"... all but one of the documented cryonic preservations prior to 1973 ended in failure, and the thawing out and disposal of the bodies.". There are a decent number of articles and documentaries on the matter.

Even now it's a fringe psuedoscience with little support or even regulation. Expecting a company to be both able and willing to pay the bill to store and freeze your body in perpetuity seems... Naïve. Looking at average company lifetimes might be a useful metric here.

I think op was refferring to the first uhhh, cryonics attempts. They were sad, I recommend giving this podcast a listen: https://www.thisamericanlife.org/354/mistakes-were-made

I'm not sure if any actual official institutions failed in this way.
