Re: When was the observer effect (physics) first observed?

It seems to have been first formally stated by Heisenberg in 1958 his

that it would have been noted earlier than that.
 
The reason I'm asking is that Teilhard de Chardin effectively
describes it in his foreword to 'The Phenomenon of Man' - "Object and
subject marry and mutually transform each other in the act of
knowledge; and from now on man willy-nilly finds his own image stamped
on all he looks at."
 
Teilhard wrote that somewhere in the last 1920s/early 30s which more
or less coincides with the early days of QM. I'm wondering if Teilhard
was reflecting what those involved in QM were already talking about or
whether he arrived at this under his own steam.
 

I know we had a bit of conflict over Teilhard not long ago. I recently saw
this antiwoke douchebro James Lindsay try to take a stab at Teilhard. I
tried watching it but gave up because Lindsay is trying to forcefit
Teilhard into a weird convoluted agenda. He did a similar thing with a
video about bogeyman George Soros not long ago. Before that was Herbert
Marcuse. Before that was Foucault and postmodernism. Don’t know if you have
more stamina than I do, but here it is:

Again, I despise Lindsay but would be interested in your take on his cray
cray approach to Teilhard.
