Gustav Ferdinand Richard Radde (27 November 1831 - 2 March 1903) was a German naturalist and explorer. ==Biography== Radde was born in Danzig, the son of a schoolmaster. He had little formal education, and began a career as an apothecary. He became increasingly interested in natural history, and in 1852 he gave up his career and spent two years in the Crimea with the botanist Christian von Steven, collecting both plants and animals. He made further trips to southern Russia with Johann Friedrich von Brandt and Karl Ernst von Baer. He was botanist and zoologist on the East Siberian Expedition of 1855, led by the astronomer Ludwig Schwarz. In 1864 he eventually settled in Tbilisi. In the same year he explored the region surrounding Mount Elbrus, the highest mountain in the Western Palearctic. As well as collecting many plants he recorded the languages, ballads and customs of the local tribes. He set up a museum (the Caucasus Museum) and library in Tbilisi to exhibit his discoveries. His collecting expeditions included visits along the Black Sea coast and eastwards beyond the Caspian Sea to Askhabad. In 1895 he sailed to India and Japan with the Grand Duke Michael, and two years later he was official naturalist on a visit by members of the Russian imperial family to North Africa. He eventually became a member of the Council of State in Tiblisi. In 1884 he was honoured with the chairmanship of the first International Ornithological Congress in Vienna. He was also an honorary member of the D. O.-G., and a foreign member of the British Ornithologists' Union and the Zoological Society of London. He was awarded the Patron's Gold Medal of the Royal Geographical Society in 1889 and the Constantine Medal of the Imperial Russian Geographical Society in 1898. 〔 (【引用サイトリンク】 title= OBITUARY.
