Adolph Theodor Kupffer ForMemRS (17 January 1799 Jelgava - 4 June 1865) was a German-Baltic (subject of Russian Empire) chemist, and physicist. He founded the Depot of Standard Weights and Measures, and the main physical Observatory in Russia.〔http://learnedrussian.com/biography-of-adolf-kupffer-efron.html〕 ==Life== He studied at the school in Mitau, and discovered an interest in science, graduating in 1813. He graduated from the University of Dorpat in 1816 and studied mineralogy with the Christian Samuel Weiss in Berlin. After the Berlin University, he studied in Paris and Göttingen, where he received his PhD. Arriving in St. Petersburg, Kupfer was called to the chair of chemistry and physics at Kazan, and was sent by the Ministry of Education abroad for the purchase of physical instruments, where he went to Professor Ivan Simonov. In 1824, he arrived in Kazan and took his chair. Simultaneously, he worked on terrestrial magnetism, and magnetic charge of the geological expeditions in the vicinity of Mount Elbrus. Since 1828, he was a member of the Academy of Sciences of Mineralogy, and from 1840 in physics. In 1828, he traveled to the South and Middle Urals. He visited Zlatoust, Miass, and Chelyabinsk. After seeing the Ural Mountains in the vicinity of Zlatoust, he identified three mountain ranges: Urenga, Taganay, and Yurmu. In 1833, he published a book in French, compiled from the diaries he kept during the Urals travel, ''Journey to the Urals, undertaken in 1828.'' In 1834, a copy of this book was presented to Emperor Nicholas I. In 1829, Kupfer traveled to the Caucasus, and was later appointed director of the Mineralogical Museum, and founded the St. Petersburgs Observatory, which focused on meteorological observations throughout the empire. Kupfer offered a plan to introduce a unified system of measures throughout Russia; he was Chief Executive of the Commission on Weights and Measures from 1832 to 1842. He led the development of Russian system of measures, and creation of the first standard units of mass and length, the platinum pounds and yards, as well as exemplary volume measures - buckets and the quadrangle. The results of his works were legitimized imperial decree in 1835, and they are described in the ''Travaux de la Commission pour fixer les mesures et les poids etc.'' (St. Petersburg, 1841). In 1843 he was elected ordinary academician. In 1859, he represented Russia at the Congress of the International Association for the introduction of a uniform system of measures, weights and coins in Bradford. Beginning in 1857, Russia and France began to exchange meteorological data. Kupfer went to the negotiations abroad, and in winter 1865, he arranged a telegraphic communication between all European countries. In fact, combining the weather service, Kupfer did not have time to enjoy the fruits of their labor. In March the cold setting on the roof of the observatory brought from Paris anemograph (anemograph), he caught cold and died of pneumonia on 4 June 1865. He was buried in Smolensky Lutheran Cemetery St. Petersburg. 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「Adolph Theodor Kupffer」の詳細全文を読む スポンサード リンク
