George Frederick Kunz (September 29, 1856 – June 29, 1932) was an American mineralogist and mineral collector. ==Biography== Kunz was born in New York City, USA, and began an interest in minerals at a very young age. By his teens, he had amassed a collection of over four thousand items, which he sold for four hundred dollars to the University of Minnesota. Kunz attended Cooper Union but did not finish and did not attend college. Nonetheless, he taught himself mineralogy from books and field research. This expertise landed him a job with Tiffany & Co., and his knowledge and enthusiasm propelled him into a vice presidency by the time he was 23. He gained much notoriety for identifying a new gem variety of the mineral spodumene which was named "Kunzite" in his honor. He headed up the US mining and mineralogical exhibits at the international expositions in Paris (1889), Chicago (1893), Atlanta (1895), Paris (1900), and St. Louis (1904). He gave a series of eight lectures on "Precious Stones" for the Lowell Institute's 1894-95 season.〔Harriet Knight Smith, (''The history of the Lowell Institute'' ), Boston: Lamson, Wolffe and Co., 1898.〕 As a gentleman scientist, he was a member of the Mineralogical Society of America, the American Association for the Advancement of Science, New York Academy of Sciences (of which he was once a vice president), the New York Mineralogical Club, the American Scenic and Historic Preservation Society (for which he served as president), the American Chemical Society, the American Institute of Mining and Metallurgical Engineers (of which he was once a vice president), and many other cultural, scientific, and naturalist organizations. He was the founder and president of the Museums of the Peaceful Arts in 1913, special agent for the US Geological Survey (1883–1909), a research curator at the Museum of Natural History in New York City, and the leading advocate in the establishment of the international carat as a unit of measure for precious gems. He also assembled the Morgan-Tiffany collection of gems in the American Museum of Natural History. Kunz had an active life dedicated to science and public service. Kunz promoted the adoption of the decimal metric system of weights and measures in the United States and was President of the American Metric Association.〔George Kunz, "The International Language of Weights and Measures," ''The Scientific Monthly'', vol. 4, 1917, pp. 215-219.〕 He wrote over 300 articles during his life. Almost eighty years after his death, many of his books are still in print. Kunz married Sophia Hanforth in 1879, who died in 1912. In 1923, Kunz married Opal Logan Giberson, a noted aviatrix, but soon annulled the marriage. Nonetheless, Opal Kunz continued to maintain Kunz's household until his death, on June 29, 1932. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「George Frederick Kunz」の詳細全文を読む スポンサード リンク
