GCT Giles (1891–1976) was a leading British communist, most famous for playing a central role in the evacuation of 3 million children to the countryside during the Second World War, and for playing a prominent role in the formation of Britain's post-WWII educational reform. Despite being educated at both Eton College and the University of Cambridge, he was a lifelong supporter of comprehensive schools, fighting for the rights of working-class children and teachers. He was also the first communist to be appointed president of the National Union of Teachers (NUT) and headed one of Britain's first comprehensive schools.
