Alfred Blalock - Top Surgeons - Best Surgeons

Alfred Blalock (April 5, 1899 � September 15, 1964) was a 20th-century American innovator in the field of medical science most noted for his research on the medical condition of shock and the development of the Blalock-Taussig Shunt, surgical relief of the cyanosis from Tetralogy of Fallot�known commonly as the blue baby syndrome�with his assistant Vivien Thomas and pediatric cardiologist Helen Taussig.

Born in Culloden, Georgia, Blalock entered Georgia Military Academy, a preparatory school for the University of Georgia, at the age of 14. Having graduated from the University of Georgia with an A.B. in 1918 at the age of 19, Blalock subsequently entered Johns Hopkins Medical School, where he roomed with, became tennis doubles partner to, and began a lifetime friendship with Tinsley Harrison. Blalock earned his medical degree at Johns Hopkins in 1922. Hoping to gain appointment to a surgical residency at Johns Hopkins due to his admiration of William S. Halsted, Blalock remained in Baltimore over the next three years, completing an internship in urology, one year of an assistant residency on the general surgical service (his contract was not renewed), and an externship in ENT. He moved to Boston, Massachusetts, in the summer of 1925 to begin a surgical residency at the Peter Bent Brigham Hospital but left for Vanderbilt "without ever unpacking [his] trunk."

In July 1925, Blalock joined his good friend Harrison at Vanderbilt University in Nashville to serve as first chief resident in surgery under Barney Brooks, who was Vanderbilt University Hospital's first Professor of Surgery and Chief of the Surgical Service. Blalock was active in teaching third- and fourth-year medical students and, as a result, was placed in charge of the surgical research laboratory. While at Vanderbilt University he worked on the nature and treatment of hemorrhagic and traumatic shock. Experimenting on dogs, he found that surgical shock resulted from the loss of blood, and he encouraged the use of blood plasma or whole blood products as treatment following the onset of shock. This research resulted in the saving of many lives during World War II. Unfortunately, Blalock met with frequent bouts of tuberculosis during his Vanderbilt years. His first paper on shock, published in 1927, was actually written by his friend Harrison based on the data that Blalock had completed but could not compile due to his illness. While at Vanderbilt in 1938, Blalock attempted to produce pulmonary hypertension in experiments joining the left subclavian artery to the left pulmonary artery. Although these experiments failed in their purpose, he returned to this idea years later.
