Thomas Sterry Hunt (September 5, 1826 – February 12, 1892) was an Americangeologist and chemist.
Biography
Hunt was born at Norwich, Connecticut. He lost his father when twelve years old, and had to earn his own livelihood. In the course of two years he found employment in a printing office, in an apothecary shop, in a book store and as a clerk. He became interested in natural science, and especially in chemical and medical studies, and in 1845 he was elected a member of the Association of American Geologists and Naturalists at Yale—a body which four years later became the American Association for the Advancement of Science.[1]
In 1857, he invented a chromium oxide-based ink[10] while teaching at Université Laval, in response to an appeal for measures to fight counterfeiting. The ink ended up being used on various bank notes, including the US government's Civil War bank notes. This is the origin of the term "Greenback".[11]
In 1859 he was elected fellow of the Royal Society, and he was one of the original members and president of the Royal Society of Canada. In 1861, he was elected as a member of the American Philosophical Society.[12] He was made Chevalier or the Legion of Honor in France and an honorary doctor of laws of the University of Cambridge. He was a frequent contributor to scientific journals, writing on the crystalline limestones, the origin of continents, the chemistry of the primeval earth, on serpentines, etc. He also wrote a notable Essay on the History of the names Cambrian and Silurian (Canadian Naturalist, 1872), in which the claims of Adam Sedgwick, with respect to the grouping of the Cambrianstrata, were forcibly advocated.[1] Hunt was elected a member of the National Academy of Sciences in 1873.[13]
Building upon John Tyndall's research on greenhouse gases, Hunt first proposed the theory which linked climate change from the Carboniferous to the modern age to concentrations of carbon dioxide in the atmosphere in an 1863 submission to the American Journal of Science and Arts.[14] He further explored at a meeting for the British Society for the Advancement of Science in the fall of 1878. This was well before Arrhenius established the theory of the greenhouse effect. Hunt later hypothesized that the high concentrations of atmospheric carbon dioxide in the geologic past was of cosmic, rather than volcanic, origin.[15]
In January, 1878, Thomas Sterry Hunt married Anna Rebecca, daughter of Mr. Justice Gale, of Montreal. She was born and educated in Montreal, Quebec. Her early years were spent on a farm adjacent to Montreal. After her father's death, in 1865, she and her two sisters,
Baroness von Friesen, and Mrs. Stuart of Quebec, travelled extensively in Europe.
The couple moved to Boston, and travelled extensively both before and after her husband's
death in February, 1892. Mrs. Hunt was a linguist, and authored volumes of poems.[17]
