cryonic suspension
the attempt to preserve a corpse with the intention of subsequent revival and restoration to healthy life. Dr. James H. Bedford, a retired professor of psychology who died on January 12, 1967, is thought to have been the first person to be placed in cryonic suspension (in a stainless steel chamber filled with liquid nitrogen). An estimated 250 people have since undergone the procedure upon their death. No human resuscitations from cryonic suspension have yet been reported or, as far as is known, even attempted.
