Virchow, whose full name was Rudolph Carl Virchow, was a German doctor and biologist who lived from 1821 until 1901. He is known as the "father of modern pathology" and was instrumental in developing the fields of social medicine.
Virchow made many contributions to medicine and science. He is best known, however, for his work with cells. He recognized leukemia cells in patients and also helped to explain cell division. Virchow also coined the term "embolism" and studied lung cancer. He often compared humans and animals in his work, which resulted in the founding of the field of comparative pathology.
The standard autopsy procedure was also developed by Virchow. This procedure is still used, in part, when performing autopsies today.
