July 7, 1909, the thread of life of the talented young scientist Walter Ritz, who managed to do a lot in science in 31 years of his life, broke off. To this day, the Ritz combinational principle is used in spectroscopy, and the Ritz variational method in physics, mathematics and technology. However, his other, even more important scientific developments are forgotten, due to their discrepancy with the dogmas of the theory of relativity and quantum physics.
