James Newbery

James Cosmo Newbery (28 June 1843 – 1 May 1895), generally referred to as Cosmo Newbery or J. Cosmo Newbery, was a United States-educated Australian museum administrator and industrial chemist, and co-developer of the Newbery-Vautin chlorination process for gold extraction.

Newbery was the fourth son of William Boxer Newbery, born near Livorno, Grand Duchy of Tuscany. When quite young he emigrated to the United States of America, and ultimately graduated as Bachelor of Science at Harvard University.

After leaving Harvard, Newbery studied at the Royal School of Mines, Jermyn Street, London, and in 1865 was appointed analyst to the Geological Survey of Victoria—an appointment which he held until 1868, when the department was abolished.
