Austrian journalist, critic, playwright, and poet who has been compared with Juvenal and Jonathan Swift for his satiric vision and command of language. In German literature he ranks as an outstanding writer of the World War I era, but, because his work is almost untranslatably idiomatic, his talents have not been widely recognized.

Of Jewish parentage, Kraus attended the University of Vienna but abandoned his studies to earn his living as a writer. In 1899 he founded the literary and political review Die Fackel (“The Torch”), which ceased publication in 1936 with the rise of Nazism in Austria. Kraus never became associated with a particular literary movement or political persuasion.

Language, to Kraus, was of great moral as well as aesthetic importance, and he relentlessly criticized its dishonest, pretentious, or inexact use as symptomatic of the moral corruption of the age. He himself wrote with masterly precision, notably in such collections of aphorisms as Sprüche und Widersprüche (1909; “Proverbs and Contradictions”) and Nachts (1919; “Nights”) and in such essay collections as Sittlichkeit und Kriminalität (1908; “Morality and Criminality”), Literatur und Lüge (1929; “Literature and Lie”), and Die Sprache (1937; “Language”). His writing occasionally rises to apocalyptic heights, as in the lengthy satirical drama Die letzten Tage der Menschheit (1918; published 1922; “The Last Days of Mankind”), a visionary condemnation of the futility of World War I.

Kraus was the founder, editor, and from 1911 the sole author of Die Fackel, through which he achieved fame as a scathing critic of Austrian society. He gradually widened the range of his attacks from the Austrian middle classes and the Viennese liberal press to encompass all that he held responsible for what he viewed as the disintegration of the Austrian, and European, cultural traditions. His satire and mode of expression are idiosyncratic and essentially Austrian (even Viennese), but his influence has been far-reaching. He also wrote poetry (Worte in Versen, 9 vol., 1916–30), epigrams (1927), and dramatic parodies. He translated works of William Shakespeare and rediscovered the works of his compatriot Johann Nestroy.

Kraus's Werke were published in 14 volumes (1952–66).
