Biography

Martin Jurgens (TV: Colony in Space) or Martin Jurgen (PROSE: Doctor Who and the Doomsday Weapon) worked for the Guild of Adjudicators. In 2472, the Master stole Jurgens' credentials (TV: Colony in Space) and, the Third Doctor assumed, killed him and atomised his body or left him in space. (PROSE: Doctor Who and the Doomsday Weapon)

The Master travelled to Uxarieus, posing as an Adjudicator in a scheme to gain control of the Doomsday Weapon. Captain Dent, growing suspicious, requested a copy of the Adjudicator's credentials from Earth Control; when they sent back a photograph of Jurgens, Dent realised he was dealing with an impostor. Later, Jo Grant found Jurgens's original credentials in the Master's TARDIS, which was camouflaged as an Adjudicator's spaceship; she showed the credentials to the Third Doctor, who kept them.

Appearance

According to one account, Jurgens was a light-skinned man with curly hair and a beard, and in his identity photograph wore an Adjudicator's rigid black and silver robe with a tall stiff collar. (TV: Colony in Space) According to another, he was a clean-shaven man with a round chubby face, blue eyes, and fair hair. (PROSE: Doctor Who and the Doomsday Weapon)

Behind the scenes

The photo of Graeme Harper reused as an earlier incarnation of the Doctor in The Brain of Morbius

Jurgens never appears in person, but his photograph appears in two scenes in the fifth episode. In reality, this was a photograph of Graeme Harper, the serial's assistant floor manager, posing in the same black Adjudicator robe that the Master wears while incognito.

Five years later, a close-up on the same photograph was used to represent one of the Doctor's earlier incarnations in The Brain of Morbius (along with seven other photos, all taken specifically for that serial). The unusual provenance of the Harper photo was not widely known until 2020, when it was confirmed and publicised by Paul Hanley. Noting the production team's difficulty finding volunteers for the photoshoot, Hanley said that the Harper photo was probably taken from the archive and reused for convenience, but that "the ramifications for this are kinda wild, since there's a strong case to be made that Colony in Space is now the first appearance of a pre-Hartnell Doctor, and he's even mixed up in the plot in a way that seems appropriate for a secret agent of the Time Lords!"
