> In this environment, Shockley, who himself was the child of an engineer and has been criticized as a eugenicist (ie. explicitly not welcoming outsiders, despite his father speaking eight languages, and being born in London), ran a Bell research lab and was exposed to a plurality of emergent military problems to which he applied physics.

Eugenics doesn't have anything in particular to say about whether outsiders should or should not be welcomed. It makes a set of scientific claims about how heredity affects people and a set of moral claims about how people should attempt to control these effects.
