From a 2013 piece in Tablet about Janet Yellen becoming the new Federal Reserve head (hat tip: Greg Hood):
Yellen’s ascent to the post will also guarantee that, by the end of her first term, Jews will have occupied the Fed’s top post for three decades straight – an unprecedented run of Jewish power and influence.
Unprecedented, thought I would say having 3 Jews currently on SCOTUS (with not a single Protestant on the bench) is a pretty good run.
