Béla Balázs, born Herbert Béla Bauer, was a Hungarian film critic, aesthetician, writer and poet of Jewish heritage. He was a proponent of formalist film theory.

György Lukács was a Hungarian Marxist philosopher, literary historian, literary critic, and aesthetician. He was one of the founders of Western Marxism, an interpretive tradition that departed from the Soviet Marxist ideological orthodoxy. He developed the theory of reification, and contributed to Marxist theory with developments of Karl Marx's theory of class consciousness. He was also a philosopher of Leninism. He ideologically developed and organised Lenin's pragmatic revolutionary practices into the formal philosophy of vanguard-party revolution.
