Mendeleev was the inventor of the periodic table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence â¦ of elements that had not yet been discovered based on gaps in the table he created.
Note the date, 17 February 1869. Other people, like Londoner John Newlands, Frenchman Alexandre Bguyer de Chancourtois and German Julius Lothar Meyer made important contributions to the first Periodic Table but the main credit goes to Mendeleev.
