One or two? More like one third.

Vaksberg (1994) has a particularly interesting presentation. He notes, for example, that in a photomontage of the Bolshevik leaders taken in 1920, 22 of the 61 leaders were Jews, “and the picture did not include Kaganovich, Pyatniksky, Goloshchekin, and many others who were part of the ruling circle, and whose presence on that album page would have raised the percentage of Jews even higher” (p. 20). In addition to the very large overrepresentation of Jews at these levels, there were “a plethora of Jewish wives” among the non-Jewish leaders (p. 49), which must have heightened the Jewish atmosphere of the top levels of the government.
