• Resumen

  • It has been asserted that as many as six persons should be regarded as "co-discoverers" of the Periodic Law (of the Chemical Elements), but it is also generally acknowledged that their respective contributions were not equal. The prevalent consensus recognizes D. I. Mendeleev's contribution as preeminent, but there is considerable disagreement about the merits of the contributions by J. L. Meyer, J. A. R. Newlands, and others. By the analysis presented in the article, the "system" proposed by Meyer in 1864 must be regarded as superior to Newlands', although Mendeleev himself did not agree with that assessment. In 1912-14 Moseley made a very significant experimental and theoretical contribution to the question, and he has a more valid claim to be regarded as a "co-discoverer" than any of Mendeleev's contemporaries.
