John Howard Dellinger

John Howard Dellinger ( born July 3, 1886 in Cleveland, Ohio, † December 28, 1962 ) was an American telecommunications engineer who discovered how sunspots shortwave long distance communications interrupt ( Mögel - Dellinger effect, MDE).

After completing his studies at Western Reserve University and George Washington University, where he earned his Bachelor of Arts in 1908, he received his Ph.D. in 1913 at Princeton University. In 1932, he earned his second doctorate at George Washington University.

From 1907 to 1948 he worked at the National Bureau of Standards as a physicist and head of the Central Radio Propagation Laboratory. In addition, he was still in charge of several other committees.

Hans Mögel had discovered in the late 1920s the MDE and described on 12 September 1930 in a lecture by the German Geophysical Society. 1935 Dellinger described the MDE standardization authority. In 1938 he received the IRE Medal of Honor and a lunar crater named after him.
