Cook, Charles Sumner, 1857-1934



  • Existence: 1857 - 1934

Charles Sumner Cook was born on June 20, 1857 in Keene, New Hampshire. In 1875, he entered the Chandler Scientific Department of Dartmouth College and graduated in 1879. He remained at Dartmouth eight years after graduating, tutoring mathematics at the Chandler School until 1883 and then becoming an instructor of physics and astronomy at the College. One of his duties at Dartmouth was making weather observations, and he did pioneer work in use of the spectroscope to forecast weather by distinguishing rain bands. A paper on the subject brought him to the attention of American and European scientists, leading to the incorporation of his work in spectroscopy in the article on rain bands in the revised 9th edition of the "Encylopaedia Britannica." In 1887 Cook was appointed professor of physics and astronomy at Northwestern University. Cook died on May 27, 1934.
