Signers of the founding charter included two well-known Bay Area physicians, Dr. M. Coleman Harris, and Dr. Grace Talbot.
For several years thereafter, Cryovita Laboratories led by Jerry Leaf and Mike Darwin, were responsible for the initial cryonic suspension of patients of the American Cryonics Society, which were then perfused, transported, and kept in cryogenic storage by Trans Time.
[3] In 2002 when CryoSpan opted to close down its long-term cryogenic storage operations, 10 ACS patients and a number of pets were transferred to the Cryonics Institute (CI) facility in Michigan.
[4] The American Cryonics Society had contracted with CI for the long-term cryogenic storage of a number of other members prior to the 2002 patient transfer.
[5] The extra funds charged to ACS members beyond CI minimums could be used for moving the patients in the future if necessary, or other uses.
