Canada. In 1861, he was elected as a member of the American Philosophical Society. 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 Cambrian strata, were forcibly advocated. Hunt was elected a member of the National Academy of Sciences in 1873. 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. 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. He died in New York City on February 12, 1892. The Thomas-Sterry-Hunt International Ecological Reserve, an ecological reserve in Quebec, Canada was established on September 7, 1988.

She was born and educated in Montreal, Quebec. Her early years were spent on a farm adjacent to Montreal.
