Robert Ettinger, considered to be the "father of cryonics," went into the deep freeze after his death on Saturday. He was 92. Ettinger was the author of 'The Prospect of Immortality" (1962) in which he made the case that people could be frozen upon death and, in the future, medical technology will have advanced far enough to repair and awaken them.
