Lemuel Gulliver was a fictional adventurer who was the protagonist of the novel Gulliver's Travels, by Jonathan Swift.
When the Second Doctor was in the Land of Fiction, he encountered a man dressed in 18th century clothing and who spoke only in lines attributed to Gulliver in the novel. From this, the Doctor eventually deduced that this person was Lemuel Gulliver. (TV: The Mind Robber)
On his next visit to the Land of Fiction, the Doctor was reunited with Gulliver, only to learn that he was in fact the Time Lord Goth, who had been sent to the Land by the Celestial Intervention Agency to monitor the Doctor's activities there. (PROSE: Future Imperfect)
