An American geologist and mineralogist; Eaton ( 1776-1842) studied under Benjamin Silliman and then went to Williams College. With the aid of Stephen Van Rensselaer (1764-1839), Eaton established the Renesslaer School in Troy, New York and was with the school from 1824 until his death. That institution is known today as the Rensselaer Polytechnic Institute. His students included many of the pioneers of early American geology and paleontology including James Hall, Douglas Houghton and Ebenezer Emmons. He is best noted for his dedication to promoting the teching of geology and the establishment of the early state surveys and his early attempts to arrange the strata of the United States. His first published attempt at organizing the strata of the northeast was in his 1818 "Index to the Geology of the Northern States". His above work contains the first attempt of a geological profile along the Helderbergh in Albany County. The work was undertaken under the direction of the Agricultural Society as were many of the early studies of the geology of parts of New York State. The stratigraphy used by Eaton and Beck followed that of Maclure and they adhered to the Wernarian School in that flat-lying rocks are Secondary and therefore must be younger. In addition to the stratigraphy of the county the report contains a catalogue of the minerals found, a catalogue of the hot springs and catalogues of the soils and the rocks.
