This article demonstrates that the ‘extension’ of Owens College, Manchester – the ancestor of the University of Manchester – in 1870–73 represents an important and misunderstood moment in the history of English civic universities. The new model of governance instituted by the extension movement subsequently became normative for the civic universities, and remained largely in place throughout the twentieth century. The reformers set out to devise a model of public accountability appropriate for a public institution as distinct from a private trust. The article centres on the relationship between James Bryce and the lay leaders of the extension movement, and explores the connections between the Owens College reform, the Taunton Commission’s inquiry into the endowed grammar schools, and contests over the control of three major educational foundations in Manchester (Chetham’s Hospital, Manchester Grammar School and Hulme’s Charity).
