“I am indifferent to humanity,” the artist Tetsumi Kudo, who died in 1990, wrote in a letter to a friend. “I look upon skins as I look upon fossils.” Kudo grew up in Japan, in the aftermath of the atomic bombings of Hiroshima and Nagasaki. His sculptural installations imagine a grotesque future—a “new ecology”—where human body parts merge with the twisted remnants of our natural world, and pollution alters the color of flowers and faces. Kudo’s radical vision was ahead of its time, but now we’ve caught up with him. These works are both surreal and surprisingly prophetic. —E.C.
