Physical Isolation and Marginalization in Physics: David Bohm's Cold War Exile. R. Olwell in Isis 90:738 (1999).  What the paper says!?

This text, part documentary, part essay, documents the case of David Bohm's ostracization due to his communist ties and, more importantly, his refusal to testify about it to a McCarthy committee. As a result, he lost his job (at Princeton) and then his citizenship, finding first refuge in Brazil, then Israel (there he met with Aharonov) and finally in the UK. The text discusses if such alienation is detrimental or invogirating to the scientist. It doesn't get to any strong conclusion, finding it both good and bad:

his isolation led him to explore creative alternatives to orthodox quantum mechanics but also limited his influence and audience within the mainstream physics community

The subject of marginalization is touched upon and some specifics can be learned on Bohm himself, but overall the text is more tedious than enlightning.

A nice conclusion:

many younger physicists and phi losophers of science who cite or argue about Bohm's work are unaware of his political troubles and his intellectual marginalization; he is seen simply as having been ahead of his time.
