John Saville (1916-2009) was one of the leading socialist academics of his generation, and one of the most influential figures in British labour history. This new collection of essays offers a variety of perspectives on his lifetime's work. A first section - commitments - assesses Saville's activities, at different times during his life, as a communist, as a founder of the New Left, and as editor (with Ralph Miliband) of the long-running Socialist Register. The middle section - themes - looks at key themes which mattered for Saville, from revolutionary anti-imperialism in India to the politics of Cold War and debates in labour history. In part three - interventions - contributors discuss Saville's contributions to contemporary historical understanding of Chartism, British labourism and the Cold War. The aim is to offer critical analysis and reflection in the tradition which Saville himself did so much to establish.
