Sigmund Freud, 1856 - 1939 (Dramatised): Explorers and Pioneers, Volume Four

Sigmund Freud will be remembered by most people for the "slip" that bears his name. A few more will associate him with dreams that have a meaning: usually of a sexual nature and filled with symbolism - particularly the phallic symbolism beloved by advertisers.

In fact, Freud's work fills 24 volumes and ranges over topics from the anatomy of the brain to the structure of primitive tribes. However, the most far-reaching of Freud's contributions is arguably that of psychoanalysis. He developed it, claimed to have made staggering discoveries with it, and used these discoveries to propose theories about human behaviour that are still the subject of heated debate.
