Brian Simon (1915–2002) was a leading advocate of comprehensive education in the second half of the twentieth century in Britain. In the 1980s, in the face of the ideological offensive from the New Right, he firmly stood by Marxist ideals and resolutely resisted policies of the right-wing leading to the 1988 Education Reform Act. Despite this rigorous campaigning that differed from that of the Labour Party, Simon’s significance has never been properly explored. In view of this, this paper aims to (...) fill the gap by exploring Simon’s distinctive contribution to the defence of comprehensive education in the 1980s. (shrink)
