Daniel Paul Schreber (; 25 July 1842 – 14 April 1911) was a German judge who was famous for his personal account of his own experience with schizophrenia. Schreber experienced three distinct periods of acute mental illness. The first of these, in 1884-1885 was what was then diagnosed as dementia praecox (later known as paranoid schizophrenia or schizophrenia, paranoid type). He described his second mental illness, from 1893 to 1902, making also a brief reference to the first disorder from 1884 to 1885, in his book Memoirs of My Nervous Illness (). The Memoirs became an influential book in the history of psychiatry and psychoanalysis because of its interpretation by Sigmund Freud. There is no personal account of his third disorder, in 1907–1911, but some details about it can be found in the Hospital Chart (in the Appendix to Lothane's book). During his second illness he was treated by Prof. Paul Flechsig (Leipzig University Clinic), Dr. Pierson (Lindenhof), and Dr. Guido Weber (Royal Public Asylum, Sonnenstein). Schreber's experiences Schreber was a successful and highly respected judge until middle age when the onset of his psychosis occurred. He woke up one morning with the thought that it would be pleasant to "succumb" to sexual intercourse as a woman. He was alarmed and felt that this thought had come from somewhere else, not from himself. He even hypothesized that the thought had come from a doctor who had experimented with hypnosis on him; he thought that the doctor had telepathically invaded his mind. He believed his primary psychiatrist, Prof. Paul Flechsig, had contact with him using a "nerve-language" of which Schreber said humans are unaware. He believed that hundreds of people's souls took special interest in him, and contacted his nerves by using "divine rays", telling him special information, or requesting things of him. During one of his stays at the Sonnenstein asylum, he concluded that there are "fleeting-improvised-men" in the world, which he believed were divinely fabricated men, as miracles to provide Schreber with "play-with-humans" in light of a depopulation of the world. As his psychosis progressed, he believed that God was turning him into a woman, sending rays down to enact 'miracles' upon him, including little men to torture him. Schreber was released from psychiatric hospitals around 1902, shortly before the publication of his book. He resumed his private activities, which he conducted very well up until 1907, when his
