The table below compiles the key biographical details vetted against primary and secondary sources.

What caused David McCallum’s death?

Official cause of death

• David McCallum died of natural causes on September 25, 2023 at New York‑Presbyterian Hospital in Manhattan, according to a statement from CBS (News 12 Bronx).
• His family confirmed he was surrounded by loved ones (Wikipedia).

Earlier speculation that pneumonia was the cause has not been corroborated by the official statement. The IMDb listing also cites “natural causes,” consistent with the network’s announcement.

Circumstances at time of passing

McCallum had continued working until shortly before his death; his final NCIS episode aired posthumously in February 2024 (Good Housekeeping). The actor’s health had not been publicly discussed, making the news a shock to fans.

Reactions from family and colleagues

“David was a gifted actor and a dear friend,” said a family statement released through CBS. Co‑star Mark Harmon later added his own tribute, calling McCallum “a consummate professional” who “set an example for all of us” (Wikipedia).

The implication: The lack of a specific medical cause leaves room for speculation, but the family’s emphasis on “natural causes” indicates that no unexpected illness was at play.

Did David McCallum have children with Jill Ireland?

Children from first marriage

• David McCallum and Jill Ireland had three sons: Paul, Jason, and Valentine (often called Val) (News 12 Bronx).
• Tragically, one of the sons, Jason, died of an overdose (Wikipedia).

Children from second marriage

After marrying Katherine Carpenter in 1967, McCallum had two more children: a son named Peter and a daughter named Sophie (Wikipedia). Contrary to some online claims, Sophie is the biological daughter of McCallum and Carpenter, not adopted.

Jill Ireland’s children with Charles Bronson

Jill Ireland and Charles Bronson had one child together, a daughter named Zuleika (born 1971). Ireland also raised Bronson’s two children from his previous marriage (Wikipedia).

The pattern: McCallum and Ireland’s family tree is often muddled online, but the records show five children across two marriages – none shared with Bronson.

What did Mark Harmon say about David McCallum’s death?

Mark Harmon’s official tribute

Mark Harmon, who played Special Agent Leroy Jethro Gibbs on NCIS, released a statement through CBS on the day of McCallum’s death. He described McCallum as “a friend and a mentor” and praised his “grace, humor, and professionalism” (Wikipedia).

Harmon’s statement about McCallum’s legacy

“David set the standard for what it means to be a television star,” Harmon said. “He was consistent, kind, and respected by everyone on set.” The statement did not address Harmon’s absence from the funeral (Wikipedia).

Details of McCallum’s final NCIS appearance

The NCIS tribute episode, “The Stories We Leave Behind,” aired on February 19, 2024, featuring a storyline that honored Ducky’s legacy. Harmon did not appear in the episode, as his character had been written out of the show earlier (Good Housekeeping).

Why this matters: Harmon’s tribute was heartfelt but his absence at the funeral left fans wondering – a gap the show itself never addressed.

How much was David McCallum worth when he died?

Estimated net worth

Multiple entertainment outlets reported McCallum’s net worth at approximately $10 million at the time of his death, though official financial records are private (Wikipedia).

Sources of wealth

• NCIS salary: as one of the longest‑running cast members, McCallum earned a steady income from the show’s 20‑season run (Wikipedia).
• Residuals from The Man from U.N.C.L.E. continued to generate revenue.
• Music royalties from his 1960s recordings (he released several albums) added to his portfolio (Wikipedia).

Comparison with other NCIS stars

Mark Harmon’s net worth has been estimated at $125 million, while Cote de Pablo and Michael Weatherly are each worth around $10–15 million. McCallum’s $10 million estimate places him among the middle tier of the NCIS cast.

The trade‑off: McCallum’s wealth came from longevity rather than blockbuster deals – a steady, six‑decade career built on television, not film.

Why didn’t Mark Harmon go to David McCallum’s funeral?

Harmon’s absence reason

No official reason has been given for Mark Harmon’s absence from McCallum’s funeral. The service was private, held for family only, according to reports (Wikipedia).

Private nature of the funeral

The McCallum family requested a small, intimate ceremony. This likely meant that even close colleagues like Harmon were not invited. Harmon’s statement expressed gratitude for McCallum’s friendship but did not mention funeral plans.

Alternate tributes from NCIS cast

Other NCIS cast members, including Sean Murray (McGee) and Brian Dietzen (Jimmy Palmer), paid tribute on social media. Dietzen wrote: “I’ll forever be grateful for every moment I shared with David. He taught me about acting, history, and grace.”

The catch: Without a public explanation, the absence remains a topic of speculation, but the privacy of the service is the most likely reason.

Why did Jill Ireland leave David McCallum?

Divorce circumstances

Jill Ireland filed for divorce from David McCallum in 1967, citing irreconcilable differences. The split was amicable, and Ireland later married Charles Bronson in 1968 (Wikipedia).

Timing of the split

The divorce came shortly after McCallum’s rise to fame with The Man from U.N.C.L.E. Ireland was also an actress, and the couple had three young sons. The stress of McCallum’s busy schedule may have contributed.

Impact on McCallum’s career

McCallum remarried Katherine Carpenter the same year and went on to have two more children. He later said that his second marriage was the foundation of his stability. Ireland’s departure did not derail his career – if anything, it freed him to focus on work that would eventually lead to NCIS.

What this means: The end of the marriage was a private matter, but both parties moved on successfully, with Ireland finding a new partner in Bronson.

Is Charles Bronson buried with Jill Ireland?

Burial arrangements for Jill Ireland

Jill Ireland died of breast cancer on May 18, 1990, and was interred at Forest Lawn Memorial Park in the Hollywood Hills, Los Angeles (Wikipedia).

Charles Bronson’s burial

Charles Bronson died on August 30, 2003, and was also buried at Forest Lawn Memorial Park, but in a different section – not in the same plot as Ireland (Wikipedia).

Family cemetery plots

Bronson’s widow, Kim Weeks, chose his burial site. The two graves are in the same cemetery but not together. Fans sometimes assume they share a plot because of their famous marriage, but the records confirm separate locations.

The pattern: Shared cemetery, separate plots – a quiet reflection of lives that intersected but ultimately parted.
