DESCRIPTION:

Periodic Table Day marks the anniversary of the publishing of the first periodic table of elements by English chemist John Newlands, February 7, 1863. His is distinctive because he was the first to categorize elements based upon atomic mass. Newlands' however, wasn't what we're familiar with today. That format would be created by Russian Dmitri Mendeleev in 1869. He is the man who organized the tables in columns and rows based upon their atomic weight and the occasions of repetition of base elements.

Like most science, the periodic table is an international affair. To reach the point of Newlands and Mendeleev, contributions from the French (1789, 1857, 1862) and Germans (1829, 1843) would add to the final product of an Englishman and a Russian. This event was first observed by David T Steineker.
