Google Doodle praises the 190th birthday celebration of German chemist Julius Lothar Meyer on August 19, 2020.
Who was Julius Lothar Meyer?
Julius Lothar Meyer was born on 19 August 1830 in Varel, Germany (then part of the Duchy of Oldenburg) into a medical family. He was a German chemist, professor, and author also. He was one of the pioneers in building up the first periodic table of chemical elements. Both Mendeleev and Meyer worked with Robert Bunsen. He never used his initially given name and was referred to throughout his life just as Lothar Meyer.
In the wake of going to the Altes Gymnasium in Oldenburg, Julius Lothar Meyer studied medicine at the University of Zurich in 1851. After two years, he learned at the University of Würzburg, where he studied pathology, as a student of Rudolf Virchow. He finished his graduation as a Doctor of Medicine in 1854.
In 1858, Julius Lothar Meyer got a Ph.D. in chemistry from the University of Breslau with a thesis on the impacts of carbon monoxide on the blood. With this interest in the physiology of respiration, he had perceived that oxygen joins with the hemoglobin in the blood.
Gustav Kirchhoff’s mathematical teaching affected Julius Lothar Meyer a lot. He took up the study of mathematical physics at the University of Königsberg under Franz Ernst Neumann, and in 1859, in the wake of having gotten his habilitation (certification for university teaching), he became Privatdozent in physics and chemistry at the University of Breslau.
He acknowledged a post at the Eberswalde Forestry Academy at Neustadt-Eberswalde in 1866. Be that as it may, in 1888, he was delegated to a professorship at the Karlsruhe Polytechnic.
Julius Lothar Meyer’s resulting 1870 paper was historic in its own right, as its graphical showing of the connection between atomic volume and atomic weight gave solid proof to the periodic law depicting cyclical patterns among the elements.
In 1872, many may not realize that Julius Lothar Meyer was the first to recommend that the six carbon atoms in the benzene ring were interconnected by single bonds just, the fourth valence of every carbon atom being coordinated toward the interior of the ring. His claim was before proposed by August Kekulé.
During the Franco-German campaign, the Polytechnic was used as a hospital, and Julius Lothar Meyer played an active role under the care of the injured. In 1876, Meyer became Professor of Chemistry at the University of Tübingen, where he served until his death.
Julius Lothar Meyer is most popular as far as concerns him in the periodic classification of the elements. His book, Die modernen Theorien der Chemie (“Modern Chemical Theory”), which he started writing in Breslau in 1862 and which was published two years after the fact, contained an early form of the periodic table containing 28 elements, classified elements into six families by their valence—for the first time, elements had been gathered by their valence.
Julius Lothar Meyer planned a more comprehensive table in 1868, yet before he could publish, Dmitri Ivanovich Mendeleev released his paper that set all the known elements in a single table and established his place in science history.
In 1869, he published a paper that incorporated a revised version of his 1864 table that presently included virtually the entirety of the known elements, which was like the table published by Mendeleev. He had built up his more full periodic table independently, however, he recognized Mendeleev’s need.
In 1882, both Meyer and Mendeleev got the Davy Medal from the Royal Society in acknowledgment of their work on the Periodic Law.
Julius Lothar Meyer died at 65 years old on April 11, 1895, at Tübingen, Kingdom of Württemberg.
