Kate Roberts (1891 – 1985) was one of the foremost Welsh-language authors of the 20th century. Roberts was born in the village of Rhosgadfan, Caernarfonshire, where her father was a quarryman in the local slate industry. She graduated in Welsh at the University College of North Wales, Bangor, and trained as a teacher. She taught in various schools in south Wales. She is known mainly for her short stories, but also wrote novels. Roberts was a prominent Welsh nationalist. Roberts had a literary relationship with Saunders Lewis, which they maintained through letters over a period of forty years. These letters give a picture of life in Wales during the period and the comments of these two literary giants on events at home and abroad.
