Frederick Field (2 August 1826 – 3 April 1885) was an English chemist. Early life He was born in Lambeth, London, the second son, by his second wife, of Charles Field, of the firm of J. C. & J. Field, candle manufacturers, etc. Educated at Denmark Hill grammar school and at Mr. Long's school at Stockwell (where he was a schoolfellow of Professor Odling), Field showed so strong a liking for chemistry that, on leaving school in 1843, he was placed in the laboratory of the Polytechnic Institution, then conducted by Dr. Ryan. On leaving the Polytechnic, Field entered into partnership with a chemist named Mitchell as an assayer and consulting chemist, but finding the need of further training spent some time as a student under Dr. Hoffmann in the Royal College of Chemistry in Oxford Street. Field was one of the original members of the Chemical Society of London, started in 1846, and he read his first paper to that society in the following year. Work in Chile In 1848 he accepted the post of chemist to some copper smelting works at Coquimbo in Chile. Some account of his work there is contained in his papers in the ‘Journal of the Chemical Society’ for 1850, 'On the Examination of some Slags from Copper-smelting Furnaces,’ and 'On the Ashes of the Cactus-plant,’ from which large quantities of carbonate of soda were obtained. In 1851 Field described a natural alloy of silver and copper, which had the appearance of nearly pure silver, and also discovered that a certain ore which occurred in large quantities near Coquimbo was in reality pure lapis lazuli, the first found in South America. In 1852 Field was appointed manager of his company's works at Caldera, a new port to the north of Coquimbo. Before assuming this position he visited England and married a sister of (Sir) Frederick Abel, returning to Caldera in 1853, of which he was now appointed vice consul. The post involved many responsibilities in a land subject to revolutions. During the Russian War, Field also acted as the representative of France in that district. In 1856 Field became chemist and sub-manager to the smelting works then established by Señor Urmeneta at Guayacan, which have since become one of the largest copper-smelting works in the world. In 1859 a revolution broke out in Chile. Field sent his wife and family to England, but himself
