Ernest David Bell (4 June, 1915 - 21 April, 1959) was an English-born writer and curator, who was a controversial figure in Welsh arts by challanging the country's artistic heritage, but was also a supporter of young Welsh talent in the field of contemporary arts.

Bell was born in 1915 in London, to Idris Bell, translator of Welsh poetry to English, and Mabel Winifred. Privately educated in England, Bell gained his first appreciation of the arts at Merchant Taylors' School. He graduated from the Royal College of Art and joined the Egypt Exploration Society, working in Sesebi and Amarah. With the outbreak of World War II, Bell found work with the cartographical department of the Admiralty, first in England, and then in Wales, being posted to the National Library of Wales at Aberystwyth.

After the end of the war, Bell was appointed the Assistant Director of the Welsh Arts Council and in 1951 he became the curator of the Glynn Vivian Art Gallery in Swansea. In 1952, Bell, along with his father translated the works of Dafydd ap Gwilym, and he continued translating Welsh works, like his father, through-out his later life. In 1957, Bell published the work The Artist in Wales, in which he implied that Wales, as a country, did not possess a worthwhile visual cultural history. This caused a backlash from his others in the field of arts in Wales and the national media.
