ヴィルヘルム・ヴェーバー
From 1857 to 1859 Christie had studied in Göttingen under Wilhelm Eduard Weber. Among others, he measured diamagnetism in bismuth. He also studied in Paris under Henri Victor Regnault. The work on diamagnetism in bismuth was his only published thesis, but he became known for his textbooks in physics. He released a textbook for the university level, in two volumes in 1864 and 1865, and a textbook for upper secondary schools in 1871. The latter was translated to both Swedish and Finnish. He was a subeditor for the journal "Polyteknisk tidsskrift" from 1855 to 1857, and from 1855 to 1856 he was the chairman of the Norwegian Polytechnic Society.
