Jan Schoonhoven’s drawing exhibition at Peter Freeman was the artist’s first solo show in the United States since 1999. A cofounder in 1960 of Nul—the Dutch complement to the German Zero Group—Schoonhoven (1914-1994) played an important role in the reductionist, materially conscious, and conceptually motivated European art scene of the ’60s and ’70s. He participated in many of the Zero Group’s exhibitions, along with Otto Piene, GuÌ?nther Uecker, Heinz Mack, Piero Manzoni and Lucio Fontana, among others.
