Jack Ernest Shalom Hayward was Professor of Politics at Hull (1973–93 and 1999–2017) and Oxford (1993–99) universities. He contributed greatly to the professionalisation of political science in Britain through his work in the Political Studies Association of which he was Chair and later President in the 1970s. He chaired the British Academy Political Studies Section between 1991 and 1994. A specialist in French and European politics and public policy as well as French social and political thought, his The One and Indivisible French Republic (1973) became a standing reference for scholars and students of France in the 1970s and 1980s. His later work additionally explored broader comparative themes in European public policy and European integration. He played a significant role in the campaign for the fair treatment of civilians interned by the Japanese during the Second World War.
