Born in Ruabon, Denbighshire in 1907, Will Roberts was raised in Denbighshire and Neath, Glamorgan, before studying at Swansea School of Art. In 1945, he met fellow artist Josef Herman, and the two often painted together, Will citing him as a strong influence on his work.
He is remembered for his striking industrial landscape paintings of south Wales, and is widely acknowledged as one of Wales' modern masters.
In 1962, he won the Byng-Stamper Prize for landscape painting, and in 1992 he was awarded an honorary fellowship by University College, Swansea. There was a major retrospective of his work at the National Library of Wales, Aberystwyth, in 1994. He died in 2000, and a memorial exhibition followed at the National Library of Wales, Aberystwyth, during 2001.
