Dmitri Mendeleev (1834 – 1907) was a Russian chemist . He created the first version of the periodic table of elements, and used it to predict the properties of elements yet to be discovered. Using his periodic table, Mendeleev predicted the existence and properties of new chemical elements. When these elements were discovered, his place in the history of science was assured. He died in Saint Petersburg, February 2, 1907, six days before his 73rd birthday. He was killed by influenza.
