Light and space, transparency and beauty were the ideals in the art of Adolf Luther (1912-1990). More than many another artist, 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 their development. The monograph traces the development of this remarkable artist. From an early stage he crossed the borders of the traditional genre divisions in art, becoming an inspiration and role model for many contemporary 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. The publication closes the gaps in research and attempts a new assessment of Luther's artistic achievements.
