Virchow is credited with multiple significant discoveries. Although he and Theodor Schwann are not mentioned together, his most widely known is indeed his cell theory. He is cited as the first to recognize leukemia. However, he is perhaps best known for his theory Omnis cellula e cellula ("every cell originates from another existing cell like it.") which he published in 1858. (The epigram was actually coined by François-Vincent Raspail but popularized by Virchow). It is a rejection of the concept of spontaneous generation, which held that organisms could arise from non-living matter. It was believed, for example, that maggots could spontaneously appear in decaying meat; Francesco Redi carried out experiments which disproved this. Redi's work gave rise to the maxim Omne vivum ex ovo ("every living thing comes from a living thing" [literally, "from an egg"]), Virchow (and his predecessors) extended this to state that the only source for a living cell was another living cell.
Another significant credit relates to the discovery, made approximately simultaneously by Virchow and Charles Emile Troisier, that an enlarged left supra-clavicular node is one of the earliest signs of gastrointestinal malignancy, commonly of the stomach, or less commonly, lung cancer. This has become known as Virchow's node and simultaneously Troisier's sign.
Virchow is also famous for elucidating the mechanism of pulmonary thromboembolism, 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 described the factors contributing to venous thrombosis, Virchow's triad.
Furthermore, Virchow founded the medical disciplines of cellular pathology, comparative pathology (comparison of diseases common to humans and animals). 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 1885 he launched a study of craniometry, which gave surprising results according to contemporary scientific racist theories on the "Aryan race", leading him to denounce the "Nordic mysticism" in the 1885 Anthropology Congress in Karlsruhe. Josef Kollmann , a collaborator of Virchow, stated in the same congress that the people of Europe, be them German, Italian, English or French, belonged to a "mixture of various races," furthermore declaring that the "results of craniology" led to "struggle against any theory concerning the superiority of this or that European race" on others .
In 1892 he was awarded the Copley Medal.
He was a very prolific writer. Some of his works are:
He also developed a standard method of autopsy procedure, named for him, that is still one of the two main techniques used today. More than a laboratory physician, Virchow was an impassioned advocate for social and political reform, stating that physicians should act as "attorneys for the poor." His views are evident in his "Report on the Typhus Outbreak of Upper Silesia (1848), "writing that the outbreak could not be solved by treating individual patients with drugs or with minor changes in food, housing, or clothing laws, but only through radical action to promote the advancement of an entire population. He is widely regarded as a pioneer of social medicine. and anthropology.

It is said (though not confirmed) that Otto von Bismarck challenged Rudolf Virchow to a duel. Virchow, as the challenged party had the choice of weapons; he chose two sausages, one of which had been inoculated with cholera. Bismarck is said to have called off the duel at once.
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.
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.
The Society for Medical Anthropology gives an annual award in Virchow's name, Rudolph Virchow Award.
