John G. Ramsay’s book Folding and Fracturing of Rocks was first published in 1967. It set the research agenda for, and approaches to modern structural geology. It is recognised as one of the most influential texts in the subject area and was underpinned by significant research publications by the author; its weight added to by later texts and articles. John was also an enthusiastic teacher of structural geology and many of his tutees have gone on to forge their own careers in structural geology, inspired to do so by John, his teaching and approaches. This special publication serves as a golden 50 year celebration of the book, and also of John’s life-long work and career as an innovative scientist, inspiring mentor, excellent teacher and great field structural geologist.
