Overview

We are all familiar with the layout of the long-standing Periodic table, as well as the distribution of its constituent elements, but who discovered them, and when? 2019 was named the International Year of the Periodic Table of Chemical Elements by UNESCO, celebrating 150 years since the invention of this remarkable tool.

In celebration of its landmark status and the event of its 150th anniversary, this visualization illustrates a revisitation of the original Periodic table, focusing on the scientists who discovered the elements – adding visual value to the story of this tool, from its inception in 1250, right up until today. The data visualization was produced for a column titled, ‘Visual Data’, and published in issue #378 of La Lettura – the cultural supplement of the Italian newspaper Corriere della Sera.
