Adolf Wölfli was a Swiss outsider artist. He was abused both physically and sexually as a child, and was orphaned at the age of 10. He thereafter grew up in a series of state-run foster homes. He was later convicted of attempted child molestation, for which he served prison time. After being freed, he was re-arrested for a similar offense and in 1895 was admitted to the Waldau Clinic, a psychiatric hospital in Bern 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. He suffered from psychosis, which led to intense hallucinations.
