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, Dr. Hupfeld is usually ignored, and little or no account of his life exists.
