Their scientific and practical accomplishments greatly contributed to the development of modern urology. The author analyzes the fact that the history of medicine gives rich material not only for understanding evolution but also for the possibility to foresee its further development. The current state of clinical urology has been achieved by the progress of basic research in biology, physics, biochemistry, bacteriology, immunology, pharmacology. At the same time, the personality of the scientist-physician, his observation, non-standard view, the ability to see the opening perspectives, to bring up worthy successors and create a scientific and clinical school of urologists, is of utmost importance. The great German urologists J. Israel and M. Nitze had all these fundamental characteristics of a great scientist-physician.
