Dmitri Mendeleev

About Dmitri Mendeleev

Dmitri Mendeleev (1834–1907) was a foundational figure in chemistry, best known for formulating the Periodic Law and creating his own comprehensive version of the periodic table of elements. His genius lay in leaving gaps within his early table, correctly predicting the properties of elements not yet discovered, such as gallium and germanium. This predictive power and his systematic organization of chemical knowledge solidified his place, earning him an HPI Rank of #259 among history's most influential people.

Compared to his historical importance, Mendeleev's contemporary digital footprint is modest. In 2025, his Wikipedia page accrued approximately 396K annualized views. This level of attention is comparable to his historical importance (an Attention Gap of ~1x), placing him in a less extreme category than figures who are either vastly over- or under-represented. For context, he receives significantly fewer views than figures from a similar modern era, such as Helen Keller (#917 importance, 2.6M views), suggesting that while not entirely forgotten, his foundational chemical contributions do not capture the general public's immediate internet curiosity.

His current online trajectory shows a slight waning of interest, with a Year-over-Year change of -2.6% and a sharper decline in engagement from Q1 to Q3, evidenced by a -42% momentum score, indicating that his relevance is slowly receding in the current digital landscape.
