What contributions did Rudolph Virchow contributed to science?

Rudolph Virchow was rather interesting scientist. He was a biologist, doctor and pathologist. His work using autopsies is still used today. He was famous for his work with others in the theory of cells, in that cells come from other cells. He described and explained many diseases but he did not agree with Darwin about the evolution of man nor did he agree with the germ theory of disease. He considered social factors such as poverty as major cause of diseases.
