Harlan True Stetson

Harlan True Stetson (1885–1964) was an American astronomer and physicist.[1]

He earned a B.S. from Brown University in 1912, a M.A. from Dartmouth College, then a Ph.D. at Harvard University in 1915. His thesis was titled, On an Apparatus and Method for Thermo-Electric Measurements for Photographic Photometry.

Stetson joined Dartmouth in 1918 to teach physics, then moved to Harvard where he taught astronomy until 1929. He then became the director of the Perkins Observatory in Delaware, Ohio.

In 1936 he joined the Massachusetts Institute of Technology. He directed the MIT Cosmic Terrestrial Research Laboratory from 1940 until 1950, and performed research into the relationship between the cosmos and the Earth. His studies included sunspots, the Earth's crust, and the propagation of radio waves.

The crater Stetson on the Moon is named in his honor.

He is also the author of multiple articles on astronomy.

gollark: Have you *never* looked at that?
gollark: Surely you must have some idea. They're in Task Manager.
gollark: What are the actual *specs*, though?
gollark: For example, because of a better scheduler and stuff Threadripper (some Ryzen stuff too?) ran significantly better under Linux for a while, I think.
