wikipedia.org: "Adolf Wölfli (1864 - 1930) (occasionally spelt Adolf Woelfli or Adolf Wolfli) was a prolific Swiss artist who is regarded as one of the foremost artists in the Art Brut or outsider art traditions.

Wölfli had a troubled childhood. He suffered abuse and molestation and was orphaned at the age of 10, thereafter growing up in a series of state-run foster homes. He worked as a farm labourer and briefly joined the army but was later convicted of attempted child molestation for which he served prison time. Sometime after being freed he was arrested for a similar offence and was admitted in 1895 to the Waldau Clinic in Berne, Switzerland, a psychiatric hospital where he spent the rest of his adult life. He was very disturbed and sometimes violent on admission, leading to him being kept in isolation for his early time at hospital, perhaps due to his psychosis which led to intense hallucinations."
