Harry Sullivan

Surgeon Lieutenant Harry Sullivan was a Royal Navy surgeon in the employ of UNIT. He was also for a time the companion of the Fourth Doctor. He later worked for NATO and MI5.

He had a younger stepbrother named Will. (AUDIO: Buried Secrets)

Career with UNIT
Harry first encountered UNIT while he worked in the Royal Navy, at the same time the Third Doctor had briefly left Earth in his TARDIS for Peladon. (PROSE: The Face of the Enemy)

After he had joined UNIT and the Third Doctor was apparently in a coma, the Brigadier summoned "Dr Sullivan" to help see him through the process. When Sergeant Benton woke the Doctor by offering him a cup of coffee, the Brigadier cancelled the call for Dr Sullivan's assistance. (TV: Planet of the Spiders)

After confronting the Great One on the planet Metebelis III, the Doctor disappeared. Sarah Jane believed he had died. Three weeks later, the Doctor's TARDIS re-appeared in his laboratory at UNIT HQ. The Doctor had received a fatal dose of radiation, forcing him to regenerate or die. (TV: Planet of the Spiders) Harry Sullivan arrived on the scene just moments after the Doctor regenerated into a new form. (TV: Robot)

Adventures with the Doctor
After the defeat of the robot K1, Harry found himself in the Doctor's TARDIS (TV:Robot). At first very much confused, he trailed the Doctor and Sarah Jane Smith to Space Station Nerva, where they were pitted against the Wirrn (TV: The Ark in Space). Then they travelled by transmat from the space station to an uninhabited far future Earth, where they faced the Sontaran Styre (TV: The Sontaran Experiment). The transmat next took them to Skaro at the time of the creation of the Daleks; this was for a mission from the Time Lords. (TV: Genesis of the Daleks) Via time ring, they travelled back to Nerva, but to a much earlier year. (TV: Revenge of the Cybermen)

Immediately after his adventure with the Cybermen, Harry was ejected from the TARDIS and it stranded him in England, 1936. There Harry met the Eighth Doctor, who had no memory of Harry or any of his previous adventures. Harry helped the Eighth Doctor to stop a Dryad from turning the land of Britain on the people that lived upon it. The Fourth Doctor and Sarah picked Harry up shortly after. (PROSE: Wolfsbane)

Back in the late 20th century, Harry rejoined UNIT to defeat the shape-changing Zygons and their giant, dinosaur-like beast, the Skarasen, in Scotland. After the Zygon's defeat, Harry returned home to London by train rather than by TARDIS. (TV: Terror of the Zygons)

A short time later, Harry helped the Doctor against the Kraals, who had also created an android duplicate of him. (TV: The Android Invasion)

Post-UNIT career
In the early 1980s, Harry worked at NATO. (TV: Mawdryn Undead, PROSE: Harry Sullivan's War)

By 1997, he was Deputy Director at MI5. At that time, via the agency of time travel, he met up once again with a familiar version of the Doctor, as well as a much younger Sarah Jane Smith, for whom little time had passed. (PROSE: System Shock) He still worked for MI5 in 1999. (PROSE: Millennium Shock) By 2005, he was back at NATO, having achieved the rank of Commodore. The Brigadier asked him for a favour at the time. (AUDIO: The Wasting)

To commemorate an anniversary date, Sarah Jane had yearly meetings with Harry Sullivan. By 2006, Harry had been missing in action for some time, though Sarah kept coming to the same place they used to meet. She 'talked' to him and raised a toast to him wherever he was. (AUDIO: Buried Secrets) Harry was still missing in 2009. (PROSE: The Wedding of Sarah Jane Smith)

Sarah Jane indicated that he was dead, and recalled in 2010 that Harry had worked in developing vaccines that had saved thousands of lives. (TV: Death of the Doctor)

In 2015, Harry was alive and discovered a possible cure for HIV in blood taken from David Daniels. (PROSE: Damaged Goods)

Alternative timelines
A parallel Earth version of Harry served on a nuclear submarine in a world taken over by the Silurians after the death of the Third Doctor. He saved the life of the Seventh Doctor's companion Bernice Summerfield. (PROSE: Blood Heat)

Personality
Harry was rather old-fashioned and stereotypically English in his attitudes. He often employed slightly archaic language, referring to Sarah affectionately as "old girl" or "old thing". (TV: The Sontaran Experiment, PROSE: Doctor Who and the Ark in Space) He was brave, one time saving the Fourth Doctor's life from a landmine on Skaro. (TV: Genesis of the Daleks) He had a "can-do" attitude, adapting well to the many strange situations in which he found himself. He could, however, be quite clumsy and unsubtle. This led the Doctor to declare in a moment of frustration, at the top of his lungs, that "Harry Sullivan is an imbecile!", before passing out from the effects of a rockfall on Voga – caused by Harry. (TV: Revenge of the Cybermen) He flirted a bit with Sarah. Despite an outward annoyance at that attitude, once when thinking him dead, Sarah admitted she found it endearing. (PROSE: Wolfsbane)

He was good at cricket, and was able to throw a cricket ball over at least a metre. (PROSE: Doctor Who and the Ark in Space)

Relatives
Harry had a stepbrother named Will, whom Sarah Jane Smith met in 2006. (AUDIO: Buried Secrets) Will was killed by Josh Townsend shortly after meeting her. (AUDIO: Fatal Consequences)

Behind the scenes

 * Harry has many similarities to Martha Jones: They both worked as medical officers for UNIT whilst working with other organisations, they both had adventures with the Doctor after leaving the TARDIS, both were posessed by enemies of the Doctor, and they both battled Davros, Daleks and Sontarans.
 * Harry was created as a companion when it was thought that the Fourth Doctor would be played by an older actor who would not be able to handle the physical side of the series. This would necessitate Harry handling physical "two-fisted" action as the plot required. This was not a concern when the 40-year-old Tom Baker was cast in the role, as he was somewhat younger than the previous actors and capable of physical action on his own. Harry was thus deemed redundant and ultimately written out of the show, despite his popularity.
 * Harry is a member of a small group of companions who had no scenes in the TARDIS interior. He is seen entering and emerging from the TARDIS several times, but he is never seen within the TARDIS itself.
 * Ian Marter reappeared as Harry in The Android Invasion. Sadly, there were to be no further guest appearances, as the Doctor Who production team had by this time decided to phase out UNIT and sever the Doctor's links with Earth.
 * It was hoped Ian Marter would reprise the role of Harry for the 20th Anniversary story The Five Doctors in 1983, but Marter had to turn down the offer, as he was committed workwise at the time.
 * Although various spin-off media have depicted Harry living into the 21st century, in real life the actor who portrayed him, Ian Marter, died in 1986. A reference to the character is made in TV: Invasion of the Bane, when Sarah Jane considers Harry as a possible name for her adopted son, Luke Smith. Perhaps going along with this fact, it has been implied that Harry has indeed already passed away in the present-day continuity of the Doctor Who universe, as in TV: Death of the Doctor, when recounting the current endeavours of some of the Doctor's past companions, Sarah Jane refers to him in past tense.
 * There is an apocryphal account presented in Doctor Who and the Rebel's Gamble suggesting that at some point Harry Sullivan shared an adventure with the Sixth Doctor.
