Karl Ernst Claus, also known as Karl Klaus or Carl Claus (Russian: Карл Ка́рлович Кла́ус, romanizedKarl Karlovich Klaus; 22 January 1796 – 24 March 1864),[1] was a Russian chemist and naturalist of Baltic German origin. Claus was a professor at Kazan State University and a member of the Russian Academy of Sciences. He was primarily known as a chemist and discoverer of the chemical element ruthenium, which he named after his homeland of Russia,[2][3] but also as one of the first scientists who applied quantitative methods in botany.[4][5][6]
