Description
John Frederic Daniell (1790-1845) was an English scientist who, in 1831, became the first professor of chemistry in King’s College, London. He was also known for having devised a pyrometer that measured heat by means of the expansion of a metal bar. This Daniell pyrometer came from the U.S. Military Academy. The “J. Newman, 122 Regent Street, London” inscription refers to James Newman, an instrument maker active in the 1830s.
