Within several years, Prinzhorn assembled "the largest and finest" collection of art by psychotic patients in Europe; he went on to use this material for a "revolutionary new publication," Artistry of the Mentally Ill(2). "Reaction to the book was such that Prinzhorn’s reputation was established by it; he became famous overnight" (1). Prinzhorn, however, left the Heidelberg Clinic in 1921, before the publication of the book, at which time the collection included some 5,000 works of art (by about 500 patients) that had been collected from about 1890 to 1920 (1). These works came mainly from European psychiatric institutions. Although the collection was intended to serve as an archive for research in art and psychiatry, some time after Prinzhorn’s death in 1933 it was packed away and stored in the hospital attic. There it remained until recent decades, when it was restored, catalogued, and made available for exhibition. Beyond Reason: Art and Psychosis: Works From the Prinzhorn Collection is the catalogue of an exhibition held in London’s Hayward Gallery, December 5, 1996, to February 23, 1997. The present volume, containing three essays and 186 photographs, 155 of which are in color, was published by the University of California Press in association with the Hayward Gallery in 1998.
