        Design by Dmitri Mendeleev, a Russian, and Lothar Meyer, a German, who independently, and almost
        simultaneously, came up with the same way of organizing the chemical elements. Mendeleev is generally
        given more credit, since he was bold enough to use his table to predict the properties of elements yet to be

        The table gets a big twentieth century helping hand from Henry G.J. Moseley, a 26 year old graduate
        student of Rutherford's in 1913, who discovered a way to use x-rays to measure the nuclear charge (the #
        of protons in an atom). This led to the 20th century discovery that the elements in the table are organized
        by the number of protons (atomic number). Tragically, Moseley was killed the next year in World War I.
