Who identified ruthenium?: In 1808, a Polish chemist named Jedrzej Sniadecki claimed that he had identified a new element, that was probably ruthenium, but his work was not verified. In 1828, a Russian chemist named Gottfried Osann identified a new element present in a platinum ore from the Ural Mountains. He named the element ruthenium and sent samples of the ore to Jöns Jakob Berzelius. Berzelius did not agree that any new element was present in the sample. Osann publicly retracted his claim in 1829.

In 1844, Karl Klauss, working in Estonia, analysed a sample of the same platinum ore to settle the question. He managed to extract a sample of the new element. This time Berzelius had to agree that a new element had been identified. Klauss was credited with the discovery. However, he called the element ruthenium out of respect for Osann's work.

About ruthenium: Ruthenium is one of the rarest elements in the Earth's crust. It can be found in its free state (as an element) and it is usually associated with platinum and palladium ores. It is used in alloys to strengthen both platinum and palladium.
