Hans-Hermann Hupfeld
Gustav Theodor Hans Hermann Hupfeld (November 28, 1905 – November 11, 1942) was a German physicist known for his work on the scattering of gamma rays.
==Early career==
Hans-Hermann Hupfeld was born on his parents' farm in Klein-Varchow, Mecklenburg, Germany. He obtained a degree in physics and worked at the Kaiser Wilhelm Institut, Berlin Dahlem, from 1929 until 1932 with Prof. Otto Hahn and Prof. Lise Meitner. His research during that time resulted in the discovery of the so-called Meitner–Hupfeld effect.
The Meitner-Hupfeld effect is an anomalously large scattering of Gamma rays by heavy elements. Later on, the Meitner–Hupfeld effect was explained by a broad theory from which evolved the Standard Model, a theory for explaining the structure of the atomic nucleus. The anomalous gamma-ray behavior was eventually ascribed to electron–positron pair production and annihilation.
Although Professor Meitner was recognized for her work, Hupfeld is usually ignored, and little or no account of his life exists. His name is misspelled as Heinz Hupfeld, instead of Hans-Hermann Hupfeld in publications from the early '30s.
