Mendeleev
Periodic table creator
Mendeleev refers to Dmitri Mendeleev, the Russian chemist who created the periodic table of elements in 1869.
His arrangement of elements by atomic weight revealed patterns in their properties and famously predicted elements not yet discovered.
Mendeleev's periodic table remains foundational to chemistry, though modern versions arrange by atomic number rather than weight.
