I grew up in Muenchen where my father has been a professor for pharmaceutic chemistry at the university. He had studied chemistry and medicine, having been a research student in Leipzig with Wilhelm Ostwald, the Nobel Laureate 1909. So I became familiar with the life of a scientist in a chemical laboratory quite early.
After finishing the gymnasium in Muenchen with 9 years of Latin and 6 years of ancient Greek, history and philosophy, I decided to become a physicist. The great theoretical physicist Arnold Sommerfeld, an university colleague of my late father, advised me to begin with an apprenticeship in precision mechanics.
In 1952, I was appointed Professor at the University of Bonn and Director of the Physics Institute, with very good students waiting for a thesis advisor.
I was born on August 10, 1913, in Lorenzkirch, a small village in Saxony, as the fourth child of Theodor and Elisabeth Paul, nee Ruppel. All in all, we were six children. Both parents were descendants from Lutheran ministers in several generations.
