In 1982, architectural historian and cultural theorist Charles Jencks took to the stage at RIBA to deliver a polemical and playful lecture: "Postmodernism: the true inheritor of Modernism". The talk was part of a RIBA series titled The Great Debate, at a time when ‘style wars’ – especially the merits of Modernist versus Postmodernist architecture – divided the architectural intelligentsia.
