Richard Bing, pioneering heart researcher, dies at 101 (USA)

"Dr. Richard J. Bing, a pioneering cardiologist whose research led to new understandings of blood flow, congenital heart disease and the mechanics of the heart, died on Monday at his home in La Cañada, Calif. He was 101. His death was confirmed by his son John. Dr. Bing, who earned his medical degree in Germany but emigrated soon after Hitler rose to power, did groundbreaking research on the physiology of the heart and kidneys for more than half a century. In the 1950s, his research made it possible to measure blood flow to the heart and determine its mechanical efficiency. In the 1960s, he developed an early version of the PET scan. His work on congenital heart disease led to the identification of a variety of cardiac malformations that surgeons were then able to treat" - New York Times
