 Bull, meanwhile, had followed Prior to England in 1960. He was supposed to be going to Cambridge, but Prior’s suggestion that he divert to Manchester won the day. Max Cresswell joined them in Manchester a year later. A student of George Hughes and David Londey at Vic, Cresswell had accidentally come across Prior’s Formal Logic in the university library in 1957, at the end of his first undergraduate year. Excited by this discovery he also devoured Time and Modality. When he won a Commonwealth Scholarship for postgraduate study in the United Kingdom, Cresswell seized the opportunity to work with Prior. In 1963, he turned in his Ph.D., on propositional logics, and—with a strong reference from Prior—arrived back at Vic to step into Londey’s shoes. (Londey, an Australian, was returning home.) Cresswell went on to dominate New Zealand logic for the next three decades. Bull completed a Ph.D. on modal logic under Prior, in 1962, and then enrolled at Oxford to study for a DPhil under Michael Dummett. At Oxford, Bull began publishing an important series of papers developing Priorean tense and modal logics (including his 1964, 1965 and 1970—his and Krister Segerberg’s 1984 handbook entry ‘Basic Modal Logic’ is still valuable today). With two doctorates in hand, Bull worked at Birmingham and then Leeds before returning to a senior lectureship at Canterbury, at the end of 1968. From afar, Prior was stationing his men to fight for logic in his native land.
