Born in the UK in 1927, Irving went on to complete his undergraduate training in geology at Cambridge. In June of 1951, he was recruited to assist British geophysicist, Keith Runcorn, whose pioneering studies of paleomagnetism provided early evidence in support of the theory of continental drift. They collected samples from the Torridonian Sandstone of Northwest Scotland for a paleomagnetic study. This work was to become the start of Irving’s PhD.
Irving was also instrumental in the early development of the magnetometer so that it could be adapted to measure rock magnetism. His 1954 PhD thesis included measurements from the Indian Deccan Traps which indicated that, since the early Tertiary, ‘India had moved from the Southern Hemisphere through 53º of latitude and had rotated counterclockwise by 28º, a motion required by (the then-controversial continental drift theory of) Wegener’.
In his last year as a PhD student at Cambridge, Irving applied to work in a research position at The Australian National University (ANU). He was offered a Research Fellowship in geophysics and arrived in Canberra in January 1955.
