Cryonics Society of New York

The Cryonics Society of New York (CSNY) was a nonprofit organization incorporated on July 13, 1965. It was founded by Harold Costello, Curtis Henderson, Saul Kent, James Sutton, and Karl Werner. CSNY became the first organization to use the word "cryonics" in its name, Werner having coined the term.

CSNY cryopreserved seven people in 1968–1974: Steven Mandell, Andrew Mihok, Ann DeBlasio, Paul Hurst, Herman Greenberg, Clara Dostal, and Michael Baburka Sr. Eventually they all thawed out. However, CSNY did not take direct responsibility for thawing a patient, but physical custody was transferred first, usually to a relative, or the relatives no longer wanted to make payments.

CSNY published two newsletters: Cryonics Reports (later Immortality) and The Immortalist's Notebook.

Beverly Greenberg, CSNY's vice president died in November 1973, and shortly thereafter CSNY ceased to function.
