Hartley was born in
Chester in 1929 and won a scholarship to the
King's School Chester. While still at school he took part in his first excavation, at
Heronbridge, Cheshire. In 1948 he heard a lecture by
Sir Ian Richmond who became a great influence on him. After national service in the
RAF, he studied natural sciences at
Trinity Hall, Cambridge. He then gained a diploma in prehistory and became research assistant to
Grahame Clark. He also attended the archaeological summer school at
Great Casterton run by
Graham Webster. Here he met
Philip Corder and
John Gillam whose knowledge of Roman pottery encouraged his study of
samian ware. == Archaeological career ==
