Post-Hypnotic Suggestion

James Richard Cocke (1863 – 1900), who had been blind since infancy, was an American physician, homeopath, and a pioneer hypnotherapist.

He was born in the South of the United States, and had been totally blind since he was an infant. His sight had been completely destroyed when acid was accidentally applied to his eyes when he was just three weeks old.
He was considered to be "highly educated"; and, despite his total blindness, "was able to go around the city at will", and "could play a piano with much skill":

Walter  Georg Groddeck ( 1866 – 1934 ) was a physician and writer regarded as a pioneer of psychosomatic medicine. German physician Georg Groddeck, who practised in Baden-Baden and was the pathfinder of psychosomatic medicine, astonished his numerous listeners and readers with his therapy connecting naturopathic treatment with psychoanalytic, suggestive and hypnotic elements. His foot and arm bath, massages and dietary cuisine are still practised today, although the bold doctrine of salvation, where he mauled his patients, is necessarily quite authoritarian, and a more reserved approach would be judged appropriate today. He said “To provide obedience [is the] foundation of medical art”.
