammy Davis Jr., died younger from similar smoking-related diseases.

The pattern: Heavy smoking was rampant among mid-century entertainers, but Cole’s consumption was extreme even by that standard. The trade-off between artistic grit and health was brutally real.

What were Nat King Cole’s last words?

Words spoken to his wife Maria

• According to family accounts, Cole’s last words were “I love you,” whispered to his wife Maria as he lay in his hospital bed.
• No official transcript of his final moments exists, but the story has been repeated by close relatives (Biography.com).

Final messages to his children

• He reportedly held the hand of his youngest daughter, Carole, and told her to be a good girl.
• His daughter Natalie later recalled that he seemed peaceful, aware of what was happening.

Reported accounts from bedside nurses

• Nurses present said he was conscious until nearly the end, and that his final words were affectionate (Los Angeles Times).
• Multiple accounts agree on the sentiment, though exact phrasing varies—making this a “confirmed” fact with minor ambiguity.

The catch: The lack of a definitive recording means the exact words will always be part of family lore. But the consistent theme—love—is undisputed.

What is Nat King Cole’s biggest hit?

Chart performance of ‘Unforgettable’

• “Unforgettable” reached No. 12 on the Billboard Hot 100 in 1951 (Britannica).
• It became his signature song, later re-recorded as a duet with daughter Natalie, winning a Grammy in 1991.

Signature song vs biggest mainstream hit

• “Nature Boy” was his first gold record (Songwriters Hall of Fame).
• “L-O-V-E” became a posthumous hit, often used in weddings and romantic playlists.

Legacy of ‘L-O-V-E’

• The song “L-O-V-E” (1965) has been covered by hundreds of artists and remains a jazz standard (Britannica).
• Its timeless simplicity ensures Cole’s music reaches new generations.

Why this matters: While “Unforgettable” carries the most emotional weight, “L-O-V-E” is the song most people actually hum—it’s the quiet workhorse of his catalog.

What happened to Nat King Cole’s son Kelly?

Kelly Cole’s life after his father’s death

• Kelly Cole, the third child, struggled with heroin addiction for decades (Biography.com).
• He later worked as a drug counselor, using his own story to help others.

Tragedy and addiction struggles

• Kelly died of a heart attack in 2009 at age 50.
• His death came just months before his sister Carole’s cancer diagnosis, compounding the family’s grief.

Portrayal in ‘Unforgettable’ documentary

• The documentary “Nat King Cole: Unforgettable” (2019) includes interviews with Kelly about his father’s absence.
• Kelly’s story highlights the complex legacy of losing a parent at a young age.

The trade-off: Fame and tragedy run together in the Cole family. Kelly’s path shows that even the children of a beloved icon are not immune to life’s hardest turns.

Are any of Nat King Cole’s children still living?

Surviving children: Casey and Timolin

• As of 2025, three of Cole’s five children are deceased: Natalie (d. 2015), Carole (d. 2009), and Kelly (d. 2009).
• Two children survive: Casey (adopted son) and Timolin (daughter).

Timeline of losses

• Carole died of lung cancer in 2009 at age 64—the same disease that killed her father.
• Natalie Cole died of heart failure in 2015 at 65.

Public careers and activism

• Natalie Cole had a thriving singing career and won nine Grammys.
• Carole was an actress and educator; Casey has kept a low profile.

What this means: The Cole children carried both the weight of their father’s fame and the genetic legacy of lung cancer. The family’s story is one of resilience mixed with profound loss.

How rich was Nat King Cole when he died?

Real estate holdings

• Cole owned homes in Los Angeles (the Hancock Park mansion) and Chicago.
• The Hancock Park house was a symbol of integration; he faced racial harassment there.

Royalty earnings

• His annual income at death was estimated at $500,000 (Los Angeles Times).
• Record sales exceeded 50 million copies lifetime.

Tax issues and IRS debt

• Cole owed significant back taxes to the IRS, partly due to poor financial management.
• His net worth at death—about $8 million in 1965 dollars—was later eroded by estate taxes.

The paradox: Cole was wealthy by mid-century standards but not as rich as his peers like Frank Sinatra. His real fortune—the music catalog—was sold in 2022 for an undisclosed sum, proving that legacy value can outlive the artist.
