Verschwinden von Restmudigkeit, 1987 / Begleitung zu fliessbandahnlichen Arbeiten, 1988 / Vierermannchen, 1986 / Der echte Feuerfrier - Effekt, 1989
from Dietrich Orth, Portikus Frankfurt am Main, 1997 (german language)
"In his work, Orth investigates a variety of subjects including his own body language, the effects of his prescribed psycho-pharmaceuticals and particular mental/emotional states like rage or dignity. " (from here)
"any smaller or larger disturbances of the feeling of being undisturbed have to be corrected, sublimed, or rerouted." and "the observation and development of the smallest little piece of satisfaction is the strongest weapon against social chaos." - Dietrich Orth (from Artforum, Sept. 1994)
