Newlands

British chemist. He entered the Royal College of Chemistry in 1856 to study under AW Hoffmann, and after serving as assistant chemist at the Royal Agricultural Society, he became independent as an analytical chemist in 1864. From 1868, he worked as a chemist at a sugar refinery. In 1860, as his mother was of Italian descent, he temporarily joined Garibaldi's volunteer army and participated in the Italian unification movement. In 1864, he attempted to classify elements based on the integer (ordinal number) obtained by dividing the atomic weight of an element by a constant and the similarity of the element's properties. The following year, in 1865, he proposed the octave law, which states that if all 62 elements known at the time are arranged in order of ordinal number, elements with similar properties are arranged at every ordinal difference of 7, but this was not accepted. However, after DI Mendeleev's discovery of the periodic law (1869), he claimed priority of discovery and was recognized, and in 1887 he was awarded the Davy Medal by the Royal Society.

イギリスの化学者．1856年王立化学カレッジに入学してA.W. Hoffmann(ホフマン)に学び，王立農業協会で化学者助手を務めたのち，1864年分析化学者として独立した．1868年からは，砂糖の精製所に化学者として勤めた．1860年母がイタリア系だったので，ガルバルディの義勇軍に一時加わり，イタリア統一運動に参加した．1864年元素の原子量を定数で割って得られる整数(順序数)と元素の性質の類似から，元素の分類を試みた．翌1865年，当時の既知の全元素62を順序数の順に並べると，順序数差7ごとに性質の似た元素が並ぶというオクターブの法則を提唱したが受け入れられなかった．しかし，D.I. Mendeleev(メンデレーエフ)の周期律発見(1869年)後，発見の優先権を主張して認められ，1887年ロイヤル・ソサエティよりデイビー・メダルを贈られた．
