Jöns Jacob Berzelius


  He was a Professor of chemistry and medicine at the Stockholm medical school who discovered selenium and ceria, and isolated silicon, thorium, and zirconium. Berzelius accurately determined the atomic weights of elements known at that time, necessary for the development of the Periodic Table. Berzelius produced many famous scientists - Wöhler, Rose, Mosander, Sefström, and Arfwedson.
