Alfred Blalock (April 5, 1899 – September 15, 1964) was a 20th-century American surgeon most noted for his research on the medical condition of shock and for the development of the Blalock-Taussig Shunt, a surgical procedure he developed together with surgical technician Vivien Thomas and pediatric cardiologist Helen Taussig to relieve the cyanosis from Tetralogy of Fallot—known commonly as the blue baby syndrome. That operation ushered in the modern era of cardiac surgery.
