 By about 1970 a new generation of home-grown logicians had begun to enter the post-Prior landscape. In 1971, Rob Goldblatt took up a junior lectureship in mathematics at Vic. Wellington born and bred, Goldblatt learned modal logic from lectures by Cresswell and Hughes during his second undergraduate year, and he completed his Ph.D. thesis ‘Metamathematics of Modal Logic’ under Cresswell in 1974. ‘That remarkable thesis established modal logic as a mature mathematical discipline’, Bull said. Soon Goldblatt was publishing a deluge of papers on modal logic. Also in 1974 Fred Kroon, previously one of the students in Rennie’s Prior course at Auckland, was appointed to a lectureship in the Auckland philosophy department. John Bigelow, who, as a Canterbury undergraduate, had been taught ‘terrific logic’ by Montgomery, took up a lectureship in philosophy at Vic in 1973. Another admirer of Prior, Bigelow was deeply immersed in tense and modal logic (working with Hughes on tense logic), and he later staunchly defended Prior’s presentism. When Bigelow arrived home in 1973 from his Ph.D. studies at Cambridge, he found that New Zealand had become ‘a powerhouse in logic’.
