Neal E. Miller
Born August 3, 1909; died March 23, 2002 at the age of 92.
Neal Elgar Miller was an American psychologist and neurologist who was the first to identify and promote biofeedback. He experimentally demonstrated that individuals can learn to control their heart rate and digestion in the same sense that walking is a learned activity. The evidence was based on his experiments with rats, which he trained to control these functions through a system of rewards and punishments. Initially, few scientists accepted these ideas, but gradually his theories of biofeedback gained support and are now widely accepted.
