Light and space, transparency, and beauty were the ideals in the art of Adolf Luther (1912-1990). His numerous light integrations and optically fascinating concave-mirror objects left their mark on the reality and aesthetics of the Bonn Republic. This magnificent volume provides a new look at his works and development as an artist. From an early stage, he crossed the borders of traditional genre divisions in art, becoming an inspiration and role model for many artists today. Ultimately, Luther’s art collection, extending from Beuys to Ad Reinhard, testifies to an unconventional and open mind that continues to deserve to be rediscovered. This book closes the gaps in research and offers a new assessment of Luther’s artistic achievements.
