A Moment in History

William S. Halsted, MD

William S. Halsted, MD
(1852 – 1922)

American anatomist, teacher, and surgeon, William Stewart Halsted was born in New York City, USA to a wealthy family of English origin. His father was involved in charitable work and Governor and trustee to a city hospital. Not a brilliant student initially, Halsted took an undergraduate in Liberal Arts in Yale, CT., after which he entered the Medical College of Physicians at the Columbia College, where he excelled.

As a second-year medical student Halsted applied and obtained a position in surgery at a local hospital. In here he learned about Lister’s antiseptic technique and became an adamant proponent of it to reduce infection. In 1877 Halsted obtained his MD. After a short time as House Physician at the New York Hospital, Halsted traveled to Europe to further his education studying for two years at the Universities of Vienna, Leipzig, and W?rzburg.

Besides being at the forefront of surgical and antiseptic techniques (introducing the use of rubber gloves in surgery), Halsted was extremely concerned with the way medical students were taught in the US. He pioneered bedside clinical round discussions with the medical students after two years of basic sciences studies. Halsted developed the idea of a patient chart; he also developed the residency program for medical students in use today.

Halsted is probably the most influential researcher and surgeon at the turn of the century. He dedicated time to the study of intestinal anastomoses and the use of silk as a suture material. His experimental work in 1887 proved that the inclusion of the submucosa layer in an anastomosis was mandatory, as well that a single layered anastomosis was enough to attain closure. Perhaps Halsted’s most important contribution was the application and use of the scientific method to surgical questions. Halsted’s principles set the standards used today in surgical suturing and surgical stapling.

He also pioneered the development and surgical techniques for radical mastectomy as a treatment for breast cancer.

As a side effect of this studied in anesthesia and the use of cocaine for anesthesia, Halsted became addicted to this substance, a problem that followed him through the years. Without impairing his capacity as a researcher and a surgeon, Halsted eventually recovered. He died in Baltimore in 1922 as a complication to surgery.

William Harvey
William Harvey

William Harvey (1578 - 1609) English physician, physiologist, and anatomist. He was born in Folklestone, where his  father was the mayor.

Harvey studied at the King’s College in Canterbury, after which he entered Cambridge. He later traveled through France and Italy and continued his studies in Padua, where he graduated with an MD in 1602. He later returned to Cambridge to complete his Doctoral studies.

He became the Physician-In-Charge at St. Bartholomew’s Hospital.  It was at this time that he started a long process of scientific observation and logical reasoning that led him to postulate the circulation of the blood in his 1628 publication  "Excercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus"  (Anatomical Exercises on the Movement of the Heart and the Blood in Animals).

Harvey’s publication caused incredible controversy, as his proposed theory went against Galen’s theories and the idea that blood passed through "invisible pores" from the right to the left atrium of the heart. His main problem was that he could not prove the presence of capillaries, which were not observed until Antoine van Leeuwenhoek invented the microscope in the late 1600's.

In his book Harvey states ''It is absolutely necessary to conclude that the blood in the animal body is impelled as in a circle and is in a state of ceaseless motion: that this is the act or function which the heart performs by means of the pulse, and that it is the sole and only end of the motion and contraction of the heart”. Even today there are many that use the term “circulatory system” without realizing that the meaning “as in a circle” coined by William Harvey is present in it.

Although the first to consider the term “circulation” was Michael Servetus (1511 – 1553), his ideas were not completely evolved. Had he completed his research and studies Servetus could have precluded Harvey, but he was considered a heretic and burnt at the stake. Thankfully, Harvey was not!
