Yet another find on MathSciNet. Anita Feferman, Politics, Logic, and Love, MR 93j:01010, reviewed by D J Struik. This is a biography of Jean van Heijenoort. "In 1948 he broke openly with his past in a paper of [sic] the Partisan Review, where he denied the scientific nature of Marxism. He wrote it under a pseudonym (Jean Vannier) - after all he was an alien and it was the McCarthy period."
