On June 20, 2024, Lévy Gorvy Dayan opened Material States: Yves Klein and Günther Uecker, an exhibition exploring connections between Yves Klein (1928–1962) and Günther Uecker (b. 1930). Titans of Europe’s postwar avant-garde, Klein and Uecker developed radically alternative visual languages at a time when artistic traditions were increasingly questioned and dismantled. The artists’ lives converged in manifold ways, and, in January 1962, Klein married Uecker’s sister Rotraut, rendering the two family. Material States included major works by each artist, including Uecker’s poignant Hommage à Yves Klein II, created the same year as Klein’s untimely death at the age of 34.
