Biography

Pre-Series

Born in Scotland to Victoria Mallard and Joseph Mallard, presumably in September 1933, Ducky grew up in Scotland.

His parents presumably later divorced with Joseph remarrying a woman named Lorraine with that marriage producing a son, Nicholas Mallard who is Ducky's half-brother.

He was educated at Eton College, and subsequently graduated from University of Edinburgh's Medical School.

He also attended King's College, Cambridge for a year before leaving to go to medical school he started to study English Language and History.

Ducky also worked with several other other organizations including the British police and also served in the military during the Vietnam War although whether he served in the American military is unknown. Ducky also served as a Captain in the Royal Army Medical Corps (RAMC), a unit in the British Army.

In 1980, Ducky worked in a refugee camp in Afghanistan and while there, he became acquainted with Polish born CIA interrogator, Marcin Jerek who was known locally as "Mr. Pain."

As a result of this acquaintance Ducky was later mistakenly charged with war crimes for violating Article Four of the 1949 Geneva Conventions by the government of Afghanistan.

Jerek tortured an innocent man who would then be sent to Ducky for medical care.

Under stress, Ducky eventually made the decision to end the young man's suffering by giving him an overdose of morphine which apparently caused his death, a decision which would haunt Ducky for years.

After his time in Afghanistan, Ducky presumably headed to the United States in 1980, and eventually ended up having a car accident severe enough that he had his arm in a sling afterward due to unfamiliarity with the different driving customs between America and the United Kingdom. He also unintentionally saved an abducted Marine, Leroy Jethro Gibbs, in the same accident, due to the NIS investigating the crash due to the driver, Vito Zucudo of the Zucudo crime family, being involved in laundering money from the Navy and their discovering him in the trunk. It was from this event that they became friends. However, he and Gibbs eventually ended up abducted by the head of the Zucudos, Pete, as well as his right hand man Francis in order to track down the laundered Navy money due to Vito leaving him out of the cut, and attempted to torture Gibbs, although Ducky, mostly because he didn't wish to see Gibbs tortured further or killed, divulged everything he knew about what had transpired. Suspecting a mole within NIS, he eventually deduced that the mole was in fact one of the carpenters working on the then-under renovation bullpin, "Freckles", and told Dr. Walter Magnus this much when meeting him under the pretense of a potential job interview. It was presumably around this time that Mallard joined NIS.

While there, he worked a series of cases under the guidance of the Medical Examiner, Dr. Walter Magnus.

Once Magnus retired, Ducky became his successor.

Abilities

As NCIS's Medical Examiner, Ducky is skilled at performing autopsies on the many victims that he examines with his findings often determining if the victim died of natural causes or if they were murdered.

Ducky also has a Psychological degree, enabling him to perform and create psychological profiles to determine the mindset of the suspects that the NCIS team are currently after which has often come in handy.

Autopsies

Ducky's specialty is performing autopsies with his results often helping the NCIS team pursue other lines of investigation with Ducky himself often determining if the death of a United States Marine Corps or Navy officer was natural or murder.

Psychological Profiling

Having earned a Masters Degree in psychological profiling, Ducky is now capable of creating profiles in which will describe the suspect that the main NCIS team are searching for.

Medical Training

Despite being a Medical Examiner, Ducky's medical skills as a Doctor have often been a huge advantage to members of the NCIS team as he has often treated injuries that the NCIS team have often received in the field.

Trivia

  • When performing autopsies on murder victims, Ducky often talks to them and tells stories about his life.
  • He rarely calls anyone by their nickname, calling Abby "Abigail", Ellie "Eleanor", and Kate "Caitlin."
  • The British Army's culture places heavy emphasis on the pride and traditions of its constituent regiments, featuring marches, nicknames, flags and emblems- all unique. Regimental nicknames are not shared, so the fact that Ducky was in a British Army unit nicknamed "The Regiment" strongly implies he passed selection for and served in the Special Air Service.
  • In Season 2, Episode 13 (Meat Puzzle) Agent Kate Todd asks Gibbs what Ducky looked like when he was younger. Gibbs says "Illya Kuryakin". This is a reference to David McCallum's role as Illya Kuryakin in The Man from U.N.C.L.E. television series.
  • Starting in Season 15, Ducky has appeared less in the series, with Season 17 having him only appear in 6 episodes and Season 18 having him only appear in 3.
  • Starting with Season 19, David McCallum is billed as "with David McCallum", being credited before Rocky Carroll, opposed to the usual "and David McCallum" and being credited after Rocky.
  • His nickname is Ducky because his last name, Mallard, is a kind of duck.
