  Lothar Meyer
Lothar Meyer (in full, Julius Lothar von Meyer) (1830-1895) was a German chemist.
Meyer was born in Varel[?], at that time belonging to the duchy of Oldenburg, now part of Germany.
Meyer's contributions also included the concept that the carbon atoms in benzene were arranged in a ring, though he did not propose the alternation of single and double bonds that later became included in the structure by Kekulé.

Meyer was born in Varel, Lower Saxony, and studied at Zürich, Switzerland, and at several German universities.
In 1870 he published a graph of atomic volume (atomic weight divided by density) against atomic weight, which demonstrated the periodicity in the variation of the elements' properties.
Meyer never claimed priority for his findings and, unlike Mendeleyev, he made no predictions about the composition and properties of any elements still to be discovered.

Meyer and Mendeleev were among the young chemists attending the Karlsruhe Congress in 1860, and both were impressed with Stanislao Cannizzaro's presentation of Amadeo Avogadro's hypothesis.
Whereas Meyer continued to pursue a life of research and teaching, and spent the last twenty years of his life as a professor at Tübingen, Mendeleev's strong democratic leanings got him into trouble with political and academic authorities, although his scientific eminence and the usefulness of his advice protected him to a certain degree.

 PERIODIC LAW   (Site not responding. Last check: 2007-10-22)
The chemical law that the properties of all the elements are periodic functions of their atomic weights was developed independently by two chemists: in 1869 by Dmitry Mendeleyev, a Russian, and in 1870 by Julius Lothar Meyer, of Germany.
The key to the success of their efforts was the realization that previous attempts had failed because a number of elements were as yet undiscovered and that vacant places must be left for such elements in the classification.
The discovery of scandium proved to be one of a series of dramatic verifications of the predictions based on the periodic law, and validation of the law accelerated the development of inorganic chemistry.

Chemists Dmitrii I. Mendeleev, a Russian, and Lothar Meyer a German, were working independently in 1868 and 1869 on the arrangement of elements into seven columns, corresponding to various chemical and physical properties.
Unfortunately before Meyer's table appeared in 1870, Mendeleev's table became available to the scientific community via publication (1869) with his "periodic law" stating that the sequence of elements depends on their atomic weight.
The "modern" periodic table is very much like a later table proposed by Meyer, arranged, as was Mendeleev's, according to the size of the atomic weight, but with Group zero added by Ramsay.

 The Periodic Table
Meyer's 1864 textbook included a rather abbreviated version of a periodic table used to classify the elements.
In 1913, Henry Moseley (see a picture) published the results of his measurements of the wavelengths of the x-ray spectral lines of a number of elements which showed that the ordering of the wavelengths of the x-ray emissions of the elements coincided with the ordering of the elements by atomic number.
The question of why the periodic law exists was answered as scientists developed an understanding of the electronic structure of the elements beginning with Niels Bohr's studies of the organization of electrons into shells through G.N. Lewis' (see a picture) discoveries of bonding electron pairs.

 Meyer, Lothar --  Encyclopædia Britannica
In spite of the corrections made by the redetermination of atomic weights, some of the elements in the Mendeleyev and Lothar Meyer periodic tables of 1871 were still required by their properties to be put in positions somewhat out of the order of atomic weights.

Meyer had been strongly influenced by the ideas of Cannizzaro and first presented his ideas on the relation of the properties of elements and their atomic weights in 1864.
His table was very similar to that of Mendeleev, but it contained some improvements and was, perhaps, influential in causing some of the revisions made by Mendeleev in the second version of his table, published in 1870.
In general, Meyer was more impressed by the periodicity of the physical properties of the elements, while Mendeleev saw more clearly the chemical consequences of the periodic law.

 Discovery of Germanium
Thus the present case shows very clearly how treacherous it can be to build upon analogies; the quadrivalency of germanium has by now become an incontrovertible fact, and there can be no longer any doubt that the new element is no other than the eka-silicium prognosticated fifteen years ago by Mendeleev.
Lothar Meyer early declared germanium to be eka-silicium and added that according to his curve of the atomic volumes it should be low-melting and perhaps easy to evaporate.
At that time, germanium had not yet been produced in crystallized form; it is so much more remarkable that, as will be shown, Lothar Meyer's prediction has come true to a certain degree.

Meyer said the insurer is ``thinking about entering additional markets,'' and will expand in countries such as Russia, Ukraine, Bulgaria or Romania ``within the next three years.'' Ergo has no plans to make purchases at home.

Chemists Dmitrii I. Mendeleev (Russia), and Lothar Meyer (Germany) were working independently in 1868 and 1869 on similar table of elements grouped into seven columns according to chemical and physical properties.
In 1870 Meyer's table and periodic law was published, an accurate accounting of the then known facts about each element, which clearly indicated the existence of periodic chemical families, but focused on physical properties.
William Ramsay produced a more modern table that was similar to a later table by Meyer and arranged, as was Mendeleyev's, according to atomic weight, but with Group 0.
