Harry Houdini

Harry Houdini was a famous American magician and escapologist on Earth during the 20th century.

Biography
Before moving to America, Houdini was born in Hungary. He was later ashamed of his origins during World War I. (AUDIO: Harry Houdini's War)

Houdini first met the Doctor in 1890, when the Doctor was in his first incarnation, although this was not their first encounter from the Doctor's perspective. At the time, the Doctor was accompanied by Ben Jackson and Polly Wright. Together, the four of them defeated the Ovids. At some point after this, Houdini met the Third Doctor, and travelled to the future with him and Jo Grant. (AUDIO: Smoke and Mirrors)

At one point before 1917, Houdini and the Doctor also faced the Kleptons. At one point, he saved the Doctor from a Salatian mine bomb. (AUDIO: Harry Houdini's War)

Between 1917 and 1920, Houdini, along with Sir Arthur Conan Doyle, publicly announced the existence of fairies following the release of the Cottingley fairy photos. Gwen Cooper believed this was all an act of self-publicity. (TV: Small Worlds)

In 1920, the Eleventh Doctor needed help defeating the Cuculus and decided to recruit Houdini during his act. When they were captured by the Cuculus, Houdini was easily able to break the locks holding him and the Doctor. After the Doctor defeated the Cuculus, they returned them to Earth and the Doctor returned him to his act. When people started getting sick, the Doctor realised that the Cuculus had infected them with a disease to wipe out humanity. Using a crystal from the Cuculus ship that Houdini had stolen, the Doctor was able to cure the disease. (PROSE: Houdini and The Space Cuckoos)

In 1925, Houdini was trapped in a computer program inside a crystal ball which simulated the theatres he had visited and begun feeding on his despair. He called the Twelfth Doctor for help, but the Doctor and Clara Oswald's minds were also trapped inside. The program set up theatrical death traps with no way out so their minds could be ripened for it, but the Doctor, Clara and Houdini escaped. The Doctor revealed the virtual environment with his sonic screwdriver, and the three of them thought of the things that made them feel the most free to break their minds out of the crystal, destroying it. Houdini lost hope in ever communing with the dead, but the Doctor and Clara assured him that his reputation would outlive him. (COMIC: Theatre of the Mind)

The Fifth Doctor, Adric, Nyssa and Tegan Jovanka later met Houdini when the Doctor answered a psionic distress call being sent from England in the 1920s. Unbeknownst to the Doctor and his companions, Houdini had been convinced by that the Doctor was evil. Houdini's relationship with the Doctor, already tense due to the Time Lord's refusal to offer the performer any clues as to his personal future (in particular whether he would ever be able to communicate with his deceased mother in the spirit world), became strained as a result of the incident. (AUDIO: Smoke and Mirrors)

The Eighth Doctor also met Houdini when he was travelling with Lucie Miller. Houdini taught Lucie how to escape from handcuffs during this time. (PROSE: The Great Escapes)

At some point before his time on Destination, a young Master met Houdini, and was taught escapology. (AUDIO: The Destination Wars)

At some point, Houdini taught the Doctor escapology, including a few tricks the Doctor used numerous times over many lifetimes to get out of a bind. (PROSE: The Sorcerer's Apprentice, Mission to the Unknown, TV: Planet of the Spiders, Revenge of the Cybermen, AUDIO: Summer, 1001 Nights, The Church and the Crown, The Mind's Eye, COMIC: Voyager, Façades, AUDIO: Project Twilight, PROSE: Cat's Cradle: Time's Crucible, Independence Day, AUDIO: The High Price of Parking, PROSE: Frontier Worlds, TV: Dreamland, GAME: Shadows of the Vashta Nerada, TV: The Witchfinders)

Copies and imitations
In 1904, the Thirteenth Doctor escaped 200 cyborg clones of Houdini in the subways of New York City. (PROSE: The Secret in Vault 13)

Behind the scenes
Houdini actually never investigated the Cottingley photos, despite some correspondence from Doyle that suggested he visit. Houdini was shown to be involved in the events in the 1997 film FairyTale: A True Story starring Paul McGann.
