It is perhaps a small consolation that he had, in his lifetime, officially entered the term "periodic" into the Chemistry lexicon. He managed to overcome the Tellurium-Iodine problem and successfully placed Thallium, Lead, Mercury and Platinum into the right groups - something Mendeleev failed to do on his first attempt.
Without one, he could only offer particulars about specific building blocks of matter, but no framework that would explain the relationships between different substances. As for the prediction of germanium, the article on John Newlands links to his original papers with some added modern footnotes.

These discoveries, verifying his predictions and substantiating his law, took him to the top of the science.
Dmitri Mendeleev was a famous Russian chemist and inventor who formulated Periodic Law and created his own version of the Periodic Table of Elements. He used the table to correct properties of some discovered elements and to predict elements that were yet to be discovered.
