Dmitri Ivanovich Mendeleev [b] (/ ˌ m ɛ n d əl ˈ eɪ ə f / MEN-dəl-AY-əf; [2] [c] [a] 8 February [O.S. 27 January] 1834 – 2 February [O.S. 20 January] 1907) was a Russian chemist known for formulating the periodic law and creating a version of the periodic table of elements.
Dmitri Mendeleev (1834–1907) [70] Arranged the sixty-six elements known at the time in order of atomic weight by periodic intervals (1869). Physical chemistry: Mikhail Lomonosov (1711–1765) The first to read lectures in physical chemistry and coin the term (1752). Jacobus van 't Hoff (1852–1911)
March 6 – Dmitri Mendeleev makes a formal presentation of his periodic table to the Russian Chemical Society. June 15 – John Wesley Hyatt patents celluloid , in Albany, New York . July 15 – Hippolyte Mège-Mouriès files a patent for margarine (as oleomargarine ) in France as a beef tallow and skimmed milk substitute for butter.
The following year the Moscow Industrial School would be renamed as the Moscow Chemical Technical College, and later, in 1919, it was given the name of the famous Russian chemist Dmitri Mendeleev. At that time, the Moscow Chemical Technical College was mostly training practical engineers. [17]
The medal has been awarded to multiple individuals in the same year: in 1882, for example, it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; [6] in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; [6] in 1893 to Jacobus ...
Gallium is discovered spectroscopically by French chemist Paul Emile Lecoq de Boisbaudran. Later in this year he obtains the free metal by electrolysis of its hydroxide and names it. This is the first of Dmitri Mendeleev's predicted elements to be identified. [1] [2] [3] Phenylhydrazine is discovered by Hermann Emil Fischer. [4]
Pyrocollodion is a smokeless powder invented by Dmitri Mendeleev. A variant of the nitrocellulose family of compounds, it was discovered by Dmitri Mendeleev in 1892. He had proposed its use as a replacement for gunpowder in the Russian Navy. This offer was rejected because of cost and efficiency considerations.
Clemens Alexander Winkler (December 26, 1838 – October 8, 1904) was a German chemist who discovered the element germanium in 1886, solidifying Dmitri Mendeleev's theory of periodicity. Life [ edit ]
