It was 196 years ago when..
Rudolf Ludwig Carl Virchow (13 October 1821 – 5 September 1902) 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 progressed to the gymnasium in Köslin (now Koszalin in Poland) in 1835 with the goal to become a pastor. 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 start studying medicine mainly because he considered his voice too weak for preaching. His uncle was a high-ranking officer, which may have helped him gain admission into the most prestigious medical school of the time-a military medical school in Berlin with a selective acceptance policy.
The pope of medicine
It was from that medical school that Virchow would further develop into a physician, 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".
At the early age of 27 he was appointed to a government commission to investigate a typhus epidemic in Upper Silesia (1847-1848). At that time, typhus, typhoid, and recurrent fever were not yet clearly separated diagnostic entities. The study came at an explosive time in European and especially German history, and his report on the aetiology of the epidemic, expressed in radically antiestablishment social and political terms typified the professional radicalism of the period. 
"The logical answer to the question as to how conditions similar to those unfolded before our eyes in Upper Silesia can be prevented in the future is, therefore, very easy and simple: education, with its daughters, liberty and prosperity."
The ravages of the epidemic must have made a lasting impression on young Virchow, shaping not only his character, but also his professional perspective. He wrote in his report:
"A devastating epidemic and a terrible famine simultaneously ravaged a poor, ignorant and apathetic population. In a single year 10% of the population died in the Pless district, 6.48% of starvation combined with the epidemic, and, according to official figures, 1.3% solely of starvation. In 8 months, in the district of Rybnik, 14.3% of the population were affected by typhus, of whom 20.46% died. . . . At the beginning of the year, 3% of the population of both districts were orphans. . . ." 
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. 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 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. 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.
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 an "ignoramus" and his own student Ernst Haeckel, the leading advocate of Darwinism in Germany, as a "fool". He discredited the original specimen of Neanderthal man as nothing but that of a deformed human, and not an ancestral species. He was an agnostic. 
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 Ignaz Semmelweis' policy of hand-washing 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".Virchow said. 
In hindsight, he may be glad that he did not embark on such path.
Virchow broke his thigh bone on 4 January 1902, jumping off a running streetcar while exiting the electric tramway. Although he anticipated full recovery, the fractured femur never healed, and restricted his physical activity. His health gradually deteriorated and he 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. 
"At his death Germany would complain of having lost four great men in one: her leading pathologist, her leading anthropologist, her leading sanitarian, and her leading liberal."
