Considering I've gone well before the 50's-60's, I am going back far enough.
In general, the further you go back the more prevalent and prominent the view will be - but as i said, it was a common view of particle physicists from the era you have "gone well before".
Other things CAN pull, such as if I superglue my finger to a cup and pull it towards me.
As i've explained, the sensation (and colloquial distinction) of pull is really push. Analogously, the sensation of "sucking" with a vacuum or straw is likewise an illusion - the external air pressure is in fact doing the pushing which we experience as pulling.
Nothing can move without being pushed in classical deterministic physics.
