Abstract. Karl Karlovich Klaus (also known as Carl Ernst Claus) (1796–1864) was born in Dorpat, Russia (now Tartu, Estonia). He was a professor at the universities of Dorpat and Kazan, Russia. He discovered the last of the six platinum metals, which he named ruthenium in honor of Russia. His life and career are discussed along with earlier efforts of others to find this elusive element.roscopy, and comment on the purity of the final sample. The use of unknowns increases students’ individual responsibility and prevents using a partner’s data analysis.
