James Freeman Dana (born in Amherst, New Hampshire, 23 September 1793; died in New York City, 14 April 1827) was an American chemist.
He studied with Dr. John Gorham, and developed such ability that in 1815 he was selected by the authorities of Harvard to procure for the chemical laboratory a new outfit of apparatus.
For this purpose, he visited London, where for six months he worked in the laboratory of Friedrich Christian Accum.
[2] On his return to the United States he settled in Cambridge, where he practised medicine and was appointed assistant to the chair in chemistry.
He contributed numerous scientific memoirs to Silliman's American Journal of Science and to the Annals of the New York Lyceum of Natural History.
