Life Extension Society

The Life Extension Society (LES) with its network of coordinators was the first cryonics organization in the world. It was founded by Evan Cooper in 1964 to promote cryonic suspension of people, and became the seed tree for cryonics societies throughout the USA where local cryonics advocates would meet as a result of contact through the LES mailing list. The original LES ceased existence near the end of the 1960s, but an organization with the same name and similar objectives was incorporated in Maryland in 1992.
