From Tardis Wiki, the free Doctor Who reference
Robert Salmon was a computer programmer and a hacker.
The Fifth Doctor got his help in 1975 to stop Professor Xerxes from installing a backdoor to navy software that would have allowed access any time he wished. In 1980, the Sixth Doctor asked him to aid in the retrieving of the cargo of an Eridani spacecraft that had crashed on Earth years before. (PROSE: Blue Box)
