Dmitri Mendeleev
Dmitri Ivanovich Mendeleev (/ˌmɛndəlˈeɪəf/; Russian: Дми́трий Ива́нович Менделе́ев; IPA: [ˈdmʲitrʲɪj ɪˈvanəvʲɪtɕ mʲɪndʲɪˈlʲejɪf]; 8 February 1834 – 2 February 1907 O.S. 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.
