sigh The _vast_ majority of “Russian Jews” who came to the US prior to the 1960s were not from Russia at all, but from one of their colonized lands, ranging from Latvia to Romania to Poland. It seriously took me less two minutes online to find Professor Berg’s parents’ Ellis Island immigration record in 1923, which clearly lists both his parents as having been born in “Kiew” (Kyiv, Ukraine) which had been in an independent country until a few months before they left, and that they had been staying more recently in “Kishineff” (Chișinău, Moldova) prior to immigration, which was in the independent Kingdom of Romania at the time. I hate how these kinds of articles naively repeat the word “Russian” to overwrite the histories and nationalities of the independent people who live(d) in eastern Europe.
