John James Osborne was an English playwright, screenwriter, actor and critic of The Establishment. The stunning success of his 1956 play Look Back in Anger transformed English theatre. In a productive life of more than 40 years, Osborne explored many themes and genres, writing for stage, film and TV. His personal life was extravagant and iconoclastic. He was notorious for the ornate violence of his language, not only on behalf of the political causes he supported but also against his own family, including his wives and children though they often gave as good as they got.
He came onto the theatrical scene at a time when British acting was enjoying a golden age, but most great plays came from the United States and France. British plays remained blind to the complexities of the postwar period. Osborne was one of the first writers to address Britain's purpose in the post-imperial age. He was the first to question the point of the monarchy on a prominent public stage. During his peak (1956-1966), he helped make contempt an acceptable and now even cliched onstage emotion, argued for the cleansing wisdom of bad behaviour and bad taste, and combined unsparing truthfulness with devastating wit.
