In 2472, the Master stole Jurgens's identifications and 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; 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.

According to another account, the Adjudicator's name was Martin Jurgen. The Doctor speculated that the Master must have killed him in order to steal his identity. Doctor Who and the Doomsday Weapon)

Behind the scenes

Jurgens never appears in person, but his photograph appears in two scenes in the fifth episode. In fact, Jurgens is represented with a photograph of Graeme Harper, the serial's assistant floor manager. Harper poses 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.
