Swiss-born Arnold Guyot was a geologist and geographer who made contributions to the understanding of the growth and movement of ice within glaciers and introduced pioneering methods for the teaching of geography and geology. Guyot developed a barometer for the Smithsonian Institution as well as a set of rules for making meteorological observations, and he assisted in choosing locations for weather stations. He also made exploratory trips throughout New England and the mid-Atlantic, providing detailed reports on the geology of those regions and providing accurate measurements of the height of peaks in the White Mountains and the Appalachians. He was a charter member of the National Academy of Sciences.
