Did you know?
In 1900, in the year that John Haffey 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.
Did you know?
In 1917, John was 17 years old when Dutch exotic dancer Mata Hari was convicted and executed as a German spy. Since Mata Hari, born Margaretha Geertruida "Margreet" MacLeod, was a citizen of the Netherlands (which remained neutral in World War 1), she could travel freely in Europe. Her travels (and her romantic entanglements) raised suspicion and she was arrested by the French and found guilty. There is still controversy about her guilt although her name has become synonymous with a seductive female spy.
