Adolf Wölfli was born in 1864 and died in 1930. From 1895 until his death, he lived in the Waldau Psychiatric Clinic in Berne. During his more than thirty years' residence he created a comprehensive work of 1460 drawings, collages about 1560 and 25,000 bound to stapling pages. He is considered one of the most important representatives of Art Brut or outsider art. RAWVISION 4-1991, 18-1997, 23-1998 published about him, as well as the Outsider Art Sourcebook.

His psychiatrist Walter Morgenthaler dedicated his 1921 book, "A mentally ill as an artist," which considered and described the first patient suffering from schizophrenia seriously as an artist. It was not until long after his death, his pictorial and poetic work that defies conventional aesthetic categories, became known to a wider audience: the French painter Jean Dubuffet exhibited 120 of Wölflis drawings in the Compagnie de l'Art Brut in Paris. The Documenta 5 in Kassel dedicated the area Artistry of the mentally ill to Adorlf Wölfli in 1972 .

Wölfli's work is held since 1975 in Wölfli Foundation at the Kunstmuseum Bern, scientifically processed and issued. His grave in the Bernese Schosshaldenfriedhof was repealed.Copy and Portrait from «Outsider Art Source Book»
