The Oechsle scale, named after him and divided into degrees Oechsle (°Oe), is still used for official classification of German wine, Swiss wine and Luxembourg wine. ==Biography== Oechsle was born in Buhlbach at Baiersbronnin the northern part of the Black Forest area, the son of Israel Oechsle, a master glass blower, and Christina Juditha Lieb.〔 As a boy, he went to school there. Towards the end of the 1780s he was apprenticed to a goldsmith and jeweller in Öhringen (Württemberg), followed by some itinerant years. In 1800 he became a master cabinet maker at a juwelery factory in Pforzheim. In 1810 he founded a mechanical workshop in Pforzheim and among other things manufactured precision beam balances and physical and hydrostatic equipment for laboratories and universities, as well as musical instruments. In 1820 the Grand Duchy of Baden appointed him official gold inspector. In 1829 he developed a safe oxyhydrogen equipment for soldering, and was at this time also operating a liquor distillery. Oeschle died in Pforzheim, aged 77. 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「Ferdinand Oechsle」の詳細全文を読む スポンサード リンク
