Tarix
Jędrzej Śniadecki isolated the element in 1807, but his work was not ratified.
Jöns Berzelius and Gottfried Osann nearly discovered ruthenium in 1827.
In 1844, Karl Ernst Claus confirmed that there was a new element and isolated ruthenium from the platinum residues of the rouble production while he was working in Kazan University, Kazan.
