Arthur Louis Day (October 30, 1869 – March 2, 1960) was an Americangeophysicist andvolcanologist. He studied high temperaturethermometry,seismology andgeothermal energy.
Day was born inBrookfield, Massachusetts[1] and received hisA.B. fromSheffield Scientific School atYale University in 1892. He earn hisPh.D from Sheffield in 1894, and taught at Yale until 1897.[2] Day received anhonorary doctorate from theUniversity of Groningen (The Netherlands) on July 1, 1914.[3][4]
In 1894 and 1895 he worked with German physicistFriedrich Kohlrausch studying theconductive properties ofelectrolytes.[5] From 1897 to 1900 he worked atPhysikalisch-Technische Bundesanstalt inBerlin and began his study of thermometry.[6]
He worked with theU.S. Geological Survey from 1900 to 1907 studying the properties of rocks and minerals at very high and low temperatures.[7] Day served as the director of the Geophysical Laboratory of theCarnegie Institution for Science from 1907 until his retirement in 1936. From 1933 to 1941 he served as vice president of theNational Academy of Sciences.[6] He was president ofThe Geological Society of America in 1938.[8]
Following his retirement, he traveled to New Zealand to continue his study ofseismology andgeothermal energy. He studied the area's volcanic areas until he had to stop his research in 1946 due to poor health.[9]
He died on March 2, 1960, inWashington, D.C.[10]
Day was awarded theJohn Scott Medal, theWollaston Medal, thePenrose Medal, theBakhuis Roozeboom Medal and theWilliam Bowie Medal.[9]
Day was elected to both theAmerican Philosophical Society and theAmerican Academy of Arts and Sciences in 1912.[11]
In 1948, Day established theArthur L. Day Medal through theGeological Society of America. The medal is for "outstanding distinction in contributing to geologic knowledge through the application of physics and chemistry to the solution of geologic problems".[12]
Day was the son of Daniel P. and Fanie (Hobbs) Day. In 1900, he married Helen Kohlrausch, daughter of physicistFriedrich Kohlrausch. Day and his wife had four children: Margaret, Dorothy, Helen and Ralph. In 1933, he married Ruth Sarah Easling. They had no children together.[13]
