Rudolf Ludwig Karl Virchow (born October 13, 1821, in Schivelbein, Pomerania; died September 5, 1902, in Berlin) was a German doctor, anthropologist, public health activist pathologist, prehistorian, biologist and politician.

From a farming family of relatively modest means, Virchow studied medicine in Berlin at the military academy of Prussia on a scholarship. When he graduated in 1842 he went to serve as Robert Froriep's assistant at the Berlin Charité rather than the expect military service. He became professor in 1847. Due to political reasons, he moved to Würzburg two years later, where he worked on anatomy. In 1856, he returned to Berlin as a professor of anatomic pathology (a chair created just for him) at Berlin University and the Berlin Charité where he had previously worked as Froriep's assistant. One of major contributions to German medical education was to encourage the use of microscopes by medical students and was known for constantly urging his students to 'think microscopically'.

Virchow is credited with multiple significant discoveries. He is cited as the first to recognize leukemia. However, he is perhaps best known for his law Omnis cellula e cellula ("every cell originates from another cell") which he published in 1855. (The epigram was actually coined by François-Vincent Raspail but popularized by Virchow.) This relates to his findings that not the whole organism, but only certain cells or groups of cells can become sick. Virchow is also famous for elucidating the mechanism of pulmonary thromboembolism, thus coining the term embolism. He noted that blood clots in the pulmonary artery originate first from venous thrombi, stating: "The detachment of larger or smaller fragments from the end of the softening thrombus which are carried along by the current of blood and driven into remote vessels. This gives rise to the very frequent process on which I have bestowed the name of Embolia." Related to this research Virchow has been attributed a triad describing the factors contributing to venous thrombosis, Virchow's triad. Virchow founded the medical disciplines of cellular pathology, comparative pathology (comparison of diseases common to humans and animals) and anthropology. His very innovative work may be viewed as sitting between that of Morgagni whose work Virchow studied and that of Paul Ehrlich, who studied at the Charité while Virchow was developing microscopic pathology there.

In 1869 he founded the Society for anthropology, ethnology and prehistory (Gesellschaft für Anthropologie, Ethnologie und Urgeschichte) which was very influential in coordinating and intensifying German archaeological research.

In 1892 he was awarded the Copley Medal.

He was a very prolific writer. Some of his works are:

Mittelheilungen über die Typhus-Epidemie, (1848)
Die Cellularpathologie, (1858), English translation, (1860)
Handbuch der speciellen Pathologie und Therapie, (1854-62)
Vorlesungen über Pathologie, (1862-72)
Die krankhaften Geschwülste, (1863-67)
Gegen den Antisemitismus, (1880)
He also developed a standard method of autopsy procedure, named for him, that is still one of the two main techniques used today.


Virchow also worked as a politician (member of the Berlin City Council, the Prussian parliament since 1861, German Reichstag 1880-1893) to improve the health care conditions for the Berlin citizens, namely working towards modern water and sewer systems. Virchow is also credited with the founding of "social medicine", frequently focusing on the fact that disease is never purely biological, but often, socially derived. As a co-founder and member of the liberal party (Deutschen Fortschrittspartei) he was an important political antagonist of Bismarck.

One area where he co-operated with Bismarck was in the Kulturkampf, the anti-clerical campaign against the Catholic Church claiming that the anti-clerical laws bore "the character of a great struggle in the interest of humanity". It was during the discussion of Falk’s May Laws (Maigesetze) that Virchow first used the term

The general ideological enthusiasm among the liberals for the Kulturkampf was in contrast to Bismarck's pragmatic attitude towards the measures and growing disquiet from the Conservatives.

Virchow was respected in masonic circles, and according to one source may have been a freemason, though no official record of this has been found.

Virchow, Rudolf (1821-1902), German pathologist, archaeologist, and anthropologist, the founder of cellular pathology. Virchow was born in Schivelbein, Pomerania (now Świdwin, Poland), and educated at the University of Berlin. In 1843 he became prosector at the Charité Hospital in Berlin, and in 1847 a university lecturer. In 1849 he was invited to the medical school of Würzburg as professor of pathological anatomy, having been dismissed from his Berlin posts because of revolutionary activities. In 1856 he returned to Berlin as professor and director of the university's pathological institute.

Virchow was the first to demonstrate that the cell theory applies to diseased tissue as well as to healthy tissue—that is, that diseased cells derive from the healthy cells of normal tissue. He did not, however, accept Louis Pasteur's germ theory of disease. He is best known for his text Cellular Pathology as Based on Histology (1850; trans. 1860). He engaged also in extensive research in the fields of archaeology and anthropology, producing numerous writings, among them Crania Ethnica Americana (1892). Other publications include discussions of topical political and social questions. Virchow was influential in German politics and from 1880 to 1893 served as a Liberal in the German Reichstag, where he opposed the policies of the German chancellor Prince Otto von Bismarck. He was instrumental in the establishment of the Pathological Institute and Museum in Berlin.
