Lysergic acid diethylamide, introduced in 1938 by Albert Hofman was invented to introduce a schizophrenic state so that psychiatrists could study it further.

No it wasn't. The psychedelic effects were sheer fluke, nobody knew enough to plan something like that. Hofmann says:

I had planned the synthesis of this compound with the intention of obtaining a circulatory and respiratory stimulant (an analeptic).

(quote from his book, at LSD, My Problem Child)

The effects are nothing like schizophrenia anyway.
