After studying medicine in Albany and
practising as a physician, Ebenezer Emmons
(1799-1863) returned to his first love: geology. In 1833,
he became professor of natural history of Williams College and
in 1836 was appointed Geologist-in-Chief of the
Northern District of the Geological Survey of New York State.
It was Emmons who named the "Adirondacks" (1838) and "Taconic
Mountains" (1844). In the course of his career, Emmons argued
that oldest stratified fossil-bearing rocks on the continent were
not Silurian but Taconic, or Upper Cambrian. This position was
controversial and led to friction with eminent geologists such as James
Hall.
Emmons' major work is entitled American Geology (1855-57) , a theoretical treatise with
illustrations
of characteristic American fossils. Emmons made contributions on agriculture and
geology in several volumes of the Natural History of
New York . In later life, Emmons serves as state geologist of
North Carolina (1851-60) and conducted a geological survey of that
state. According to Jules Marcou, Emmons was “the founder of
American palaeozoic stratigraphy." |
