Until the 17th century, two separate systems were thought to be involved in blood circulation: the natural system, containing venous blood which had its origin in the liver, and the vital system, containing arterial blood and the 'spirits' which flowed from the heart, distributing heat and life to all parts. Like bellows, it was thought the lungs fanned and cooled this vital blood. Having this simple but essential mathematical proportion at hand – which proved the overall impossible aforementioned role of the liver – Harvey went on to prove how the blood circulated in a circle by means of countless experiments initially done on serpents and fish: tying their veins and arteries in separate periods of time, Harvey noticed the modifications which occurred; indeed, as he tied the veins, the heart would become empty, while as he did the same to the arteries, the organ would swell up.

Harvey graduated as a Bachelor of Arts from Caius in 1597. [7] He then travelled through France and Germany to Italy, where he entered the University of Padua, in 1599. Harvey’s knowledge came from observations he made of blood flowing through the veins and arteries of living animals that he cut open. Through modern eyes, his living dissections look cruel, and there were no anesthetics in Harvey’s time. Nevertheless, it is how we arrived at an understanding of blood and its circulation in the body. Hieronymus Fabricius. Fabricius held a strong interest in Aristotelian views on the formation of the fetus and the function of valves in the veins. It is said that Fabricius had the single most influence on Harvey’s way of thought, influence that would later be observed in his research. Harvey received his degree on 25 April 1602.

I must admit that my interest in William Harvey stems in part from the fact that he was a scholar of classics. He was fluent in Greek and Latin. He studied classical literature and was a passionate reader of Greek and Roman authors. Both of his books, De Motu Cordis and De Generatione Animalium, were written in Latin. I love classics. I remember that the principal of my middle school used to say that the best engineers and scientists come from humanistic schools that emphasize classical subjects. He was absolutely right, because classical studies teach one how to think and how to express oneself. Power, D'Arcy (1897). William Harvey: Masters of Medicine. T. Fisher Unwin.

Yet, he was deeply traditional, steeped in functional anatomy, in no way the mechanist he was later made out to be. By 1616 he was lecturing on the motions of the heart, expounding his views based on dissection and vivisection about the events of the cardiac cycle and the relation between cardiac and arterial systole and diastole.

As the historian W. E. Burns points out, "The path of the blood through the body was one of the oldest and most complex problems in medicine, and its eventual solution by William Harvey was considered the most important medical and biological discovery of the scientific revolution" (63). Harvey's Methodology Harvey had seven brothers and two sisters, and his father, Thomas Harvey, was a farmer and landowner. Harvey attended the King’s School in Canterbury, Kent, from 1588 to 1593 and went on to study arts and medicine at Gonville and Caius College, Cambridge, from 1593 to 1599. He continued his studies at the University of Padua, the leading European medical school at the time. He became a student of Italian anatomist and surgeon Hieronymous Fabricius, who had a considerable influence on Harvey. It is also likely that Harvey was taught by Italian philosopher Cesare Cremonini, a prominent follower of Aristotle. the circulation mechanism is designed for movement of liquid, not air. The blood on the right side, although carrying air, is still blood During the English Civil War a mob of citizen-soldiers opposed to the King entered Harvey's lodgings, stole his goods, and scattered his papers. The papers consisted of "the records of a large number of dissections ... of diseased bodies, with his observations on the development on insects, and a series of notes on comparative anatomy." [29] During this period, Harvey maintained his position, helped the wounded on several occasions and protected the King's children during the Battle of Edgehill. [30]

By now, preparing the final version of the book on generation, Harvey had seen a great deal of the controversy over the circulation and had failed to convince major figures like Riolan and Hofmann. He had come to despair of philosophical sceptics and the neoteric philosophers. As an old man he now wanted to defend his method of acquiring knowledge—what we would call research—which he believed had helped him in his discovery of the circulation and which he felt to be threatened as Aristotle's natural philosophy was vanishing from the schools. Accordingly a part of De generatione animalium was given over to a consideration of how many observations of sensory particulars could lead to the creation of a universal in the mind. Harvey now argued that philosophical induction could indeed lead to universals, which could in turn produce a kind of demonstration. Harvey earned his doctorate from Padua on April 25, 1602, and then returned to England to work as a doctor. In 1604 he married Elizabeth Browne, the daughter of Launcelot Browne, a London physician, who served as physician to James I, the king of England and Scotland. Harvey and his wife appear to have been happy together, and Harvey referred to her as “my dear deceased loving wife” in his will. However, they did not have any children. Harvey was a fellow of the Royal College of Physicians of London from 1607 and was active in this society for the remainder of his life. In 1615 he was appointed Lumleian lecturer in surgery at the Royal College, a post he held until 1656 (the Lumleian lecture series was named after Lord John Lumley). In 1609 he was appointed physician at St. Bartholomew’s Hospital, a post he held until 1643, when the parliamentary authorities in London had him replaced, Harvey being a staunch supporter of the monarchy. Physician to the king To us, free thinkers of the 21st century, it is astounding that these extravagant ideas were not challenged for one-and-a-half millennia. It would have been easy to test them experimentally, but no one dreamed of doing that for 1500 years—a great demonstration of the power of the principle of authority, which was the mindset that dominated the Middle Ages. In 1615, aged 37, Harvey became the College of Physicians’ Lumleian Lecturer, specializing in teaching surgery. In this role, he gave an annual series of lectures, while continuing his work at St Bartholomew’s Hospital. Harvey understood these objections. Although an Aristotelian, he could not give a final cause of circulation and was driven to say that it had to be enough to show that a thing is, despite being unable to say what it is for. He had no convincing answer to the charge of destroying the basis of medical practice. Harvey's doctrine, because radical, was isolated; opponents such as Primrose could use all the authority and arguments of Galenic physiology and its vehicle, an Aristotelian natural philosophy, that reached and explained all the phenomena of the physical world.

English physician William Harvey was appointed physician to James Iin 1618 and continued as physician to Charles Iupon Charles’s accession to the throne in 1625.

To show as much as may be at a glance, the whole belly for instance, and afterwards to subdivide the parts according to their positions and relations. As one of the first major innovations in natural philosophy to be put forth and accepted largely on the basis of experimental evidence, Harvey's theory of circulation helped create the prestige of experiment and experimental science in the seventeenth century.
