Alcor Life Extension Fund is the most influential non-profit organization providing cryonics technology in the United States, and now it is the largest cryonics service provider in the United States. The Life Extension Foundation was established in 1972, and the human body was first frozen in 1976. Alco Life Extension Foundation is headquartered in Scottsdale, Arizona, USA. The organization is convinced that when cell regeneration, cloning or other technologies appear, the value of their freezing technology will be reflected, and frozen people can "come back to life".
