BALLOON-KYMOGRAPH STUDIES of esophageal motility first were reported by Kronecker and Meltzer in 1883. Meltzer came to the United States and was instrumental in founding the American Physiological Society, the Society for Experimental Biology and Medicine, and the American Society for Clinical Investigation.
