Theodor Hermann Meynert was a German-Austrian psychiatrist, neuropathologist, and anatomist born in Dresden. Meynert believed that disturbances in brain development could be a predisposition for psychiatric illness and that certain psychoses are reversible.

Sigmund Freud was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies seen as originating from conflicts in the psyche, through dialogue between patient and psychoanalyst, and the distinctive theory of mind and human agency derived from it.
