Age
David Keith McCallum was born on 19 September 1933 in Glasgow, Scotland
David Keith McCallum was born on 19 September 1933 in Glasgow, the younger of two sons of violinist David Fotheringham McCallum and cellist Dorothy McCallum (née Dorman). When he was three, the family moved to London so his father could lead the London Philharmonic Orchestra. Early in World War II, he was evacuated back to Scotland and lived with his mother at Gartocharn near Loch Lomond.
McCallum earned a scholarship to University College School, a boys’ school in Hampstead, London. Encouraged by his parents to pursue music, he played the oboe. At 13, he began voicing roles for the BBC Radio Repertory Company. He also took part in local amateur drama and, at 17, played Oberon in an outdoor production of A Midsummer Night’s Dream with the Play and Pageant Union. After leaving school at 18, he was conscripted for National Service and joined the British Army’s 3rd Battalion, Middlesex Regiment, which was assigned to the Royal West African Frontier Force. He was promoted to lieutenant in March 1954. After his army service, he attended the Royal Academy of Dramatic Art in London, where Joan Collins was one of his classmates.
NCIS
In 2003, McCallum began playing Dr. Donald “Ducky” Mallard, chief medical examiner, on the CBS series NCIS, first appearing in the original backdoor pilot on JAG. Ducky became one of the show’s most popular characters. In Season 2, Episode 13, “The Meat Puzzle,” NCIS Special Agent Caitlin Todd (Sasha Alexander) asks Special Agent Leroy Jethro Gibbs (Mark Harmon), “What did Ducky look like when he was younger?” Gibbs replies, “Illya Kuryakin”. To prepare for the role, McCallum became knowledgeable in forensics, attending medical examiner conventions. According to Donald P. Bellisario, McCallum’s expertise grew so extensive that he considered appointing him as a technical adviser to the show.
On 19 May 2005, McCallum spoke at the 21st Annual James Earl Ash Lecture at the Armed Forces Institute of Pathology, an event honoring America’s service members. His talk, “Reel to Real Forensics,” with Cmdr. Craig T. Mallak, compared the real work of the Armed Forces Medical Examiner staff to the fictional investigators on NCIS.
In April 2012, McCallum agreed to a two-year contract extension with CBS-TV, allowing him to stay on NCIS past his eightieth birthday. He signed another two-year contract in May 2014,[24] then extended again in 2016. Starting in 2017, he worked a limited schedule and renewed his contract each season.
After Mark Harmon departed NCIS in fall 2021 (Season 19), McCallum remained the last original cast member until his death in 2023.
Writing
In 2016, McCallum published the crime novel Once a Crooked Man, set in New York and London, about a young actor who attempts to prevent a murder. At the time, he stated he was working on a second novel.
Personal life
McCallum married actress Jill Ireland in London on 11 May 1957. They met while working on the film Hell Drivers. The couple separated for about two years before their marriage ended legally in February 1967. They had three sons, including Valentine.
On 16 September 1967, McCallum married Katherine Carpenter, a former fashion model and interior designer, in Valley Stream, New York. They met at a Glamour magazine photo shoot in 1965 and were together for 58 years. The couple had a son and a daughter. McCallum and his wife supported charitable organisations benefiting the United States Marine Corps. Katherine’s father served in the Battle of Iwo Jima, and her brother was killed in the Vietnam War. On 27 August 1999, McCallum became a naturalised United States citizen. He had six grandchildren and was friends with Tibor Rubin.
Death
McCallum died of natural causes at age 90 on 25 September 2023 at NewYork-Presbyterian Hospital in New York City. On the same day, CBS aired the NCIS 20th anniversary mini-marathon. His remains were cremated.
