Mark Harmon, born as Thomas Mark Harmon on September 2, 1951, in Burbank, California, is an American actor who has made significant contributions to the entertainment industry over several decades. He was born into a family with deep roots in the Hollywood industry: his mother, Elyse Knox, was an actress and his father, Tom Harmon, was an acclaimed football player and broadcaster. Despite this, Harmon initially focused on a career in sports, following in his father's footsteps and achieving success as a quarterback at UCLA during the early 1970s.

His breakthrough role came in the 1980s when he starred in the medical drama St. Elsewhere as Dr. Robert Caldwell. However, it's his portrayal of Leroy Jethro Gibbs in the hit CBS series NCIS that has earned him widespread recognition and acclaim. His performance in this role has led to numerous award nominations and wins, confirming his reputation as one of television's most reliable and admired actors. Despite the fame and recognition, Harmon has always valued his private life, maintaining a low-key profile away from the limelight. He married actress Pam Dawber in 1987, and they have two sons together. Known for his dedication, work ethic, and ability to balance a successful acting career with a grounded personal life, Harmon's story is a testament to his versatility and commitment. His enduring presence in the entertainment industry is a tribute to his talent and professionalism, making him an iconic figure in television history.
