Julius Lothar von Meyer was a German chemist. He was contemporary and competitor of Dmitri Mendeleev to draw up the first Periodic Table of chemical elements.
Meyer is best known for the share he had in the periodic classification of the elements. He noted that if they are arranged in the order of their atomic weights they fall into groups in which similar chemical and physical properties are repeated at periodic intervals; and in particular he showed that if the atomic weights are plotted as ordinates and the atomic volumes as abscissae, the curve obtained presents a series of maxima and minima, the most electro-positive elements appearing at the peaks of the curve in the order of their atomic weights.
This scientist was J. J. Thomson.
Unknown to Mendeleev, Lothar Meyer was also working on a periodic table. Although his work was published in 1864, and was done independently of Mendeleev, few historians regard him as an equal co-creator of the periodic table.
Meyer developed a table that was similar to modern periodic table. But his work was published later after Mendeleev.
The periodic law was revised by English scientist Henry Moseley. While investigating the X-Rays of elements in the laboratory of Rutherford, he discovered that each element was specifically associated with an atomic number. The arrangement of the elements in increasing atomic number led to the correct alignment of the elements.
Several chemists who contributed during the time were Lavoisier, Dobereiner, Newlands,Dumas, Gmelin, Chancourtois, Lothar Meyer, Odling, Mendeleev, Moseley, Seaborg, etc.
Julius Lothar Meyer devised a classification of elements into a table that accounted for the periodic variation in properties. his table included 56 elements.
Lothar Meyer's periodic table did not account for all known elements and did not correctly predict the properties of undiscovered elements. Additionally, it did not account for the concept of atomic number, which led to inconsistencies in the ordering of elements. Meyer's table also lacked a clear underlying periodic trend.

He helped create the periodic table but Mendeleev beat him to it.
This scientist was J. J. Thomson.

Dmitri Mendeleev and Julius Lothar Meyer independently published there versions of the Periodic Table between 1869 and 1870. Mendeleev's version would become the foundation of the table used today.
A variety of people are claimed to have helped create the periodic table including Kekule and John Newlands, but the credit to how the Periodic Table currently looks (some gaps filled in by other chemists) typically goes to Mendeleev.
He helped with the periodic table of elemnts.
