Günther Uecker, a prominent figure in post-war German art, has passed away at 95. Renowned for his nail reliefs, he created textured surfaces by hammering nails into various objects. Born in 1930 in Wendorf, he gained fame after moving to Düsseldorf, where he became part of the ZERO group. Uecker's work often conveyed messages of peace and human rights, and he maintained an anti-establishment stance throughout his career.
