Glatshteyn made a name for himself as a pioneer of radical modernism and founded, alongside the other Yiddish luminaries, the so-called Introspectivist school of Yiddish poetry that prized aesthetic innovation over political or social concerns. After the Holocaust, Glatshteyn’s verse took a decidedly more ideological and at times mournful turn as he tried to come to terms with the destruction of Europe Jewry and its world as he knew it.
