Editing David Bohm (section)

=== McCarthyism and leaving the United States ===
After the war, Bohm became an assistant professor at [[Princeton University]]. He also worked closely with [[Albert Einstein]] at the nearby [[Institute for Advanced Study]]. In May 1949, the [[House Un-American Activities Committee]] called upon Bohm to testify because of his previous ties to unionism and suspected communists. Bohm invoked his [[Fifth amendment rights of witness|Fifth Amendment]] right to refuse to testify, and he refused to give evidence against his colleagues.

In 1950, Bohm was arrested for refusing to answer the committee's questions. He was acquitted in May 1951, but Princeton had already suspended him. After his acquittal, Bohm's colleagues sought to have him reinstated at Princeton, but Princeton President [[Harold W. Dodds]]<ref>Russell Olwell: [http://web.mit.edu/sts/pubs/pdfs/MIT_STS_WorkingPaper_20_Olwell.pdf ''Physics and Politics in Cold War America: The Two Exiles of David Bohm''], Working Paper Number 20.

Although Einstein considered appointing him as his research assistant at the Institute, Oppenheimer (who had served as the Institute's president since 1947) "opposed the idea and [...] advised his former student to leave the country".<ref>{{Cite book | url=https://books.google.com/books?id=1TutRoSE2XcC&q=bohm+einstein+oppenheimer&pg=PR130 |title = Quantum: Einstein, Bohr, and the Great Debate about the Nature of Reality |isbn = 978-0-393-08009-4 |last1 = Kumar |first1 = Manjit |date = 2010-05-24|publisher = W.
