Peter Harold Sedgwick (9 March 1934 – c. 8 September 1983) was a translator of Victor Serge, author of a number of books including PsychoPolitics and a revolutionary socialist activist.
Peter Sedgwick grew up in Liverpool and won a scholarship to Balliol College, Oxford, where he became a member of the Communist Party of Great Britain.
Christopher Hitchens called him "a noble remnant of the libertarian left"[1] and dedicated his book Letters to a Young Contrarian (2001) to Sedgwick's memory.
In his book PsychoPolitics (1982) he explained that the severe reductions in psychiatric services that were already taking place as a result of the "politically correct" conceptions of mental illness, such as those of the anti-psychiatry writers Michel Foucault, R.D.
Ben Watson (music writer) has compared the spirit of Sedgwick's work to the later campaigns of the Mad Pride movement.
