Virchow, Rudolf
Aiton's Encyclopedia (1910)
Rudolf (1821-1902), a noted German scientist. He was a native of Prussia. He studied medicine in Berlin. Virchow is one of the great names in the annals of science. He won distinction in more fields than any other man of his country. He began his work as an assistant in a hospital, from which he rose rapidly to a directing position, introducing reforms yet remembered. In politics he was a Social Democrat. He took part in the revolutionary movement of 1848. He entered the Berlin municipal council in 1869, the Prussian Diet in 1862, and the Reichstag in 1880. He had the courage to oppose Bismarck's policy from beginning to end. He was for four years an active member of the Berlin aldermanic council. During this time he took an active part in the sanitation of the city, insisting that the sewage be forced through pipes to a sandy plain on the Spree where it is employed in fertilizing vegetable gardens. Virchow's crowning claim to distinction rests, however, on his work in the field of pathology. Physicians give him credit for the establishment of the doctrine of cellular pathology, an epochal event in the history of medicine. While a layman is hardly competent to enunciate this doctrine, its fundamental features are of interest. To discuss this principle they may be stated. Every animal tissue is composed of cells and is derived from cells. No cell arises except as the offspring of a previously existing cell. Spontaneous generation of cells is unknown. Disease of the body is a disease of the cells. The cure of the body may be effected by curing the cells. The real question which the modern scientific physician puts to himself when called to treat a case is, What cells are out of order and what can be done for them?
What Has Changed in the Last Century
Aiton's summary of cellular pathology in 1910 "every animal tissue is composed of cells and is derived from cells," no cell arising except from a previous cell, disease being disease of the cells still describes the foundation of modern medicine, and Virchow's name survives in everyday clinical use (Virchow's node, Virchow's triad). Two corrections are worth making: he was not a Social Democrat but a founder and leader of the left-liberal German Progress Party, and he spent his later years resisting ideas that won, dismissing Darwinian evolution as unproven for teaching and insisting the 1856 Neander valley skull was a diseased modern human rather than an early form of man. Where 1910 asked "what cells are out of order," pathology since the 1970s has asked which genes within them are altered, cancer in particular now being read as a disease of mutated DNA in a cell lineage a refinement of Virchow's frame rather than a break with it. His suggestion that chronic irritation and inflammation can seed tumours, long out of fashion, has been taken seriously again since the 1990s.
