Hans Mögel had already discovered the MDE at the end of the 1920s and described it in a lecture given by the German Geophysical Society on September 12, 1930 . In 1935, Dellinger described the standardization authority's MDE. In 1938 he received the IRE Medal of Honor and a moon crater was named after him.
