William Harvey
William Harvey (1578–1657) was an English physician and writer best known for his groundbreaking work on the circulatory system. His most famous book, "De Motu Cordis" ("On the Motion of the Heart and Blood"), published in 1628, revolutionized the understanding of how blood circulates through the body. Harvey's research, based on extensive dissections and experiments, demonstrated that the heart acts as a pump, propelling blood in a circular motion through the veins and arteries. His work laid the foundation for modern physiology and remains a cornerstone in the history of medicine.
