  Julius Lothar Meyer:   (Site not responding. Last check: 2007-10-21)
Julius Lothar Meyer (August 19, 1830 - April 11, 1895) was born in Varel, at that time belonging to the duchy of Oldenburg, now part of Germany.
In 1864, Meyer published an early version of the periodic table, containing 28 elements classified into 6 families by their valence—the first time that elements had been grouped and ordered according to their valence.
Meyer's contributions also included the concept that the carbon atoms in benzene were arranged in a ring, although he did not propose the alternation of single and double bonds that later became included in the structure by Kekulé.

Meyer, der ab 1859 Lehrveranstaltungen durchführte, hat wie Mendelejew den Lehrstoff mangels geeigneter Vorlagen selbst zusammengestellt.
Hier stellte Meyer die Elemente der heutigen Hauptgruppen sortiert nach Atomgewicht in Perioden zu 6 Gruppen nach Wertigkeit zusammen.
Meyers Zeitgenossen, Mendelejew eingeschlossen, stellten sich Atome als einheitliche Kugeln vor, während er schon 1864 einen inneren Aufbau als Ursache der Periodizität der chemischen Elemente annahm.

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.

Julius Lothar Meyer (1830 –; 1895) was active in many fields of chemistry.
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.
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.

 Julius Lothar Meyer and Dmitri Ivanovich Mendeleev   (Site not responding. Last check: 2007-10-21)
Julius Lothar Meyer (1830—1895) and Dmitri Ivanovich Mendeleev (1834—1907) worked with Robert Bunsen at Heidelberg only five years apart, but they arrived there with significantly different backgrounds.
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.

 Julius Lothar Meyer Biography / Biography of Julius Lothar Meyer World of Chemistry Biography
Julius Meyer, most often known as Lothar Meyer, was the son of a prominent physician and a physician's daughter.
Meyer's interest in the chemical teachings of Jöns Berzelius, the creator of the system of using initial letters for symbols of chemical elements, coupled with the his work with gases apparently prepared him to tackle the chaos in chemical terminology and nomenclature that existed in the mid-nineteenth century.
Meyer conducted a large volume of chemical work in other fields including molecular volumes, solubilities, diffusion, boiling point, chlorine and oxygen carriers, and mass action.

 PERIODIC LAW
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.

In 1864, Meyer published an early version of the periodic table, containing 28 elements classified into 6 families by their valence —the first time that elements had been grouped and ordered according totheir valence.
Working completely independently, a few months later, Meyer published a revised andexpanded version of his 1864 table, virtually identical to that prublished by Mendeleev, and a paper showing graphically theperiodicity of the elements as a function of atomic weight.
Meyer's contributions also included the concept that the carbon atoms in benzene were arranged in a ring, although he did not propose the alternation of single anddouble bonds that later became included in the structure by Kekulé.

 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.
The periodic table of the elements, first developed independently by Dmitri Ivanovich Mendeleyev of Russia and Lothar Meyer of Germany, can be explained crudely by the sequential filling of hydrogen-like eigenstates.

Russian chemist Dmitri Ivanovich Mendeleyev and German physicist Julius Lothar Meyer independently developed the periodic law of the chemical elements at about the same time in the late 19th century.
Mendeleyev is generally credited with the findings, because he established the periodic law in 1869, and Meyer established this chemical law in 1870.
Both discovered that arranging the elements in order of increasing atomic mass produced a table of chemical properties and reactivity patterns that were regularly repeated.
