Brian Sissons obituary

Brian Sissons, who has died aged 91, mapped and interpreted the effects of the Ice Age on the Scottish landscape. From the late 1950s until his retirement in 1982, Brian transformed the understanding of the evolution of Scotland's scenery.

As a fieldworker, Brian surveyed the ways in which the landscape had evolved under glacial and post-glacial conditions. His two books, The Evolution of Scotland's Scenery (1967) and The Geomorphology of the British Isles: Scotland (1976), provided a synthesis of the current knowledge. He also inspired scores of researchers, including 30 of his own PhD students, of whom I was one.
