Zagadka tablitsy Mendeleeva - Druzhinina P.

According to popular legend, D.I. Mendeleev discovered his famous Periodic Law in his sleep. Historians of science have long refuted this apocryph, but they never doubted the date of the publication of the law - March 1, 1869. On this day, as Mendeleev himself wrote, he sent the first-printed Table to "many chemists." But wasn't the scientist wrong? Didn't wishful thinking? The well-known historian Piotr Druzhinin for the first time criticized the generally accepted data on the publication of the discovery. Relying on unknown archival documents and unaccounted-for sources, the author was able not only to re-build the chronology of the appearance in print of the original version of the Mendeleev Table, but also to establish precisely the date of the first publication of the Periodic Law - one of the fundamental laws of natural science.
