Rudolph Virchow

Rudolf Virchow was a pioneering German scientist in the 19th century who contributed significantly to cell biology and medicine. He is best known for the idea that all tissues and organs are made up of cells and that diseases originate at the cellular level. His famous phrase, "Omnis cellula e cellula," means "all cells come from pre-existing cells." Virchow’s work helped establish the foundation for modern pathology, cancer research, and understanding how diseases develop, emphasizing the importance of cellular processes in health and illness.
