Another tough one for me this week. My one dream/goal was to be a Medical Speech Pathologist. It took seven years of college and stress but I finally made it.

Rudolf Virchow – English
Rudolf Virchow (1821–1902) was a German physician, pathologist, anthropologist, and politician, often regarded as one of the founding figures of modern medicine. His contributions spanned both the laboratory and the social sphere, making him one of the rare scientists who influenced biology, public health, and politics at the same time.
Scientific Contributions
• Cell Theory: Virchow extended and popularized the idea that all living organisms are made of cells. His famous phrase “Omnis cellula e cellula” (“Every cell originates from another cell”) laid the foundation for modern cellular pathology.
• Cellular Pathology (1858): In his groundbreaking book, Virchow argued that diseases are not caused by imbalances of the body’s “humors” (the ancient Galenic view), but rather by disturbances in normal cellular function. This shifted the focus of medical science from organs and tissues to the cellular level.
• Thrombosis and Embolism: He was the first to describe the process by which blood clots form and travel through the circulatory system. The concept of Virchow’s triad—stasis, endothelial injury, and hypercoagulability—remains central in understanding thrombosis today.
• Public Health: Virchow emphasized that medicine was as much a social science as a biological one. He advocated for hygiene, clean water, proper sewage systems, and social reforms to combat epidemics such as typhus and cholera.
Political and Social Role
Virchow served as a member of the Prussian parliament and was an outspoken liberal. He believed poverty and inequality were root causes of poor health and argued that governments had an obligation to improve living conditions. His reports on typhus epidemics revealed the direct link between disease and social conditions, shaping the future of social medicine.
Legacy
Virchow is remembered not only as the father of cellular pathology but also as a pioneer of public health and social medicine. His insistence that science must serve society influenced generations of physicians, scientists, and reformers. His work bridges the gap between laboratory discoveries and real-world application, making him one of the most influential medical thinkers of the 19th century.

Rudolf Virchow – Hrvatski
Rudolf Virchow (1821.–1902.) bio je njemački liječnik, patolog, antropolog i političar, često smatran jednim od utemeljitelja moderne medicine. Njegov rad obuhvaćao je i laboratorijska istraživanja i društveni angažman, pa je spajao biologiju, javno zdravstvo i politiku na jedinstven način.
Znanstveni doprinosi
• Teorija stanice: Virchow je proširio i učvrstio spoznaju da su svi organizmi građeni od stanica. Njegova znamenita rečenica „Omnis cellula e cellula” („Svaka stanica potječe od druge stanice”) postavila je temelje moderne stanične patologije.
• Stanična patologija (1858.): U istoimenoj knjizi Virchow je ustvrdio da bolesti ne nastaju zbog poremećaja tjelesnih „sokova” (kako se vjerovalo od antičkih vremena), nego zbog promjena u normalnom radu stanica. Time je medicinsku znanost usmjerio sa organa i tkiva na staničnu razinu.
• Tromboza i embolija: Prvi je opisao nastanak krvnih ugrušaka i njihovo širenje krvotokom. Njegov pojam Virchowova trijada—zastoj krvi, oštećenje endotela i sklonost zgrušavanju—i danas je temelj razumijevanja tromboze.
• Javno zdravstvo: Virchow je naglašavao da je medicina jednako društvena koliko i prirodna znanost. Zalagao se za higijenu, čistu vodu, kanalizaciju i društvene reforme kako bi se spriječile epidemije poput tifusa i kolere.
Politička i društvena uloga
Bio je zastupnik u pruskom parlamentu i glasni liberal. Smatrao je da su siromaštvo i društvena nejednakost glavni uzroci lošeg zdravlja, pa je vladu pozivao da poboljša životne uvjete građana. Njegova izvješća o epidemijama tifusa pokazala su izravnu vezu bolesti i društvenih okolnosti, čime je utemeljio socijalnu medicinu.
Nasljeđe
Virchow se pamti ne samo kao otac stanične patologije, nego i kao začetnik javnog zdravstva i socijalne medicine. Njegovo uvjerenje da znanost mora služiti društvu oblikovalo je generacije liječnika, znanstvenika i reformatora. Time je postao jedan od najutjecajnijih medicinskih mislilaca 19. stoljeća.

A digital slide of a bone marrow aspirate is shown. In the left panel, a single ring vector was selected such that it exhibited high specificity for immature PMNs (bands), with this vector being depicted in the inset at the bottom right. The far majority of bands were correctly identified (circled in red). In the panel at the right, a single vector was selected such that it exhibited high specificity for normoblasts (also circled in red).
