Dr. John Augustus Just (January 9, 1854 – September 13, 1908) was a German-born chemist and inventor. He is best known for his investigative work into recovery of precious metals from their ores and for completing the process for evaporating milk. For his scientific achievements, he was awarded a medal by the committee celebrating Berthelot’s 50th anniversary. Just registered dozens of patents with the United States Patent Office. He also founded several companies in the Syracuse, New York area including the Just Mining and Extraction Company, the Just's Food Company, the Just Process Company and the Just Reduction Company. He belonged to numerous scientific societies, and his work in investigative chemistry gained him worldwide recognition. ==Early life and education== John Augustus Just claimed to have been born in Karlsbad, Germany; United States census records, however, indicate that he was born in the small town of Feilbingert in the state of Rhineland-Palatinate, Germany. He was one of five children. Their parents were Christian and Julia (Steel) Just; Christian was a merchant, interested in coal-mining. Little is known about Just's early years; William Martin Beauchamp wrote that "John A. Just from early boyhood days manifested the strong mentality and love of scientific research which have gained him eminence as a chemist".〔Beauchamp, William. ''Past and Present of Syracuse and Onondaga County'', Volume II. 1908; p. 486.〕 He attended German public schools, Bonn University, the technology school at Zurich and Heidelberg University (from which he graduated as Doctor of Science at age 18). Immediately after graduation Just emigrated to New York following the war between Germany and France, leaving Antwerp in the spring of 1874 and arriving in New York shortly afterwards. Upon his arrival he lived in New York City for 13 years, working as a chemist for a large corporation. He continued to study chemistry at the Astor Library. 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「John Augustus Just」の詳細全文を読む スポンサード リンク
