Educaionist and writer, born in Kingsmuir, Fife. He studied at Edinburgh, taught in many different schools, and was editor of New Era (1920-1). He started a community school near Salzburg, which eventually settled as Summerhill School in Leiston, Suffolk (1972), a co-educational progressive school that "began as an experiment and became a demonstration". Summerhill became a school for children, especially Americans, from higher income groups. Many pupils were "difficult" and Neill spent a lot of time in psychotherapy, at first called "private lessons". He was the most extreme and radical of British progressive schoolmasters and a great publicist, publishing over 20 books, from A Dominie's Log (1916) to Neill! Neill! Orange Peel! (1973).
