Ernest Barker was born in Woodley, Cheshire on 23 September 1874 and died in Cambridge on 17 February 1960. Born of humble parents, he won a scholarship to the Manchester Grammar School. From there he won scholarships to Balliol College, Oxford, where he took first class honours in classical moderations (1895), literae humaniores (1897) and modern history (1898). He became a lecturer and tutor in modern history at Oxford from 1898 until 1920. At the same time he pursued his interests in classical Greek political thought, publishing his The Political Thought of Plato and Aristotle in 1906 and Greek Political Theory: Plato and his Predecessors twelve years later. He was appointed Principal of King's College London in 1920 and (the first) Professor of Political Science at Cambridge in 1928. He retired from the post in 1939.
