B. L. Coombes

Bert Lewis Coombes (1893 – 1974), originally Bertie Lewis Coombs Griffiths, was an English-born writer who spent most of his working life in the coal mines of the South Wales coalfield, which provided the subject matter for much of his writing.

Born in Wolverhampton and brought up in Herefordshire, Coombes moved to Resolven before World War I. Although his father's surname was "Griffiths", the family adopted his father's middle name, "Coombs", as a surname, spelling it "Cumbes" or "Coombes".
