1767‐1813 Swedish chemist and mineralogist. Born in Stockholm, he studied at Uppsala University, where he later became professor of chemistry. In 1795, he was the first to introduce to Sweden a new system of chemical nomenclature based on Lavoisier's system. In 1797, he anonymously published a detailed study of the newly discovered element yttria, an oxide, and in 1802 he discovered the new element tantalum. This was confused with columbium (niobium), discovered the previous year, but it was not until 1846 that it was confirmed to be a different element.
