Born in 1931 in Lollar, Germany), Heinz Mack attended the Academy of Arts Düsseldorf during the 1950s. In 1957, he founded the group ZERO together with Otto Piene.
“For me, light is immaterial,” Mack explained. “In my case, I prefer to make works that are instruments for light. My sculptures do have a kind of function: of making light visible.” A painter and sculptor, Mack is known for his investigations into luminescence, space, movement, and color, rendered through an array of materials. He participated in the Documenta II (1959) and Documenta III (1964), and represented The Federal Republic of Germany at the XXXVth Venice Biennale in 1970.
