Samuel Eyde

Japanese: エイデ（英語表記）Samuel Eyde

1866‐1940
A Norwegian mechanical engineer. In 1903, together with C. Birkeland, a professor at the University of Christiania (now Oslo), Norway, he developed the Birkeland-Eide process, which produces nitric acid by high-temperature air discharge in a magnetic field, and was the first to successfully fix nitrogen from the air in a practical manner. In 1905, thanks to the efforts of Eide and others, this process was industrialized on a large scale at the Notodden works of the Norwegian Hydroelectric Fertilizer Company, and the nitric acid produced was eventually sold for use as fertilizer in the form of calcium nitrate salt (Norwegian saltpeter).

ノルウェーの機械技師。1903年に，同国クリスティアニア(現，オスロ)大学教授C.ビルケランとともに，磁場内での高温空中放電で硝酸を製造する〈ビルケラン=エイデ法〉を確立し，初めて実用的な空中窒素の固定に成功した。05年には，エイデらの努力により，ノルウェー水力電気肥料会社ノートデン製造所でこの方法が大規模に工業化され，作られた硝酸は最終的に硝酸カルシウムの塩(ノルウェー硝石)の形で肥料用に販売された。
