John Adam Fleming
John Adam Fleming (born January 28, 1877 in Cincinnati , Ohio , † July 29, 1956 in San Mateo , California ) was an American geophysicist .
After completing his bachelor's degree in civil engineering (1899) at the University of Cincinnati, Fleming was an assistant to the US Coast and Geodetic Survey until 1903 , where he worked under Louis Agricola Bauer in the newly established department of Terrestrial Magnetism , the geomagnetic observatories in Alaska, Hawaii and Maryland, and from 1903 to 1904 Superintendent of Design and Construction at Vulcan Copper Works. From 1904 to 1910 he was a Magnetic Observer for the US Coastal and Geodetic Survey. At the same time he was from 1904 Chief Magnetician at the Carnegie Institution in Washington, DC , where Bauer had founded the Department of Terrestrial Magnetism (DTM) in 1904 . He designed, built and looked after geomagnetic instruments there and was involved in observation, for example in Central America. He became Chief of the Observatory Division , Chief of the Magnetic Survey Division , became Assistant Director in 1922 (after Director Bauer's health gradually deteriorated), Acting Director in 1930, and from 1935 to 1946 he was Director of the Department of Terrestrial Magnetism of the Carnegie Institution . From 1946 to 1954 he was an international relations advisor to the Carnegie Institution.
From 1925 to 1947 he was editor of the Transactions of the American Geophysical Union and from 1928 to 1948 of the Journal of Terrestrial Magnetism and Atmospheric Electricity (now Journal of Geophysical Research ) of the American Geophysical Union . From 1930 to 1953 he was on the Council (Board of Trustees) of the Woods Hole Oceanographic Institution . Not least because of his organizational skills, he was one of the most important personalities who shaped geophysics in the USA in the first half of the 20th century. At the DTM he supported Sydney Chapman and Julius Bartels in the preparatory work for their classic book Geomagnetism (1940). Fleming himself published over 100 scientific papers. One of his main areas of research was the secular variation of the earth's magnetic field.
The John Adam Fleming Medal of the American Geophysical Union is named in his honor.
In 1938 Fleming became a member of the National Academy of Sciences . He was an honorary doctor from the University of Cincinnati (1933) and Dartmouth College (1934). He received the William Bowie Medal from the American Geophysical Union in 1941 and the Chree Medal from the Physical Society in London.
