Wightman, along with Nathan B. Chamberlain, developed the device used by William T.G. Morton  to demonstrate the use of ether at Massachusetts General Hospital on October 16, 1846.
 This was one of the first successful demonstration of ether anesthesia (although his demonstration came after those of Dr. Crawford Long's in Georgia, Morton's demonstration was the first that was widely publicized).
