Emmanuel Geoffroy (1862 December 12, Saintes–1894) was a French botanist and explorer. Geoffroy traveled to Martinique and French Guiana in search of latex-yielding trees, but also studied the region's native plants in the genus ''Robinia'' after learning that forest Indians of French Guiana used ''Robinia'' as fish poisons. One in particular, "''Robinia''" ''nicou'', which is now considered to be ''Lonchocarpus nicou'', was to be the subject of his thesis, (フランス語:Contribution à l'étude du Robinia Nicou Aublet au point de vue botanique, chimique et physiologique). In a fact to be discovered posthumously, Geoffroy unknowingly discovered rotenone, which he originally named ''nicouline''.〔 He died in 1894 as a result of a parasitic disease.〔(【引用サイトリンク】 publisher=ASNOM )〕 ==References== * * 〔 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「Emmanuel Geoffroy」の詳細全文を読む スポンサード リンク
