Two years later he got the position of professor of chemistry and director of the corresponding laboratory at the Polytechnic Institute of Karlsruhe. The same year he married, in 1866, he changed his place of work and moved to the School of Forestry. Likewise, he was offered the address of the chemistry laboratory at the Institute of Physiology. That is why, after presenting his thesis, he began teaching at Breslau as a professor of medicine. One of Meyer's great passions was teaching. Meanwhile, he obtained his PhD from the University of Breslau in 1858, presenting a thesis on the carbon monoxide present in the blood. He is so interested in the subject that he stays at the university working after graduating. There is another famous scientist of his time: Professor Robert Bunsen. Two years later he moved to Würzburg, interested in the work of the considered father of modern pathology, Rudolf Virchow, who taught there.Īfter obtaining the title the following year, Meyer gives a change to his career and decides to go to Heidelberg to study physiological chemistry. As it could not be less, it enters in the faculty of Medicine of the University of Zurich. The same year he graduated from the Gymnasium, Meyer began his university studies. As an anecdote, it can be noted that after this experience he had a great fondness for gardening, a practice he never abandoned. Whatever it was, Meyer's health improved a lot after a year taking care of the gardens and he was able to resume his training by entering the Gymnasium. He pretended that the natural environment and to stop striving intellectually would alleviate the sufferings of the young man. When Meyer was 14 years old, his father decided that he should leave school and sent him to work as a gardening assistant in a palace of the nobility. Meyer had many health problems and suffered from severe migraines. However, an event was on the verge of not allowing him to continue studying. ![]() ![]() First he studies in a private school newly created in his city, and those teachings are complemented with the assistance to other private centers to learn Latin and Greek. First studiesįrom his early years, Meyer receives a quality education. That is why, both he and another of his brothers, focus their studies towards that discipline. Given his family background he seemed destined to become a doctor: his father was, like his maternal grandfather. He was the fourth of seven brothers and was educated in Lutheranism. Julius Lothar Meyer was born on Augin Varel, Oldenburg, a town that is now part of Germany. 2 The 2 most important contributions to science by Julius Lothar Meyer.He noticed that elemental properties repeated every seventh (or multiple of seven) element, as musical notes repeat every eighth note. John Alexander Reina Newlands was an English chemist who worked on the development of the periodic table. ![]() Despite the fact that Newlands’s table had no logical place for the d-block elements, he was honored for his idea by the Royal Society of London in 1887. At one scientific meeting, Newlands was asked why he didn’t arrange the elements in alphabetical order instead of by atomic mass, since that would make just as much sense! Actually, Newlands was on the right track-with only a few exceptions, atomic mass does increase with atomic number, and similar properties occur every time a set of ns 2 np 6 subshells is filled. Unfortunately, Newlands’s “law of octaves” did not seem to work for elements heavier than calcium, and his idea was publicly ridiculed. There were seven elements because the noble gases were not known at the time. ![]() He described octaves as a group of seven elements which correspond to the horizontal rows in the main groups of today's periodic table. Newlands therefore suggested that the elements could be classified into octaves.
