Arthur Louis Day (October 30, 1869 – March 2, 1960) was an American geophysicist and volcanologist. He studied high temperature thermometry, seismology and geothermal energy.
Day was born in Brookfield, Massachusetts and received his A.B. from Sheffield Scientific School at Yale University in 1892. He earn his Ph.D from Sheffield in 1894, and taught at Yale until 1897. Day received an honorary doctorate from the University of Groningen (The Netherlands) on July 1, 1914.
In 1894 and 1895 he worked with German physicist Friedrich Kohlrausch studying the conductive properties of electrolytes. From 1897-1900 he worked at Physikalisch-Technische Bundesanstalt in Berlin and began his study of thermometry.
He worked with the U.S. Geological Survey from 1900-1907 studying the properties of rocks and minerals at very high and low temperatures. Day served as the director of the Geophysical Laboratory of the Carnegie Institution for Science from 1907 until his retirement in 1936. From 1933-1941 he served as vice president of the National Academy of Sciences.
Following his retirement, he traveled to New Zealand to continue his study of seismology and geothermal energy. He studied the area's volcanic areas until he had to stop his research in 1946 due to poor health.
