(the first person cryogenically frozen was in 1972),
James Hiram Bedford, a former University of California-Berkeley psychology professor who died of renal cancer on Jan. 12, 1967. Bedford was the first human to be cryonically preserved—that is, frozen and stored indefinitely in the hopes that technology to revive him will one day exist. He's been at Alcor since 1991. https://en.wikipedia.org/wiki/James_Bedford
