Heinrich Rose (1795-1864), German chemist. Born in Berlin, Rose was appointed a professor (1823) and then Chief Chemical Chair (1835) at the University of Berlin. An eminent analytical chemist, his standard treatise on chemical analysis has gone through seven editions in Germany, and has been translated into both English and French. In 1844, Rose demonstrated that niobium (columbium) and tantalum, which had similar properties, could be isolated from each other, and were two different elements. This resolved the controversy of whether they were the same element. Portrait published in 1860.
