Alexander Sutherland Neill was a Scottish educator and author known for his school, Summerhill, and its philosophy of freedom from adult coercion and community self-governance. Raised in Scotland, Neill taught at several schools before attending the University of Edinburgh in 1908–1912. He took two jobs in journalism before World War I, and taught at Gretna Green Village School in the second year of the war, writing his first book, A Dominie's Log (1915), as a diary of his life there as head teacher. He joined a Dresden school in 1921 and founded Summerhill on returning to England in 1924. Summerhill gained renown in the 1930s and then in the 1960s–1970s, due to progressive and counter-culture interest. Neill wrote 20 books. His top seller was the 1960 Summerhill, read widely in the free school movement from the 1960s.

Summerhill School is an independent boarding school in Leiston, Suffolk, England. It was founded in 1921 by Alexander Sutherland Neill with the belief that the school should be made to fit the child, rather than the other way around. It is run as a democratic community; the running of the school is conducted in the school meetings, which anyone, staff or pupil, may attend, and at which everyone has an equal vote. These meetings serve as both a legislative and judicial body. Members of the community are free to do as they please, so long as their actions do not cause any harm to others, according to Neill's principle "Freedom, not Licence." This extends to the freedom for pupils to choose which lessons, if any, they attend. It is an example of both democratic education and alternative education.
