Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
he was the man behind the discovery of periodic table according to the atomic numbers
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.

The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today.
If you are talking about Dmitri Mendeleev, he was the first to come up with the first periodic table and the periodic law.
