Charles B. Olson, M.S. is the author of a pioneering paper which carefully explored the possibility of low cost, reliable chemopreservation of human brains for future reanimation. The paper is A Possible Cure for Death, Medical Hypotheses 26:77-84 (1988). A graduate of Swarthmore College, Charles teaches high school science and resides in Northern California. Olson’s paper, together with thought experiments by engineer Eric Drexler, in Engines of Creation: The Coming Era of Nanotechnology, 1986 (pages 111-113, 133-138, and 267) caused a small but influential group of scientists, scholars, and writers to seriously consider the subject of human brain preservation beginning in the 1980s.
