Boris Podolsky
1896 – 1966
Born in Taganrog, emigrated to the United States in 1913, and worked with Einstein at the Institute for Advanced Study in Princeton. He wrote the actual text of the 1935 EPR paper. Einstein later complained privately that the argument had been "smothered by the formalism" in Podolsky's drafting, and restated it in his own simpler terms in subsequent years.
