Elwyn Stuart Richardson (8 July 1925 – 24 December 2012) was a New Zealand educator.
He is best known for his book In the Early World a record of the development of his educational philosophy while working at a small country school in Northland, New Zealand from 1949 to 1962.
On the strength of his early work, the school was granted ‘experimental status’ by Clarence Beeby, Director of Education, a special consideration that allowed him to develop his own teaching methods and curriculum largely unimpeded by school inspectors.
From 1969 to 1972 Richardson worked at American universities as a visiting lecturer.
Richardson is considered a significant figure in New Zealand education because of his own work and educational writings and the critical impact of his educational philosophy internationally.
