“NCIS” is a television series that follows a fictional team of special agents, their work and their personal lives. The show combines elements of military dramas and police procedural genres, making for an extremely impactful show that has gone on to become a fan favorite and phenomenon. “NCIS” first aired back in September 2003 and has since gone into broadcast syndication as one of the longest-running scripted non-animated primetime TV series.

With such an impactful show, it’s no surprise that many of its main actors have gone on to have fulfilling careers and have garnered plenty of media attention. Some of the main stars over the years have included Mark HarmonPauley PerretteCote de Pablo, David McCallum and more.

McCallum was born on Sept. 19, 1933, in Maryhill, Glasgow. He is best known for his role as Dr. Donald “Ducky” Mallard on NCIS. The actor is also recognized for his roles in “The Great Escape” and “The Man from U.N.C.L.E.”

During his childhood, McCallum was encouraged to pursue a career in music, especially since his father – David McCallum Sr. – was an orchestral violinist. McCallum had learned how to play the oboe but eventually switched over to acting and began pursuing drama when he was in his late teens. He even went on to attend the Royal Academy of Dramatic Art in London, England and was classmates with Joan Collins.

While McCallum has since led a very successful career, he has also found great success in finding love. Although his first marriage ended after ten years, the actor went on to find love again with a woman named Katherine Carpenter. Read on to find out more about their love story.

Ever since he was a child, McCallum has shown to have a great love for the arts. He grew up surrounded by culture and creativity, and it surely has seeped its way into McCallum’s work today.

According to The Scotsman, he is the second son of cellist Dorothy Dorman and orchestra leader David McCallum Sr. The latter ended up leading the London Philharmonic. “I was born by the Botanic Gardens, but 65 Clouston Street is where my grandfather lived, and most of the time I’d stay there,” McCallum explained. “Father, way back in the 1930s, was with the Scottish Orchestra, and so he would be working at the BBC there.”

He continued, “We moved to Hampstead in 1936, when Father became leader of the London Philharmonic. At the end of 1939 or the beginning of 1940, I was evacuated.” Afterward, the family went to stay with McCallum’s aunt for several years before finding a house to live in.

McCallum certainly experienced a lot throughout his childhood, but it’s evident that he was always surrounded by creative people. While the star first started out with an appreciation for music, he really began pursuing his passion for acting when he was a teenager. However, he had first begun acting during his childhood.

“I played The Little Prince in Shakespeare’s ‘King John,’ at one of those local things where people do skits and songs,” McCallum said. “Mine was the little prince having his eyes put out by this terrible man, and I acted it, evidently, very well, because I got a standing ovation. I wasn’t more than 8.”
