"In fact, Dieter W. Liedtke's works, which gave shape to his visions of the abstraction of visual art, are comparable in their significance to the sketches and models of a Leonardo da Vinci, because they recorded and depicted real and significant scientific findings at a time, when the respective scientific disciplines themselves were still distant from them." 

"Just as da Vinci's works on aerodynamics, anatomy or statics are today have appropriate value as a world heritage site, since they bear witness to the performance of a mind that was far ahead of its time, will also be Dieter W. Liedtke's works increase in value according to the dissemination of their contents".

They open up a new world for the viewer, art historian and researcher."

"For the first time in art history, statements manifested in Dieter Liedtke's artworks and theories have been substantiated as research findings decades after they were created and published, by research conducted by scientists who were unaware of his artworks; for the researchers in question, they have led to Nobel Prizes in the subjects of medicine, physics as well as economics. “
