Trefor M Owen (1926–2015), former Curator at the Welsh Folk Museum (now St Fagans National History Museum) and president of the Society for Folk Life Studies, was an eminent ethnologist and anthropologist and a highly respected authority on traditional Welsh customs. He was one of the leading figures in the development of folk life as an academic discipline across the UK, and the recipient of honorary fellowships by the Folklore Society and Aberystwyth and Bangor universities in Wales. In addition to his two seminal volumes on folk traditions, he published many articles (in Welsh and English) on ethnology-related subjects. His contribution to the field is immense and enduring.
