Dmitri Mendeleev, 1834 - 1907, was a Russian chemist who developed the modern Periodic Table of Elements.
Periodic Table, elements, chemical properties, physics
Known as 'The Father of the Periodic Table'.
Davy Medal, 1882, Royal Society.
Copley Medal, 1905, Royal Society.
Foreign Member of the Royal Society (ForMemRS), 1892.
He was a contender for the Nobel Prize in 1906, but was ousted by what are now considered personal grudges by members of the Nobel Committee, and Mendeleev died the following year.
A crater on the Moon is named in his honour.
Mendelevium, Z = 101, A = 258), discovered in 1955, is named after him.
The National Metrology Institute in Saint Petersburg bears his name and a statue of him stands outside.
Several other institutions and place names in Moscow and other places in Russia use his name.
The Russian Academy of Sciences awards the Mendeleev Golden Medal annually (since 1998).
Professor of Chemistry at the Saint Petersburg Technological Institute (1864-) and Saint Petersburg State University (1865-1890), developing Saint Petersburg into an internationally recognised centre for chemistry research.
Director of the Bureau of Weights and Measures, 1893 - 1907.
Book on the spectroscope, 1861.
PhD dissertation "On the Combinations of Water with Alcohol", 1865.
Tentative System of Elements, a later publication of Mendeleev's original draft paper to the Russian Chemical Society on 6 March 1869, The Dependence between the Properties of the Atomic Weights of the Elements.
A Chemical Conception of the Ether, 1904, a booklet suggesting the existence of an interstellar 'ether gas' which was lighter than hydrogen, produced by the sun. (NB: the presumption of the existence of the ether was debunked by the Michelson-Morley experiment and Einstein (explaining how EMR may travel through empty space) in this period.)
Mendeleev is most famous for his development of the Periodic System of Elements, known as the Periodic Table, first published in 1869.
Predicted the properties of till then undiscovered elements. Although he used different names, the elements he successfully predicted were (year of discovery in brackets): gallium (1875), scandium (1871), germanium (1886), rhenium (1926), technetirum (1937), protactinium (1900), hafnium (1923).
Mendeleev investigated the geologic formation of petroleum, built the first oil refinery, and proposed the use of petroleum as a feedstock for petrochemicals.
Investigations into the properties of petroleum. Mendeleev helped build the first oil refinery in Russia.
Mendeleev was able to use his Periodic System to predict successfully the existence of 'missing' elements, and their expected properties.
In his paper submitted to the Russian Chemical Society on 6 March 1869, The Dependence between the Properties of the Atomic Weights of the Elements, Mendeleev describes the elements in the original classification by atomic weight and valence. He proposed 8 characteristics for the Periodic System:
Mendeleev was also a pioneer in the petrochemicals industry. He is reported to have commented: "Burning petroleum as a fuel would be akin to firing up a kitchen stove with bank notes."

1894 - 1966
Georges Lemaître, 1894 - 1966, was a Belgian astrophysicist, best known for being the originator of the Expanding Universe theory, and the Big Bang origin of the universe.
"You think the universe can’t be expanding?" Sean asked the clown-professor, Einstein.
"You don't zink an infinite universe ist big enough already? You want more zan infinite? You greedy."
