„I have always known that I want to be a scholar. That it is a worthy thing for a man to work at the university and discover the secrets of nature. Scientific work was not a revelation, it was not a change in life direction – except my first dream to be a pearl diver. It was all from the nature, from home.“
— Jerzy Vetulani Polish scientist 1936
