David John Williams (26 June 1885 – 4 January 1970) was one of the foremost Welsh-language writers of the twentieth century and a prominent Welsh nationalist.
Williams was born at Pen-rhiw, a farmhouse near Llansawel, Carmarthenshire, moving with his family to a smaller farm, Abernant, near Rhydcymerau in 1891.
All his work is inspired by his vision of his native locality, of a close-knit community where common values give worth to all.
Hen Dŷ Ffarm ("The old farmhouse") was translated into English by poet Waldo Williams in 1953 as part of a UNESCO programme to promote minority languages to wider audiences.
