MOHR, KARL FRIEDRICH (1806–1879), German pharmacist, son of a well-to-do druggist in Coblentz, was born on the 4th of November 1806. Being a delicate child he received much of his early education at home, in great part in his father’s laboratory. To this may be traced much of the skill he showed in devising instruments and methods of analysis. At the age of twenty-one he began to study chemistry under Leopold Gmelin, and, after five years spent in Heidelberg, Berlin and Bonn, returned with the degree of Ph.D. to join his father’s establishment. On the death of his father in 1840 he succeeded to the business, retiring from it for scientific leisure in 1857. Serious pecuniary losses led him at the age of fifty-seven to become a privatdozent in Bonn, where in 1867 he was appointed, by the direct influence of the emperor, extraordinary professor of pharmacy. He died at Bonn on the 28th of September 1879. Mohr was the leading scientific pharmacist of his time in Germany, and he was the author of many improvements in analyt

analytical chemistry, physical chemistry, agricultural chemistry, geology.

Mohr’s father, Karl, was an apothecary and city councillor. After completing secondary school, Mohr attended the University of Bonn, where he studied botany, chemistry, and mineralogy. After gaining practical experience with his father, he attended the chemistry lectures of Leopold Gmelin at Heidelberg and those of Heinrich Rose in analytical chemistry at Berlin. He then obtained his degree in pharmacy and took over his father’s business. Besides attending to the business, he was interested in various areas of science. In 1833 he married Jacobine Derichs; they had three sons and two daughters.

In 1837 Mohr published an essay, “Ansichten über die Natur der Wärme,”in which he wrote:“Apart from the known chemical elements, there exists in nature only one agent, and that is force; it can show itself in appropriate relationships as motion, chemical affinity, cohesion, electricity, light,

from The Popular Science Monthly (1880)

[p.402]On September 28, 1879, the earthly career of a man closed at Bonn, Germany, whose numerous original researches and contributions to pharmacy, chemistry, chemical analysis, geology, and other branches of the physical and applied sciences, have placed him in the foremost ranks of scientific investigators. Karl Friedrich Mohr was born November 4, 1806, at Coblentz, on the Rhine, where his father was an apothecary. After having completed the full course of the gymnasium of his native city, he entered, in 1823, his father’s establishment as an apprentice. In 1828 he went to the University of Heidelberg, where he applied himself to the study of philosophy, the natural sciences, and pharmacy, and where, by the influence and guidance of Leopold Gmelin, his interest was particularly drawn to chemistry; he subsequently studied at the Universities of Berlin and Bonn, and in 1831 graduated as doctor of philosophy. After having passed the sta
