Peter Dreher (1932), who recently passed away on February 20, 2020 at the age of 87, was a German artist and academic teacher, influencing artists such as Anselm Kiefer.
In 1974, he began his series Tag um Tag guter Tag (Day by Day, good Day). In this series, he initially intended to paint a drinking glass only five or six times. Dreher, however, found that he did not want to stop, instead deciding to stop “when the motivation stopped,” which was not until the 2010s.
Dreher painted the drinking glass more than 2,500 times at night and more than 2,500 times during the day, in a process similar to meditation, always at life-scale, centered on a 25 x 20 cm neutral grey background, and from the same distance. He has been lauded for his ability to make “this simple thing deeply unsimple” (Emily Hall, Art Forum), creating “an aggregate of still paintings and temporal movement, like a decades-long filmstrip that follows no logic and evinces no progression.”
