Yes. But as that link point out, it was years after (and a consequence of) the Einstein–Szilard letter. When did Einstein say nuclear fission was impossible, and how was it Fermi who "promptly proved him dead wrong", as madaxe_again wrote? Edit: jsnathan at https://news.ycombinator.com/item?id=12326618 https://news.ycombinator.com/item?id=12326618 found a 1934 quote by Einstein expressing an opinion that nuclear power wasn't possible. This is after fission was already demonstrated.
