Sigmund Freud

Sigmund Freud was a psychiatrist in the 20th century.

Freud was born and lived in Austria for the entirety of his youth. He visited London in 1894 where he met Henry Gordon Jago and George Litefoot. Freud helped the duo to stop the physical manifestation of Litefoot's mind from causing trouble. (AUDIO: Return of the Repressed)

Freud had argued that there were great untapped parts of the human brain which could be explored at times of illness or stress. He had tried to explain existence in terms of mere cause and effect. The Seventh Doctor called Freud "a dreadful man with a big beard." (PROSE: The Pit)

The Doctor had not, by the time that his sixth incarnation was travelling with Charlotte Pollard, met Freud. (AUDIO: Brotherhood of the Daleks)

When Grace Holloway jokingly told that the Eighth Doctor liked being called "Doctor", she recalled that Freud had a name for that. The Master answered with "transference". The Doctor sarcastically called Grace "witty" for that remark and claimed that "at least Freud would have taken me seriously." Grace thought that Freud would have "hung up his pipe" if he met him, to which the Doctor replied he had met him and they "got on very well". (TV: Doctor Who)

The Master met Freud, whom he described as "a joy", and gave him his first box of cigars. (AUDIO: Death Match)

Freud regularly destroyed all of his notes to preserve the anonymity of his often-wealthy clients. He gathered (and destroyed) extensive material on the Hauserkinder. (PROSE: The Book of the War)

The Eighth Doctor visited Freud sometime during the 20th century while he was suffering from amnesia in an attempt to jog his own memory. (PROSE: The City of the Dead) He asked Freud about his phobia about silverfish, but Freud wouldn't tell him what he'd said under hypnosis. (PROSE: Grim Reality) Freud wrote a book called The Interpretation of Dreams. (PROSE: Evergreen) The Doctor once taught him a form of hypnotism. (AUDIO: The Girl Who Never Was)

In 1699, the Eleventh Doctor mentioned that Freud would say that Captain Henry Avery waving his gun around was a form of compensation, and that Freud had a comfy couch. (TV: The Curse of the Black Spot) Freud had told him that, when confronted with the unbelievable, the human brain would go into shock. (PROSE: Borrowed Time)

Far after Freud's lifetime, the Freudian Institute was staffed entirely by robot Sigmund Freuds, each sharing all information gained in their psychoanalytic sessions with all other robot duplicates. This allowed them to communicate while in separate sessions with the Sixth Doctor and Peri Brown. (AUDIO: Conflict Theory)
