Дэвид Томас Анстед: Англиялық геолог және жазушы өмірі мен еңбектері

English geologist and author

David Thomas Ansted FRS (5 February 181413 May 1880) was an English professor of geology and author of numerous books on geology. His role as a teacher at Addiscombe Military Seminary, where future East India Company army officers were trained, had an influence on the study of geology in the colonies.

Ansted was born in London on 5 February 1814 to William Ansted. He was educated at Jesus College, Cambridge, and inspired by Adam Sedgwick took an interest in geology. After taking an M. A. degree in 1839, he was elected to fellow of the college. He was appointed professor of geology at King's College London in 1840, holding the post until 1853. From 1845, he was also a lecturer at the East India Company's Military Seminary at Addiscombe (until its closure in 1861), and professor of geology at the College for Civil Engineers at Putney. He became a fellow of the Royal Society in 1844, and from that date until 1847 he was vice secretary of the Geological Society. The practical side of geology now came to occupy his attention and he visited various parts of Europe as a consulting geologist and mining engineer.

Ansted's Gold Seekers Manual (1849) attempted to improve the prospects of emigrants to the California gold rush. His other published works include Geology, Introductory, Descriptive, & Practical (1844), The Geologist's Text Book (1845), Syllabus of Lectures on Mineralogy, Geology, and Practical Geology (1848), An Elementary Course of Geology, Mineralogy, and Physical Geography (1850), The Great Stone Book of Nature (1853), The Applications of Geology to the Arts and Manufactures (1865). He was the co author with Robert Gordon Latham of The Channel Islands (1862). By 1853, Ansted's reputation was sufficient that he was hired by potential investors to survey promising coal fields along the New River in southern Virginia in the United States, and he was one of the earlier geologists to identify the rich bituminous coal seams which lay there. Ansted collaborated with numerous scientists of the period and like many others he entered into a correspondence with Charles Darwin in about 1860.

Ansted married Augusta Dorothea Hackett (1828 1897), daughter of Alexander Baillie on 24 June 1848 and they had six children. Ansted died at Melton near Woodbridge, Suffolk, on 13 May 1880.
