Summary 

Visitors to the Blalock Building at the Johns Hopkins University Medical Center are greeted by portraits of two great men. One, of renowned heart surgeon Alfred Blalock, speaks for itself. The other, of high school graduate Vivien Thomas, is testimony to the incredible genius and determination of the first black man to hold a professional position at one of America's premier medical institutions.  

Partners of the Heart is Thomas's extraordinary autobiography. Trained in laboratory techniques by Alfred Blalock and Joseph W. Beard, Thomas remained Blalock's principal technician and laboratory chief for the rest of Blalock's distinguished career. Thomas very rapidly learned to perform surgery, to do chemical determinations, and to carry out physiologic studies. He became a phenomenal technician and was able to carry out complicated experimental cardiac operations totally unassisted and to devise new ones.
