First Blood Transfusion

Samuel Pepys recorded the first blood transfusion in his celebrated Diary. On Nov. 14, 1666, Pepys wrote that Richard Lower of the Royal Society made the first direct blood transfusion from the artery of one dog to the vein of another. Mr. Lower used quills to convey the blood. Attempts to perform blood transfusions would not have been possible without the work of William Harvey, who was the first to figure out blood circulation in 1628.
