Stas, JS (English spelling) StasJS

…The analytical chemist's duties, in addition to ordinary analysis, included, especially after the Karlsruhe Congress, the precise measurement of atomic weights. In this field, the contributions of Jean Servais Stas (1813-91), T. W. Richards, and others after Berzelius were notable.
[20th century]
Just as the 19th century chemistry began with a flourish with the discovery of the voltaic pile in 1800, the 20th century chemistry was marked by three discoveries at the end of the 19th century: the discovery of X-rays (1895), the discovery of the electron (1897), and the discovery of radioactivity (1898).

From [Richards]

…After a year of studying abroad, he became an assistant professor in analytical chemistry at Harvard University, and in 1901 became a professor. He made various improvements to the gravimetric analysis method, precisely measuring the atomic weights of many elements, and corrected the values ​​used by Jean Servais Stas (1813-91), which had been in use until that time. For this achievement, he was awarded the Nobel Prize in Chemistry in 1814, the first American to do so. …

…分析化学者の任務には通常の分析のほか,とくにカールスルーエの国際会議以降は原子量の精密測定が含まれるようになった。この分野においてベルセリウス以降,スタスJean Servais Stas(1813‐91),T.W.リチャーズらの寄与が目立った。
[20世紀]
 19世紀の化学が1800年のボルタ電堆の発見によって華々しく幕を開けたのと同様に,20世紀の化学はX線の発見(1895),電子の発見(1897),放射能の発見(1898)という19世紀末の三つの発見によって特徴づけられた。…

【リチャーズ】より

…1年間の海外留学ののち,ハーバード大学の分析化学の助手となり,1901年教授となった。重量分析法にさまざまな改良を加えて多数の元素の原子量を精密に測定し,当時まで採用されていたスタスJean Servais Stas(1813‐91)の値を訂正した。この功績により,14年アメリカ人として最初のノーベル化学賞を受けた。…
