The periodic system, which Dmitri Ivanovich Mendeleev presented to the science community in the fall of 1870, is a well-established tool frequently used in both pedagogical and research settings today. However, early reception of Mendeleev’s periodic system, particularly from 1870 through 1930, was mixed. In Early Responses to the Periodic System, Masanori Kaji, Helge Kragh, and Gábor Palló explore these reactions in eleven different countries and one region.
