The Works of William Harvey
SYNOPSIS
William Harvey was a distinguished physician of the seventeenth century. Harvey was educated by some of the great scientists of his time and was highly knowledgeable of the scientist theories preceding his time. Harvey was greatly intrigued by the views of the ancient Aristotle and developed a number of his own ideas based on Aristotle’s theories. It was from Aristotle’s theory of the primacy of blood that allowed Harvey to make breakthroughs about circulation and generation of animals. His advancements greatly enhanced the study of anatomy. Harvey also revolutionized the means by which science was performed through the use of innovative, investigational techniques. William Harvey became a

This disproved the common view of preformation (Pagel 33). He published his final writings in the “Essays on the Generation of Animals.” After a productive and eventful life, William Harvey died in London on June 3, 1657.
Through his investigation founded on beliefs of Aristotle, William Harvey was able to hypothesize on the movement of blood in the body. Prior to William Harvey’s research , the medical view of blood in the body came from a Greek doctor by the name of Galen. Galen explained the flow of blood as a to-and-fro movement being pumped by the veins and arteries themselves. Galen also believed that blood was made and then used up in the body. His conclusions were drawn mainly from outer appearances (Bayon 444). This made Harvey’s work more accurate because he performed specific experiments and calculations. One reason Harvey was able to determine the movement of blood through the body was founded in Aristotle’s belief of the perfection of circular motion because it is continuous path (Pagel 28). William Harvey combined this idea with Arsitotle’s view of the power of the heart to act independently of the brain. From these notions, Harvey created the theory of a constant circulation of blood throughout the body by the pumping of the heart. He began researching his hypothesis with a hen’s egg. He discovered that the first drops of blood in the hen’s egg eventually gave
William Harvey published the book called “An Anatomical Account of the Motion of the Heart and Blood in Animals” which was officially published a fair time after the other two’s books. He proved that the heart acts as a pump by recirculating the blood, and showed that the blood flows around the body and is carried away by the arteries and is carried back into the heart by the veins. This had a limited impact because likewise to Vesalius, it did not make anyone healthier at the time, and it made more of a long term impact on medicine. He had not found a way to practically cure people because he had just made a book to further people’s knowledge on how the body works. Although his book is very useful for us nowadays, at the time people would not know how to approach it, and really wouldn’t make much of an impact on the people’s health.

Although there were several crucial scientists, Sir Isaac Newton, Robert Boyule, Galileo Galilei, and William Harvey, during this era their discoveries were unable to help or affect the medical technology until after the 18th century (Brandywine). Out of the 3,500 doctors in the colonies during the 18th century, some of them had a
Before the 18th century, medicine had not advanced beyond the practices of bloodletting and balancing the four humors of the body. These medical practices were not effective and did more harm than good. It was not until the Scientific Revolution that physicians slowly started to learn more about the human body and how functions. The numerous advancements of medicine in the 18th century and resulting benefits to European Society are reflected in the lack of medical practices before the 1700s, the creation of the smallpox vaccine, and improved techniques.

During the translation movement over one hundred of Galen’s writings were translated into Arabic. By translating Galen’s writings more medical professionals or aspiring physicians were able to learn what Galen discovered. Michael Servetus who was a Spanish physician discovered pulmonary circulation, and based his theory on Ibn Al-Nafis’s writings. Servetus’s theory was influenced by Galen’s, but his said that the septum of the heart did not have invisible pores, and talked about the flow of blood through the pulmonary vein and artery.
William Wilberforce was a very brave man that spoke his mind and tried to abolish slavery. He was alive during a very important time when slavery was very high, and he wanted to get rid of it. He was born on August 24, 1759, in Hull, England, to a rich business man.3 Wilberforce studied at Cambridge University. He later became an evangelical Christian.3
This new age of anatomical research led to advancements in the knowledge of the human body. Andreas Vesalius fueled the fire with his discoveries and changed the way people viewed anatomy. Some of his contradictory discoveries included:
Harvey used his studies to show how blood is pumped through the veins and arteries by the heart. In the late 1600s, Anton van Leeuwenhoek the Dutch inventor improved the microscope. Because he did so, he was able to view cells and microorganisms for the first time. Breakthroughs in medicine was
Johann Bernoulli’s two sons, which were good friends of Leonhard Euler, had convinced him to study physiology. The application of his advancement in mathematics made it much easier to comprehend. He was able to attend the lectures of the utmost elite professors at the University of Basel. After much research in the field of physiology, he decided
Most people go through life not worrying about others thoughts, just throwing stereotypes around without any justification or knowledge of the person being alienated. Some are ungrateful for the religious freedom that most of us are able to carry. Some do not realize the fight that people went through over 300 years ago to gain religious freedom and work through and around the profiling given by the hierarchy of society. No one worked harder for the freedoms to be provided and stereotypes to be dissolved than Roger Williams, the founder of Rhode Island. Williams, born in London in 1603, was a seasoned young man early on, after witnessing many burnings at the stake of puritans for being "heretics" and not following the religion of the

Robert Boyle was born at Lismore Castle, Munster on 25 January 1627, the fourteenth child and seventh son of Richard Boyle, 1st Earl of Cork. Robert Boyle was educated mainly by tutors and himself. He had no formal university education but read widely and made contact with many of the most important natural philosophers of his day, both at home and abroad. He had independent means which enabled him to have his own laboratory and to support religious charities. He was active in the ‘Invisible College’, an informal body devoted to the ‘new philosophy’ which in 1663 became the Royal Society, of which he was a Council member. He moved to Oxford in 1654, where he set up a laboratory with Robert Hooke as his assistant
