Lajos Kassák (March 21, 1887, Érsekújvár – July 22, 1967, Budapest) was a Hungarian poet, novelist, painter, essayist, editor, theoretician of the avant-garde, and occasional translator. He was among the first genuine working-class writers in Hungarian literature. Self-taught, he became a writer within the socialist movement and published journals important to the radical intellectual culture of Budapest in the early 1900s.
In 1953, Kassák criticised the Party's cultural politics, and was expelled from the party. Because of this, he was not allowed to publish for years, until 1956, when he was elected to be a chair in the Writers Association, an influential organization of the era. From 1957 he became practically muted by the cultural censorship of the Party, and was not allowed to travel, exhibit and publish until his death. However even in his silence, he influenced a large number of artist both in Hungary and internationally.
