This is sort of just a historical dump since it’s a fascinating story: The notable death people remember is the Army officer who “jumped” out of his hotel window in NYC. Years later the Watergate investigation revealed the MKULTRA program and connected it to the Army officer’s death. CIA sort of implied “yeah we were doing stuff with LSD mind control and he went crazy,” but some (like the officer’s son) believe that is also a cover story. AFAIK the son still believes his father was going to blow the whistle on some sort of chem or bio weapon development (the father was a scientist at Fort Detrick, the US military’s bioweapon development center at the time) and he was assassinated before going public.

Anyway, the son’s theory almost seems like the most believable part of the whole MKULTRA universe.

[1] Among MKULTRA’s damage is arguably the creation of the Unabomber. Ted was an unknowing test subject at Harvard where he was basically emotionally tortured by a CIA agent posing as a fellow student. He had his beliefs — which he was always strongly identified with — systematically dismantled in order to cause emotional distress.

There was plenty of unethical psychological research going on at the time, so there's no need to assume the CIA was involved at all.

Are you sure that wasn't just ergot poisoning[0]?

The way it happened doesn't really sound like classical ergot poisoning. But who knows (but them)

   But American academic Professor Steven Kaplan, who published 
   a book in 2008 on the Pont-Saint-Esprit incident, insists 
   that neither ergot nor LSD could have been responsible.

   Ergot contamination would not, he says, have affected only 
   one sack of grain in one bakery, as was claimed here. The 
   outbreak would have been far more widespread.

   He rules out LSD on the grounds that the symptoms people 
   suffered, though similar, do not quite fit the drug.

That doesn't mean it didn't happen (or that the CIA wouldn't have done such a thing -- they've done much worse), but the "evidence" is pretty thin IMHO.
