Ruthenium was the last of the platinum metals to be discovered. In 1824, extensive alluvial deposits of native platinum were discovered in the Ural Mountains, in Russia. Very soon Russia became the main producer of that metal, developing and improving its metallurgical industry. Various scientists, such as G. W. Osann, of the University of Dopart, were in charge of the study of the insoluble residues of the platinum. He announced, in 1828, that this material contained three new elements which he named pluran, ruthen and polin. In spite of this research, some of his work was not considered by some famous chemists like Berzelius, but was inspiring to some others like K. K. Klaus leading to the discovery of ruthenium in 1844 in the University of Kazan. The name of the element was proposed by Klaus and it derives from the latin name " Russia ", major producer of these metals and in recognition of the work of Osann.
