Helen Brooke Taussig (May 24, 1898 – May 20, 1986) was an American cardiologist, working in Baltimore and Boston, who founded the field of pediatric cardiology. She is credited with developing the concept for a procedure that would extend the lives of children born with Tetralogy of Fallot (the most common cause of blue baby syndrome). This concept was applied in practice as a procedure known as the Blalock-Thomas-Taussig shunt. The procedure was developed by Alfred Blalock and Vivien Thomas, who were Taussig's colleagues at the Johns Hopkins Hospital.
