Nobuo Sekine

Nobuo Sekine (関根伸夫, 1942–2019) was a Japanese sculptor whose 1968 earthwork Phase—Mother Earth is taken as the founding work of Mono-ha. Trained under Yoshishige Saitō at Tama Art University, he exhibited at the 6th Paris Youth Biennale in 1969, the same edition that showed the Computer Technique Group; his phase works and prints draw on topology.
