In 1900, in the year that John Geist was born, the German physicist Max Planck formulated an energy theory, postulating the existence of "quanta," which lays the groundwork for the quantum theory of modern physics. In December, he introduced a paper on the Planck postulate which stated that E=hv - the energy of a photon is proportional to its frequency times a constant. Planck won a Nobel Prize in 1918 for his work in theoretical Physics.

In 1919, John was 19 years old when in June, the Treaty of Versailles - officially ending World War I - was signed. The European Allies demanded "compensation by Germany for all damage done to the civilian population of the Allies and their property by the aggression of Germany by land, by sea and from the air.” The requirement of compensation is seen by most as the reason for the collapse of the German economy and gave rise to the rule of Hitler.
