I agree, that story is fascinating. In fact the shift in the 1950s in how scientists thought about psychedelics is actually what my second book (in progress) is about. The Abramson cited in that study is one of the main people I've been researching: https://en.wikipedia.org/wiki/Harold_Alexander_Abramson

So as a follow on, I know this is a long shot but if anyone reading this has family or professional connections to some of the people involved in that first generation of psychedelic research in the 1950s and early 1960s (yes, they are old now, but at least a few are still around) please get in touch with me. I've been conducting oral history interviews for the past year or two and finding out all kinds of interesting things.
