The automobile plants of Detroit and the steelworks of Pittsburgh once defined their towns, but few service activities are undertaken at similarly large facilities. There are some exceptions, such as hospitals and universities. These institutions have shown more permanence than the firms that built assembly lines; Oxford University is seven centuries old, but the Oxford plant of Morris Motors, which opened in 1922, closed seven decades later and was demolished in 2002. The founding of Oxford’s Radcliffe Infirmary in 1770 is almost contemporaneous with the beginning of production at the Carron Works. But the Carron Works is shuttered while the modern John Radcliffe Hospital employs 11,000 people. Rochester, once synonymous with Kodak and Xerox, is now known for its university and the Eastman School of Music (a leading conservatory).
