Johann Gottlieb Gleditsch (5 February 1714 in Leipzig – 5 October 1786 in Berlin) was a German physician and botanist known for pioneer investigations of plant sexuality and reproduction. He studied medicine and other subjects at the University of Leipzig (1728–35), where one of his instructors was naturalist Johann Ernst Hebenstreit (1703–1757). From 1742 he gave lectures in physiology, botany and materia medica at the University of Frankfurt, afterwards relocating to Berlin as a professor of botany at the ''Collegium Medico-chirurgicum'' and director of the local botanical garden. Beginning in 1770, he gave lectures at the recently established institute of forestry, where he was instrumental in providing a scientific basis for the field of forestry.〔(ADB: Gleditsch, Johann Gottlieb ) @ Allgemeine Deutsche Biographie〕 In his experiments involving plant movement, he demonstrated the influence that climatic factors had upon plant organs. Also, his views on the role that insects play in pollination of plants was considered to be ahead of its time.〔(Deutsche Biographie )〕 The botanical genus ''Gleditsia'' (family Fabaceae) is named in his honor,〔(Missouri Botanical Garden ) Gleditsia triacanthos〕 as is the botanical journal "Gleditschia".〔(WorldCat Title ) Gleditschia〕 In Berlin-Schöneberg, a thoroughfare called ''Gleditschstraße'' bears his name. == Selected works == * "Consideratio Epicriseos Siegesbeckianae in Linnaei Systema Plantorum Sexuale Et Methodum Botanicam Huic Superstructam", 1740 - dissertation in which Gleditsch recognized the importance of the Linnean System. * "Systema plantarum a staminum situ Systema plantarum a staminum situ", 1764. * ''Vermischte physicalisch-botanisch-oeconomische Abhandlungen'', 1765 - Mixed physical-botanical-economic treatises.〔(Open Library ) (publications)〕 * ''Systematische Einleitung in die neuere, aus ihren eigenthümlichen physikalisch-ökonomischen Gründen hergeleitete Forstwissenschaft'' (two volumes, 1775) - Systematic introduction to the newly (due to unique physical-economic reasons) derived forestry.〔 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「Johann Gottlieb Gleditsch」の詳細全文を読む スポンサード リンク
