Pierre Lecomte du Noüy, circa late 1930s
Pierre Lecomte du Noüy (1883, Paris – 1947) was a French biophysicist and philosopher. He is best remembered by scientists for his work on the surface tension, and other properties, of liquids. He was an associate member of the Rockefeller Institute working in Alexis Carrel's lab from 1920 through 1928, Head of the biophysics division of the Pasteur Institute, and the author of some 200 published papers. He invented the Tensiometer, a scientific apparatus that used his du Noüy ring method to measure the surface tension of liquids.
