Also known as: Arthur Louis Day
Arthur L. Day (born Oct. 30, 1869, Brookfield, Mass., U.S.—died March 2, 1960, Washington, D.C.) was a U.S. geophysicist known for his studies of the properties of rocks and minerals at very high and very low temperatures. He investigated hot springs and earthquakes, the absolute measurement of high temperatures, and physical and chemical problems regarding volcanoes.
Day was with the U.S. Geological Survey from 1900 until 1907, when he became director of the Geophysical Laboratory of the Carnegie Institution of Washington, Washington, D.C.; he retired in 1936. He was vice president of the National Academy of Sciences (1933–1941) and president (1938) of the Geological Society of America, which created the Arthur L. Day Award in his honour.
