gunther uecker german artist died

German artist Günther Uecker, renowned for his spiritual approach to art and innovative use of nails as a sculptural material, died on Tuesday at age 95 in a Düsseldorf hospital. His family confirmed the death to German news agency dpa, though no cause was given. Uecker was a key member of the Zero Group, which sought to reset art to a "zero base," and his work ranged from nail-covered surfaces to pianos, chairs, and television sets. He also designed a prayer room for Berlin's Reichstag and participated in major exhibitions including Documenta 4 and the Venice Biennale.
