Dickinson Richards was born in New Jersey, the son of a lawyer. After liberal arts studies at Yale University, Richards studied medicine at Columbia University in New York, becoming a medical doctor in 1923. Following work at Presbyterian Hospital in New York and elsewhere, in 1931 he began a prolonged collaboration with André Cournand at Bellevue Hospital and Columbia University. Dickinson Richards was married and had four children.
Even though Werner Forssmann succeeded in inserting a catheter into his own heart in 1929, there was great hesitance about continuing this type of research. Nonetheless, beginning in 1941 Dickinson Richards and André Cournand published a series of studies that established use of cardiac catheterization, among other things, to introduce contrast fluid for X-ray images and to measure pressure and oxygen content. Because it was possible to reach the upper chambers of the heart, blood pressure and the blood's oxygen content could be measured on the way from the heart to the lungs, which was impossible before.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
