Boris Yakovlevich Podolsky (1896–1966) was a Russian-American physicist. He is best known for the 1935 quantum mechanics paper, co-authored with Albert Einstein and Nathan Rosen, on entangled wave functions and what would later become known as the Einstein–Podolsky–Rosen paradox.Naming citation (WGSBN Bull. 5, #9, 18), IAU / Minor Planet Center, via NASA/JPL
