Johann Urban (or Johannes Urban, 7 June 1863 – 13 November 1940) was an Austrian chemist and industrialist. He was one of the pioneers of the artificial silk industry. ==Early years== Johann Urban was born on 7 June 1863 in Wuchern near Marburg (now Maribor), Lower Styria. His father was a timber merchant. He studied mechanical and electrical engineering in Graz, and expected to work as a teacher at a state vocational school. Instead, he found work in a light bulb factory in Rotterdam, where he met Max Fremery. In the mid-1880s Urban and Fremery took over the technical management of a light bulb factory in Gelnhausen. 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 Urban」の詳細全文を読む スポンサード リンク
