Lothar Meyer (1830–1895), a German chemist, prepared a periodic table that resembled closely Mendeleyev’s periodic table. He did not publish his periodic table until after Mendeleyev’s paper on the periodic table was published in 1869. It is believed his work was influential in causing some of the revisions Mendeleyev made in the second version of his periodic table, published in 1870. Specifically, Meyer focused on the periodicity of the physical properties of the elements, while Mendeleyev’s focus was the chemical consequences of the periodic law.
