Deciding to form a new organization, Sutton arranged a meeting in August 1965 that included Curtis Henderson, Saul Kent and a designer named Karl Werner.
Curtis Henderson and Saul Kent spent October 1966 touring the United States to assist in the consolidation of the nascent cryonics movement.
On March 2, 1968, CSNY held its first Annual Cryonics Conference at the New York Academy of Sciences, a meeting attended by over one hundred people.
[4] In 1969 Cryo-Span Corporation was created to specialize in the technical and business aspects of cryopreservation, as distinct from the educational and administrative activities of CSNY.
In 1974, the State of New York Department of Public Health informed Curtis Henderson that cryonics was in violation of the law and that continued cryopreservation would be fined at a rate of $1,000 per day.
He admonished his contemporaries with aphorisms such as "There is no such thing as feelgood cryonics," meaning that optimism and faith in the future should never be allowed to distract advocates from the hard choices, challenges, and inadequacies of procedures in the real world.
