Ralph Maud

Professor Maud was born in Yorkshire but moved to live in the US and Canada. He was a literary scholar who specialised in the works of Dylan Thomas and Charles Olson. It's his Welsh ancestry, his many visits to Wales, and the great teachers among his Welsh friends that gave him the authority to write a guide as a bridge to visitors to the real Wales. Ralph Maud died in 2014.
