Died 9 Oct 1996 at age 83 (born 13 Apr 1913).American anesthesiologist and inventor known for three major inventions that continue to relieve pain and suffering worldwide today. One is a very portable respirator anesthesia gas machine and resuscitator, called the Western Reserve Midget, used to deliver a short-term, general anesthetic A second came from extensive experiments in the use of anesthesia to prevent pain during childbirth, leading to the invention of the continuous caudal anesthesia techniques. Best known is his "peace gun," a pistol-shaped jet injector that enabled efficient, mass, needle-less inoculation worldwide against such diseases as small pox, measles, tuberculosis, tetanus, leprosy, polio and influenza. It can inoculate 1,000 persons per hour with several simultaneous vaccines.
