bio: |
  Born 5 June 1760, Gadolin became a chemist, physicist, and mineralogist in Finland when those borders and disciplines were still taking shape. He took the second Chair of Chemistry at the Royal Academy of Turku and built Finnish chemistry research from nearly nothing. The work that mattered came from a mineral sample: he isolated a "new earth" that turned out to contain yttrium, the first rare-earth compound anyone had identified. The find eventually led to an entire family of elements. He was ennobled for it and given the Order of Saint Vladimir and the Order of Saint Anna. He died 15 August 1852, having widened the map.
