Biography of Friedrich Arnold
Friedrich Arnold was privy counsellor and professor emeritus of anatomy and physiology at Heidelberg. He studied medicine at the University of Heidelberg with his elder brother Johann Wilhelm Arnold (1801-1873). His anatomy-teachers were Friedrich Tiedemann (1781-1861) and Formann. He was conferred doctor of medicine on September 7, 1825.
In 1826 Arnold visited the institutions of natural sciences and medicine in Paris with his brother, and in the autumn that year was called to Heidelberg as professor at the anatomical institution of that town. In 1834 he was appointed extraordinary professor at the faculty of medicine in Heidelberg, and in 1835 accepted an invitation to become professor at and director of the institute of anatomy at the University of Zurich, where he stayed for five years.
All of Arnolds early works in anatomy and physiology concerned the microanatomy of the nervous system, but his long list of publications include a variety of themes. Of special importance is his textbook Lehrbuch der Physiologie der menschen, published with his brother. His illustrated works, of which the first was Icones nervorum capitis, are unique in German medical literature for their artistic merits.
In the spring of 1840 Arnold entered the chair of anatomy and physiology at the University of Freiburg im Breisgau, where he continued his research and began publishing his Handbuch der Anatomie des Menschen, ... At easter time 1845, after repeated invitations, he accepted the chair of anatomy and physiology at Tübingen, and in the autumn of 1852 assumed the same chair at the University of Heidelberg. Here, in 1873, he completed his career where it hand begun.
In volume one of his textbook of physiology is recorded work that he commenced as early as in 1832. This work is of particular importance because it is the basis for Rudolf Arndt's (1835-1900) theories on the build and development of the histological element of the animal body.
Arnold was a popular teacher, a man of vivid appearance and a deep concern for the welfare of his students.
