Rudolf Ludwig Carl Virchow (English /, /; German: [ˈvɪɐ̯çoː]; 13 October 1821 – 5 September 1902) was a German doctor, anthropologist, pathologist, prehistorian, biologist, writer, editor, and politician, known for his advancement of public health. He is known as "the father of modern pathology" because his work helped to discredit humourism, bringing more science to medicine. He is also known as the founder of social medicine and veterinary pathology, and to his colleagues, the "Pope of medicine".
Born and lived in Schievelbein (Świdwin) as an only child of a working-class family, he proved to be a brilliant student. Dissuaded by his weak voice, he abandoned his initial interest in theology and turned to medicine. With special military scholarship, he earned his medical degree from Friedrich-Wilhelms Institute (Humboldt University of Berlin) under the tutelage of Johannes Peter Müller. He worked at the Charité hospital under Robert Froriep, whom he eventually succeeded as the prosector.
Although he failed to contain the 1847–1848 typhus epidemic in Upper Silesia, his report laid the foundation for public health in Germany, as well as his political and social activities. From it, he coined a well known aphorism: "Medicine is a social science, and politics is nothing else but medicine on a large scale". He participated in the Revolution of 1848, which led to his expulsion from Charité the next year. He published a newspaper Die medicinische Reform (Medical Reform) during this period to disseminate his social and political ideas. He took the first Chair of Pathological Anatomy at the University of Würzburg in 1849. After five years, Charité invited him back to direct its newly built Institute for Pathology, and simultaneously becoming the first Chair of Pathological Anatomy and Physiology at Berlin University. The campus of Charité is now named Campus Virchow Klinikum. He cofounded the political party Deutsche Fortschrittspartei, by which he was elected to the Prussian House of Representatives, and won a seat in the Reichstag. His opposition to Otto von Bismarck's financial policy resulted in an anecdotal "Sausage Duel" between the two. But he ardently supported Bismarck in his anti-Catholic campaigns, the social revolution he himself named as Kulturkampf ("culture struggle").
A prolific writer, his scientific writings alone crossed 2,000 in number. Among his books, Cellular Pathology published in 1858 is regarded as the root of modern pathology. This work also popularised the third dictum in cell theory: Omnis cellula e cellula ("All cells come from cells"); although his idea originated in 1855. He founded journals such as Archiv für pathologische Anatomie und Physiologie und für klinische Medizin (now Virchows Archiv), and Zeitschrift für Ethnologie (Journal of Ethnology). The latter is published by German Anthropological Association and the Berlin Society for Anthropology, Ethnology and Prehistory, the societies of which he also founded.
Virchow was the first to precisely describe and give names of diseases such as leukemia, chordoma, ochronosis, embolism, and thrombosis. He coined scientific terms, chromatin, agenesis, parenchyma, osteoid, amyloid degeneration, and spina bifida. His description of the transmission cycle of a roundworm Trichinella spiralis established the importance of meat inspection, which was started in Berlin. He developed the first systematic method of autopsy involving surgery of all body parts and microscopic examination. A number of medical terms are named after him, including Virchow's node, Virchow–Robin spaces, Virchow–Seckel syndrome, and Virchow's triad. He was the first to use hair analysis in criminal investigation, and recognised its limitations. His laborious analyses of the hair, skin, and eye colour of school children made him criticise the Aryan race concept as a myth.
He was an ardent anti-evolutionist. He referred to Charles Darwin as "ignoramus" and his own student Ernst Haeckel, the leading advocate of Darwinism in Germany, as a "fool". He discredited the original specimen of Neanderthal as nothing but that of a deformed human, and not an ancestral species. He was an agnostic.
In 1861, he was elected a foreign member of the Royal Swedish Academy of Sciences. In 1892, he was awarded the Copley Medal of the British Royal Society. He was elected to the Prussian Academy of Sciences in 1873, and entitled an ennoblement "von Virchow", but which he declined.

Life and scientific career
Virchow was born in Schievelbein in eastern Pomerania, Prussia (now Świdwin in Poland). He was the only child of Carl Christian Siegfried Virchow (1785–1865) and Johanna Maria née Hesse (1785–1857). His father was a farmer and the city treasurer. Academically brilliant, he always topped in his classes and was fluent in German, Latin, Greek, Hebrew, English, Arabic, French, Italian, and Dutch. He studied theology in gymnasium in Koslinka in 1835, from where he graduated in 1839 upon a thesis titled A Life Full of Work and Toil is not a Burden but a Benediction. However, he chose to take up medicine mainly because he considered his voice too weak for preaching.
In 1839, he received a military fellowship (a scholarship for gifted children from poor family to become army surgeon), for studying medicine at Friedrich-Wilhelms Institute in Berlin (now Humboldt University of Berlin). He was most influenced by Johannes Peter Müller. He defended his thesis titled de rheumate praesertim corneae (corneal manifestations of rheumatic disease) for medical degree on 21 October 1843, with Müller as his doctoral advisor. Immediately on graduation he became subordinate physician to Müller. But shortly after, he joined the Charité Hospital in Berlin for internship. In 1844, he was appointed as medical assistant to the prosector (pathologist) Robert Froriep, from whom he learned microscopy for his interest in pathology. Froriep was also the editor of an abstract journal that specialised in foreign work, allowing Virchow to be exposed to the more forward-looking scientific ideas of France and England.
Virchow published his first scientific paper in 1845 in which he wrote the earliest known pathological descriptions of leukemia. He qualified the medical licensure examination in 1846, and immediately succeeded Froriep as hospital prosector at the Charité. In 1847, he was appointed to his first academic position with the rank of privatdozent. Because his writings were not receiving favourable attention by German editors, with colleague Benno Reinhardt he founded Archiv für pathologische Anatomie und Physiologie und für klinische Medizin (now known as Virchows Archiv) in 1847. He edited alone from Reinhardt's death in 1852 until his own. This journal began publishing high-level contributions based on the criterion that no papers would be published which contained outdated, untested, dogmatic or speculative ideas. Unlike his German peers, Virchow used to have great faith that clinical observation, animal experimentation (to determine causes of diseases and the effects of drugs) and pathological anatomy, particularly at the microscopic level, were the basic principles of investigation in medical sciences. He went further and stated the cell was the basic unit of the body that had to be studied to understand disease. Although the term 'cell' had been coined in the 1665 by an English scientist Robert Hooke, the building blocks of life were still considered to be the 21 tissues of Bichat, a concept described by the French physician Marie Bichat.
The Prussian government deployed Virchow to study the typhus epidemic in Upper Silesia in during 1847–1848. It was from this medical campaign that he developed his ideas on social medicine and politics after seeing the victims and their poverty. Even though he was not particularly successful in combating the epidemic, his 190-paged Report on the Typhus Epidemic in Upper Silesia in 1848 became a turning point in politics and public health in Germany. He returned to Berlin on 10 March 1848, and only eight days later, a revolution broke out against the government in which he played an active part. To fight political injustice he helped finding Die medicinische Reform (Medical Reform), a weekly newspaper for promoting social medicine, in July of that year. The newspaper ran under the banners "medicine is a social science" and "the physician is the natural attorney of the poor". Political pressures forced him terminate the publication in June 1849 and became expelled from his official position. In November, he was given academic appointment and left Berlin for University of Würzburg to hold Germany's first chair of pathological anatomy. During his six-year period there, he concentrated on his scientific work, including detailed studies on venous thrombosis and cellular theory. His first major work there was a six-volume Handbuch der speciellen Pathologie und Therapie (Handbook on Special Pathology and Therapeutics) published in 1854. In 1856, he returned to Berlin to become the newly created Chair for Pathological Anatomy and Physiology at the Friedrich-Wilhelms-University, as well as Director of the newly built Institute for Pathology on the premises of the Charité. He held the latter post for the next 20 years.
Virchow is credited with several very important discoveries. His most widely known scientific contribution is his cell theory, which built on the work of Theodor Schwann. He was one of the first to accept the work of Robert Remak, who showed the origins of cells was the division of pre-existing cells. He did not initially accept the evidence for cell division, believing it only occurs in certain types of cells. When it dawned on him that Remak might be right, in 1855, he published Remak's work as his own, which caused a falling out between the two. This work, Virchow encapsulated in the epigram Omnis cellula e cellula, id est, All cells (come) from cells, which he published in 1855. (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 nonliving matter. For example, maggots were believed to spontaneously appear in decaying meat; Francesco Redi carried out experiments which disproved this notion and coined 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.
In 1845, Virchow and John Bennett independently observed abnormal increase in white blood cells in patients. Virchow correctly identified the condition as blood disease, and named it leukämie in 1847 (later anglicised to leukemia). In 1857, he was the first to describe a type of tumour called chordoma that originated from clivus (part of the skull).
Theory on cancer origin
Virchow was the first to correctly link the origin of cancers from otherwise normal cells. (His teacher Müller had proposed that cancers originated from cells, but from special cells, which he called blastema.) In 1855, he suggested that cancers arise from the activation of dormant cells (perhaps similar to cells now known as stem cells) present in mature tissue. Virchow believed that cancer is caused by severe irritation in the tissues, and his theory came to be known as chronic irritation theory. He thought, rather wrongly, that the irritation spread in the form of liquid so that cancer rapidly increases. His theory was largely ignored, as he was proved wrong that it was not by liquid, but by metastasis of the already cancerous cells that cancers spread. (First described by Karl Thiersch in the 1860s.) But he made a crucial observation that certain cancers (carcinoma in modern sense) were inherently associated with white blood cells (which are now called macrophages) that produced irritation (inflammation). It was only towards the end of the 20th century that Virchow's theory was taken seriously. It was realised that specific cancers (including those of mesothelioma, lung, prostate, bladder, pancreatic, cervical, esophageal, melanoma, and head and neck) are indeed strongly associated with long-term inflammation. In addition it became clear that long-term use of anti-inflammatory drugs, such as aspirin, reduced cancer risk. Experiment also shows that drugs that block inflammation simultaneously inhibit tumour formation and development.
The Kaiser's case
Virchow was one of the leading physicians to Kaiser Frederick III, who suffered from cancer of larynx. While other physicians such as Ernst von Bergmann suggested surgical removal of the entire larynx, Virchow opposed because no successful operation of such kind had ever been done. The British surgeon, Morell Mackenzie, performed a biopsy in 1887 and sent it to Virchow, who identified them as "pachydermia verrucosa laryngis". Virchow affirmed that the tissues were not cancerous, even after several biopsy tests. The Kaiser died on 15 June 1888. The next day a post-mortem examination was performed by Virchow and his assistant. They found that the larynx was extensively damaged due to ulcer, and microscopic examination confirmed epidermal carcinoma. Die Krankheit Kaiser Friedrich des Dritten (The Medical Report of Kaiser Frederick III) was published on 11 July under the lead authorship of Bergmann. But Virchow and Mackenzie were omitted, and they were particularly criticised for all their works. The arguments between them turned into a century-long controversy, resulting in Virchow being accused of misdiagosis and malpractice. But reassessment of the diagnostic history revealed that Virchow was right in his findings and decisions. It is now believed that the Kaiser had hybrid verrucous carcinoma, a very rare form of verrucous carcinoma, and that Virchow had no way of correctly identifying it. (The cancer type was correctly identified only in 1948 by Lauren Ackerman.)
Another significant credit relates to the discovery, made approximately simultaneously by Virchow and Charles Emile Troisier, that an enlarged left supraclavicular 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 known for elucidating the mechanism of pulmonary thromboembolism (a condition of blood clotting in the blood vessels), coining the terms embolism and thrombosis. He noted that blood clots in the pulmonary artery originate first from venous thrombi, stating in 1859: "[T]he 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." Having made these initial discoveries based on autopsies, he proceeded to put forward a scientific hypothesis; that pulmonary thrombi are transported from the veins of the leg and that the blood has the ability to carry such an object. He then proceeded to prove this hypothesis through well-designed experiments, repeated numerous times to consolidate evidence, and with meticulously detailed methodology. This work rebuked a claim made by the eminent French pathologist Jean Cruveilhier that phlebitis led to clot development and therefore coagulation was the main consequence of venous inflammation. This was a view held by many before Virchow's work. Related to this research, Virchow described the factors contributing to venous thrombosis, Virchow's triad.
Furthermore, Virchow founded the medical fields of cellular pathology and comparative pathology (comparison of diseases common to humans and animals). His most important work in the field was Cellular Pathology (Die Cellularpathologie in ihrer Begründung auf physiologische und pathologische Gewebelehre) published in 1858, as a collection of his lectures. This is regarded as the basis of modern medical science, and the "greatest advance which scientific medicine had made since its beginning." His very innovative work may be viewed as 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. One of Virchow's major contributions to German medical education was to encourage the use of microscopes by medical students, and he was known for constantly urging his students to "think microscopically". He was the first to establish to link between infectious diseases between humans and animals, for which he coined the term "zoonoses". He also introduced scientific terms such as "chromatin", "agenesis", "parenchyma", "osteoid", "amyloid degeneration", and "spina bifida". His concept on pathology directly opposed humourism, an ancient medical dogma that diseases were due to imbalanced body fluids, hypothetically called humours, that still pervaded.
Virchow worked out the life cycle of a roundworm Trichinella spiralis. Virchow noticed a mass of circular white flecks in the muscle of dog and human cadaver, similar to those described by Richard Owen in 1835. He confirmed through microscopic observation that the white particles were indeed the larvae of roundworms, being curled up in the muscle tissue. Rudolph Leukart found that these tiny worms could develop into adult roundworms in the intestine of a dog. He correctly asserted that these worms could also cause human helminthiasis. Virchow further demonstrated that if the infected meat is first heated to 137 °F for 10 minutes, the worms could not infect dogs or humans. He established that human infection occurs through contaminated pork. This directly led to the importance of meat inspection, which was first adopted in Berlin.
Virchow was the first to develop a systematic method of autopsy, based on his knowledge of cellular pathology. The modern autopsy still constitute his techniques. His first most significant autopsy was on a 50-year-old woman in 1845. He found from the body an unusual amount of white blood cells, and gave a detailed description in 1847 and named the condition as leukämie. One on his autopsies in 1857 was the first description of vertebral disc rupture. His autopsy on a baby in 1856 was the first description of congenital pulmonary lymphangiectasia (the name given by K. M. Laurence a century later), a rare and fatal disease of lung. From his experience of post-mortem examinations of a number of cadaver, he published his method in a small book in 1876. His book was the first to describe the techniques of autopsy specifically to examine abnormalities in organs, and retain important tissues for further examination and demonstration. Unlike any other procedure before, he practiced complete surgery of all body parts with body organs dissected one by one. This has become the standard method.
Virchow discovered the clinical syndrome which he called ochronosis, a metabolic disorder in which a patient accumulates homogentisic acid in connective tissues and is indicated by discolouration under microscope. He found the unusual symptom from an autopsy of the corpse of a 67-year-old man on 8 May 1884. This was the first time the abnormal disease causing cartilage and connective tissue was observed and analysed. His description and coining of the name appeared in the October 1866 issue of Vichows Archiv.
Virchow was the first to analyse hair in criminal investigation, and made the first forensic report on it in 1861. He was called as an expert witness in a murder case, and he used hair samples collected from the victim. He became the first to recognise the limitation of hair as a conclusive evidence. He found that hairs can be different in an individual, and individual hair has characteristic features, and that hairs from different individuals can be strikingly similar. He concluded that evidence based on hair analysis is inconclusive. His testimony runs:
[T]he hairs found on the defendant do not possess any so pronounced peculiarities or individualities that no one with certainty has the right to assert that they must have originated from the head of the victim.
Anthropology and prehistory biology
Virchow developed an interest in anthropology in 1865, when he discovered pile dwellings in northern Germany. In 1869, he co-founded the German Anthropological Association. In 1870 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. He edited its journal Zeitschrift für Ethnologie (Journal of Ethnology), which he founded in 1866, until his death, and was several times (at least fifteen times) its president. In 1870, he led a major excavation of the hill forts in Pomerania. He also excavated wall mounds in Wöllstein in 1875 with Robert Koch, whose paper he edited on the subject. For his contributions in German archaeology, the Rudolf Virchow lecture is held annually in his honour. He made field trips to Asia Minor, the Caucasus, Egypt, Nubia, and other places, sometimes in the company of Heinrich Schliemann. His 1879 journey to the site of Troy is described in Beiträge zur Landeskunde in Troas ("Contributions to the knowledge of the landscape in Troy", 1879) and Alttrojanische Gräber und Schädel ("Old Trojan graves and skulls", 1882).
Virchow was an opponent of Darwin's theory of evolution, and particularly skeptic of the emergent thesis of human evolution. On 22 September 1877, he delivered a public address entitled "The Freedom of Science in the Modern State" before the Congress of German Naturalist and Physicians in Munich. There he spoke against the teaching of the theory of evolution in schools, arguing that it was yet an unproven hypothesis that lacked empirical foundations and that, therefore, it could affect scientific studies. Ernst Haeckel, who had been Virchow's student, later reported that his former professor said that "it is quite certain that man did not descend from the apes...not caring in the least that now almost all experts of good judgment hold the opposite conviction."
Virchow became one of the leading opponents on the debate over the authenticity of Neanderthal, discovered in 1856, as distinct species and ancestral to modern humans. He himself examined the original fossil in 1872, and presented his observations before the Berliner Gesellschaft für Anthropologie, Ethnologie und Urgeschichte. He stated that the Neanderthal had not been a primitive form of human, but an abnormal human being, who, judging by the shape of his skull, had been injured and deformed, and considering the unusual shape of his bones, had been arthritic, rickety and feeble. With such an authority, the fossil was rejected as new species. With this reasoning, Virchow "judged Darwin an ignoramus and Haeckel a fool and was loud and frequent in the publication of these judgments."
On 22 September 1877, at the Fiftieth Conference of the German Association of Naturalists and Physician held in Munich, Haeckel pleaded for introducing evolution in the public school curricula, and tried to dissuade Darwinism from social Darwinism. His campaign was because of Herman Müller, a school teacher who was banned because of his teaching a year earlier on the inanimate origin of life from carbon. This resulted in prolonged public debate with Virchow. A few days later Virchow responded that Darwinism was only a hypothesis, and morally dangerous to students. This severe criticism of Darwinism was immediately taken up by the London Times, from which further debates erupted among English scholars. Haeckel wrote his arguments in the October issue of Nature titled "The Present Position of Evolution Theory", to which Virchow responded in the next issue with an article "The Liberty of Science in the Modern State". The debate made Haeckel write a full book Freedom in Science and Teaching in 1879. That year the issue was discussed in the Prussian House of Representatives and the verdict was in favour of Virchow. In 1882 the Prussian education policy officially excluded natural history in schools.
Years later, the noted German physician Carl Ludwig Schleich, would recall a conversation he held with Vichow, who was a close friend of him: "...On to the subject of Darwinism. "I don't believe in all this," Virchow told me. "if I lie on my sofa and blow the possibilities away from me, as another man may blow the smoke of his cigar, I can, of course, sympathize with such dreams. But they don't stand the test of knowledge. Haeckel is a fool. That will be apparent one day. As far as that goes, if anything like transmutation did occur it could only happen in the course of pathological degeneration!".
Virchow's ultimate opinion about evolution was reported a year before he died; in his own words:
The intermediate form is unimaginable save in a dream... We cannot teach or consent that it is an achievement that man descended from the ape or other animal.
Virchow believed that Haeckel's monist propagation of social darwinism was in its nature politically dangerous and anti-democratic, and he also criticized it because he saw it as related to the emergent socialist movement in Germany, ideas about cultural superiority, and militarism. In 1885, he launched a study of craniometry, which gave surprising results contradictory 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 they German, Italian, English or French, belonged to a "mixture of various races", furthermore declaring the "results of craniology" led to "struggle against any theory concerning the superiority of this or that European race" on others. He analysed the hair, skin, and eye colour of 6,758,827 school children to identify Jews and Aryans. His findings published in 1886, that there could not neither be Jewish nor German race, were regarded as a blow to anti-Semitism, and the existence of Aryan race.
Anti-germ theory of diseases
Virchow did not believe in the germ theory of diseases, as advocated by Louis Pasteur and Robert Koch. He proposed that diseases came from abnormal activities inside the cells, not from outside pathogens. He believed that epidemics were social in origin, and the way to combat epidemics was political, not medical. He regarded germ theory as hindrance to prevention and cure. He considered social factors such as poverty as major cause of diseases. He even attacked Koch's and Ignatz Semmelweis' policy of handwashing as an antiseptic practice. He postulated that germs were only using infected organs as habitats, but they were not the cause, and stated, "If I could live my life over again, I would devote it to proving that germs seek their natural habitat: diseased tissue, rather than being the cause of diseased tissue".
More than a laboratory physician, Virchow was an impassioned advocate for social and political reform. His ideology involved social inequality as the cause of diseases that requires political actions, stating:
Medicine is a social science, and politics is nothing else but medicine on a large scale. Medicine, as a social science, as the science of human beings, has the obligation to point out problems and to attempt their theoretical solution: the politician, the practical anthropologist, must find the means for their actual solution... Science for its own sake usually means nothing more than science for the sake of the people who happen to be pursuing it. Knowledge which is unable to support action is not genuine – and how unsure is activity without understanding... If medicine is to fulfill her great task, then she must enter the political and social life... The physicians are the natural attorneys of the poor, and the social problems should largely be solved by them.
Virchow actively worked for social change to fight poverty and diseases. His methods involves pathological observations and statistical analyses. He called this new field of social medicine as a "social science". His most important influences could be noted in Latin America, where his disciples introduced his social medicine. For example, his students Max Westenhöfer became Director of Pathology at the medical school of the University of Chile, becoming the most influential advocate. One of Westenhöfer's students, Salvador Allende, through social and political activities based on Virchow's doctrine, became the 29th President of Chile (1970-1973).
Virchow made himself known as a pronounced democrat in the year of revolutions in Germany (1848). His political views are evident in his Report on the Typhus Outbreak of Upper Silesia, where he states 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, which could only be achieved by "full and unlimited democracy" and "education, freedom and prosperity".
These radical statements and minor part in the revolution caused the government to remove him (1849) from his position, although within a year was reinstated as prosector 'on probation'. Prosector was a secondary position in the hospital. This secondary position in Berlin convinced him to accept the chair of pathological anatomy at the medical school in the provincial Würzburg, where he continued his scientific research. Six years later, he had attained fame at scientific and medical circles, and was reinstated at Charité Hospital.
In 1859, he became a member of the Municipal Council of Berlin and began his career as a civic reformer. Elected to the Prussian Diet in 1862, he became leader of the Radical or Progressive party; and from 1880 to 1893, he was a member of the Reichstag. He worked to improve the health-care conditions for the Berlin citizens, namely working towards modern water and sewer systems. Virchow is credited as a founder of social medicine, frequently focusing on the fact that disease is never purely biological, but often socially derived or spread, and anthropology.
The Sausage Duel
As a cofounder and member of the liberal party (Deutsche Fortschrittspartei) he was a leading political antagonist of Bismarck. He was opposed to Bismarck’s excessive military budget, which angered Bismarck sufficiently to challenge Virchow to a duel in 1865. Of the two versions, one has Virchow declining because he considered dueling an uncivilized way to solve a conflict. The second has passed into legend, but was well documented in the contemporary scientific literature. It has Virchow, having been the challenged and therefore entitled to choose the weapons, selecting two pork sausages, a normal sausage and another one, loaded with Trichinella larvae. His challenger declined the proposition as risky.
Virchow supported Bismarck in an attempt to reduce the political and social influence of the Catholic Church, between 1871 and 1887. He remarked the movement as acquiring "the character of a great struggle in the interest of humanity". He called it Kulturkampf ("culture struggle") during the discussion of Falk's May Laws (Maigesetze). 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.
In August 1850, in Berlin, Virchow married Ferdinande Rosalie Mayer (Rose Virchow; 29 February 1832 – 21 February 1913), a liberal's daughter. They had three sons and three daughters:
- Karl Virchow (1 August 1851 – 21 September 1912) – a chemist
- Hans Virchow (10 September 1852 – 7 April 1940) – a prominent anatomist
- Adele Virchow (1 October 1855 – 18 May 1955) – the wife of Rudolf Henning, a prominent professor of German studies
- Ernst Virchow (24 January 1858 – 5 April 1942)
- Marie Virchow (29 June 1866 – 23 October 1951) – the wife of Carl Rabl, a prominent Austrian anatomist
- Hanna Elisabeth Maria Virchow (10 May 1873 – 28 November 1963)
Virchow broke his thigh bone on 4 January 1902 from jumping off from a running streetcar while exiting the electric tramway. Although he anticipated full recovery, the fractured femur never healed, and restricted him of physical activity. His health gradually deteriorated and died of heart failure after eight months, on 5 September 1902, in Berlin. A state funeral was held on 9 September in the Assembly Room of the Magistracy in the Berlin Town Hall, which was decorated with laurels, palms and flowers. He was buried in the Alter St.-Matthäus-Kirchhof in Schöneberg, Berlin. His tomb was shared by his wife on 21 February 1913.
He was a very prolific writer. Some of his works are:
- Mittheilungen über die in Oberschlesien herrschende Typhus-Epidemie (1848)
- Vorlesungen über Cellularpathologie in ihrer Begründung auf physiologischer und pathologischer Gewebelehre, his chief work (1859): The fourth edition of this work formed the first volume of Vorlesungen über Pathologie below.
- Die Cellularpathologie in ihrer Begründung auf physiologische und pathologische Gewebelehre. (1858; English translation, 1860) 
- Handbuch der speciellen Pathologie und Therapie, prepared in collaboration with others (1854–76)
- Vorlesungen über Pathologie (1862–72)
