Biography
Dmitri Ivanovich Mendeleev(8 February 1834 – 2 February 1907)
was born in the village of Verkhnie Aremzyani, near Tobolsk. At
the age of 16, Dmitri moved to Saint Petersburg and won a place
at his father’s old college. In 1855, aged 21, he got a job teaching
science in Simferopol, but soon returned to St. Petersburg. There
he studied for a master’s degree in chemistry at the University of
St. Petersburg. He was awarded his degree in 1856.
In 1867, aged just 33, he was awarded the Chair of General
Chemistry at the University of Saint Petersburg. In this prestigious
position he continued pushing to improve chemistry in Russia,
publishing The Principles of Chemistry in 1869.

Periodic table
The breakthrough came early in 1869, as Mendeleev was preparing
for another industrial tour – this time to investigate and improve
cheese-making techniques. Meanwhile, having completed the first
volume of his textbook, he was struggling to establish a framework
for the second. He later recalled the process as follows:
’So I began to look about and write down the elements with their
atomic weights and typical properties, analogous elements, and like
atomic weights on separate cards, and this soon convinced me
that the properties of the elements are in periodic dependence upon
their atomic weights…’

Periodic table(pt.2)
On the 6th of March 1869 the first rough sketch of his table was presented to the Russian
Chemical Society. Later that year the society’s journal published a more considered
version, a short abstract of which appeared in German translation. It attracted little
attention outside Russia but Mendeleev persevered, continuing to lay out more cards on
his table.

Other achievements
Mendeleev was one of the founders, in 1869, of the
Russian Chemical Society. He worked on the theory
and practice of protectionist trade and on agriculture.
Mendeleev devoted much study and made important
contributions to the determination of the nature of
such indefinite compounds as solutions.
Mendeleev is given credit for the introduction of
the metric system to the Russian Empire.
He invented pyrocollodion, a kind of smokeless
powder based on nitrocellulose.
