Heinrich Rose (6 August 1795 – 27 January 1864) was a German
mineralogist and analytical
chemist. He was the brother of the mineralogist
Gustav Rose and a son of
Valentin Rose.[1]
Rose's early works on phosphorescence were noted in the
Quarterly Journal of Science in 1821,[2] and on the strength of these works, he was elected privatdozent at the
University of Berlin from 1822, then Professor from 1832.[3]
In 1846, Rose rediscovered the
chemical elementniobium, proving conclusively that it was different from
tantalum. This confirmed that
Charles Hatchett had discovered niobium in 1801 in
columbite ore. Hatchett had named the new element "columbium", from the ore in which niobium and tantalum coexist. The element was eventually assigned the name niobium by the IUPAC in 1950 after
Niobe, the daughter of
Tantalus in
Greek mythology.[4][5][6][7][8][9][10]
In 1845, Rose published the discovery of a new element
pelopium, which he had found in the mineral
tantalite.[11] After subsequent research, pelopium was identified to be a mixture of tantalum and niobium.[12]
