This list contains notable people who plan to be or have been cryopreserved after legal death.
Cryonics is the low-temperature freezing and storage of human remains in the hope that resurrection may be possible in the future. Cryonics is regarded with skepticism by the mainstream scientific community. It is generally viewed as a pseudoscience, and its practice has been characterized as quackery.
Robert A. Freitas Jr. is an American nanotechnologist.
Ralph C. Merkle is an American computer scientist and mathematician. He is one of the inventors of public-key cryptography, the inventor of cryptographic hashing, and more recently a researcher and speaker on cryonics.
Eliezer S. Yudkowsky is an American artificial intelligence researcher and writer on decision theory and ethics, best known for popularizing ideas related to friendly artificial intelligence. He is the founder of and a research fellow at the Machine Intelligence Research Institute (MIRI), a private research nonprofit based in Berkeley, California. His work on the prospect of a runaway intelligence explosion influenced philosopher Nick Bostrom's 2014 book Superintelligence: Paths, Dangers, Strategies.
The Alcor Life Extension Foundation, most often referred to as Alcor, is an American nonprofit, federally tax-exempt, 501(c)(3) organization based in Scottsdale, Arizona, United States. Alcor advocates for, researches, and performs cryonics, the freezing of human corpses and brains in liquid nitrogen after legal death, with hopes of resurrecting and restoring them to full health if the technology to do so becomes available in the future. Cryonics is regarded with skepticism within the scientific community and has been characterized as quackery and pseudoscience.
Robert Chester Wilson Ettinger was an American academic, known as "the father of cryonics" because of the impact of his 1962 book The Prospect of Immortality.
The Machine Intelligence Research Institute (MIRI), formerly the Singularity Institute for Artificial Intelligence (SIAI), is a non-profit research institute focused since 2005 on identifying and managing potential existential risks from artificial general intelligence. MIRI's work has focused on a friendly AI approach to system design and on predicting the rate of technology development.
James Hiram Bedford was an American psychology professor at the University of California who wrote several books on occupational counseling. He is the first person whose body was cryopreserved after legal death, and remains preserved at the Alcor Life Extension Foundation.
Michael G. Darwin, formerly known as Michael Federowicz, is a former president of cryonics organization Alcor Life Extension Foundation. He was president from 1983 to 1988, and research director until 1992. He was also the founder and president of BioPreservation, Inc., and a cofounder, member of the board of directors, and director of research at Twenty-First Century Medicine from 1993 to 1999.
Curtis Henderson was a pioneer in the practice of cryonics.
Saul Kent was a life extension activist, and co-founder of the Life Extension Foundation, a dietary supplement vendor and promoter of anti-aging research. He was also a pioneer in the practice of cryonics, and was a board member of the cryonics organization Alcor Life Extension Foundation.
Frederick Rockwell Chamberlain III and Linda Chamberlain founded the cryonics organization Alcor Life Extension Foundation. Their long and continued history of activism in cryonics make them among the most well-known cryonics pioneers. David Pascal wrote in the November/December 2005 issue of the Mensa Bulletin that, second to the man credited with the original idea for cryonics, Robert Ettinger, the Chamberlains have contributed more than anyone to the field of cryonics.
Dora Kent was the subject of a 1988 legal controversy about whether she had been murdered to facilitate her cryonic suspension. She was Alcor's eighth patient and the oldest at that time to ever be cryopreserved. She was the mother of Saul Kent, a board member of Alcor. In her earlier years, Kent worked as a dressmaker in New York City.
Dick Clair was an American television producer, actor and television and film writer, best known for the television sitcoms It's a Living, The Facts of Life, and Mama's Family.
The Singularity Summit was the annual conference of the Machine Intelligence Research Institute. It was started in 2006 at Stanford University by Ray Kurzweil, Eliezer Yudkowsky, and Peter Thiel, and the subsequent summits in 2007, 2008, 2009, 2010, 2011, and 2012 have been held in San Francisco, San Jose, New York City, San Francisco, New York City, and San Francisco respectively. Some speakers have included Sebastian Thrun, Rodney Brooks, Barney Pell, Marshall Brain, Justin Rattner, Peter Diamandis, Stephen Wolfram, Gregory Benford, Robin Hanson, Anders Sandberg, Juergen Schmidhuber, Aubrey de Grey, Max Tegmark, and Michael Shermer.
Harold Thomas Finney II was an American software developer. In his early career, he was credited as lead developer on several console games. He later worked for PGP Corporation. He was an early Bitcoin contributor, and received the first Bitcoin transaction from the currency's creator Satoshi Nakamoto.
Cryonics Institute (CI) is an American nonprofit foundation that provides cryonics services. CI freezes deceased humans and pets in liquid nitrogen with the hope of restoring them with technology in the future.
The Shandong Yinfeng Life Science Research Institute, is a life science research institute and a cryonics services provider in Jinan, Shandong, China. It was founded in 2015, and it is a division of Yinfeng Biological Group. The institute is the first organization providing cryonics services in China. In 2017, the institute made the first cryopreserved patient in China. The institute cryopreserves cells, tissues, human bodies, and animals, including dogs. The institute cooperates closely with the Shandong Yinfeng Life Science Foundation that funds the institute.
Peter Daniel Eckersley was an Australian computer scientist, computer security researcher and activist. From 2006 to 2018, he worked at the Electronic Frontier Foundation, including as chief computer scientist and head of AI policy. In 2018, he left the EFF to become director of research at the Partnership on AI, a position he held until 2020. In 2021, he co-founded the AI Objectives Institute.
