    In September 1860, Mendeleev attended an international chemistry congress that was held to discuss critical issues as atomic weights, chemical symbols, and chemical formulas, where he met many of Europe’s leading chemists. In later years, that congress was especially remembered by Mendeleev due to an important paper circulated to the Italian chemist Stanislao Cannizzaro that explained the notion of atomic weights.

    The Unknown

    Saint Petersburg, Russia
    1860s

    In 1863, there were 56 known elements with a new element being discovered at a rate of approximately one per year, there existed almost 63 known elements by end of the 1860s. And during Mendeleev's work on organizing the existed elements according to their atomic weight, he proposed the potential of existence for new elements such as germanium, gallium, and scandium. Back then this was strongly criticized.

    Principles of Chemistry

    Saint Petersburg, Russia
    1868

    At the beginning of his teaching career as a professor, he couldn't find a textbook that satisfied his needs for his courses. So, he wrote the definitive textbook of his time, Principles of Chemistry (two volumes, 1868–1870). These books have had many editions and translations. Also, the books helped Mendeleev in his later discoveries.

    The Periodic Law

    Saint Petersburg, Russia
    Mar, 1869

    During his researches, Mendeleev discovered a dependency between the atomic number of an element and it's physical and chemical properties. So, In March 1869, Mendeleev postulated the periodic law, also called Mendeleev's law. It stated that the physical and chemical properties of the elements recur periodically when arranged in the order of their atomic weights.

    "The Father of the Periodic Table"

    1869

    In 1869, Mendeleev made his most important discovery. As he attempted to classify the elements according to their chemical properties, he noticed patterns that led him to postulate his periodic table.

    Beyond Chemistry

    Beginning in the 1870s, Mendeleev cared about fields concerning his motherland beyond chemistry, looking at aspects of the Russian industry, and technical issues in agricultural productivity. He explored demographic issues, sponsored studies of the Arctic Sea, tried to measure the value of chemical fertilizers, and promoted a merchant navy.

    Proven Right

    The lost Nobel

    Stockholm, Sweden
    1906

    In 1906, the Nobel Committee for Chemistry recommended to the Swedish Academy, at which Mendeleev was a member, to award the Nobel Prize in Chemistry for 1906 to Mendeleev for his discovery of the periodic system. The Chemistry Section of the Swedish Academy supported this recommendation. The Academy was then supposed to approve the Committee's choice, as it has done in almost every case. Unexpectedly, at the full meeting of the Academy, some members of the committee pressed for the rejection of Mendeleev, arguing that the periodic system was too old to acknowledge its discovery in 1906.
