German physiologist, comparative anatomist, ichthyologist, and herpetologist, known not only for his discoveries but also for his ability to synthesize knowledge. He was archiv für Naturgeschichte, 1889, Vol. 2 PDF son of a poor shoemaker, and was about to be apprenticed to a saddler when his talents attracted the attention of his teacher, and he prepared himself to become a Roman Catholic Priest. When he was 18 though, his love for natural science became dominant, and he turned to medicine, entering the University of Bonn in 1819.

Författare: F. Hilgendorf.

He became Privatdozent of physiology and comparative anatomy at Bonn in 1824, extraordinary professor of physiology in 1826, and ordinary professor in 1830. In 1833 he went to the Humboldt University of Berlin, where he filled the chair of anatomy and physiology until his death. In the century preceding Müller’s work, many contributions to physiological science had been made. Müller gave order to these facts, developed general principles and showed physiologists how recent discoveries in physics and chemistry could be applied to their work. The most important portion of the work was that dealing with nervous action and the mechanism of the senses. Here he stated the principle, previously recognized but not stated as clearly, that the kind of sensation following stimulation of a sensory nerve does not depend on the mode of stimulation but upon the nature of the sense organ. The book became the leading textbook in physiology for much of the nineteenth century.

It manifests Müller’s interests in vitalism, philosophy and scientific rigor. He discusses the difference between inorganic and organic matter. He considers in detail various physiological systems of a wide variety of animals, but attributes the indivisible whole of an organism to the presence of a soul. Muller as the „one of the greatest living physiologists, Muller of Berlin“. In the later part of his life he chiefly devoted himself to comparative anatomy. Fishes and marine invertebrata were his favorite subjects. He authored a comprehensive work on the anatomy of amphibians, which in his era including reptiles.

Also, he described several new species of snakes. Müller died in Berlin in 1858. In 1899, a bronze statue by Joseph Uphues was erected in his memory at Koblenz.
