Periodic table (detailed cells)
Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869. Mendeleev invented the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.
Hugo Stintzing
In 1916 he proposed a model for the periodic table, organized as a cone-like rotational body. His paper, "Eine neue Anordnung des periodischen Systems der Elemente" (A new arrangement of the periodic system of the elements) was published in "Zeitschrift für Physikalische Chemie". His representation of the elements is one of several early helix-based displays.
