Eugène Ionesco was a Romanian-French playwright who wrote mostly in French, and was one of the foremost figures of the French avant-garde theatre in the 20th century. Ionesco instigated a revolution in ideas and techniques of drama, beginning with his "anti play", The Bald Soprano which contributed to the beginnings of what is known as the Theatre of the Absurd, which includes a number of plays that, following the ideas of the philosopher Albert Camus, explore concepts of absurdism and surrealism. He was made a member of the Académie française in 1970, and was awarded the 1970 Austrian State Prize for European Literature, and the 1973 Jerusalem Prize.

The theatre of the absurd is a post–World War II designation for particular plays of absurdist fiction written by a number of primarily European playwrights in the late 1950s. It is also a term for the style of theatre the plays represent. The plays focus largely on ideas of existentialism and express what happens when human existence lacks meaning or purpose and communication breaks down. The structure of the plays is typically a round shape, with the finishing point the same as the starting point. Logical construction and argument give way to irrational and illogical speech and to the ultimate conclusion—silence.
