Thomas Hennell’s Charcoal Burner was painted as a result of a commission from the War Artists Advisory Committee, established in 1939 at the instigation of Sir Kenneth Clark, Director of the National Gallery. Its aim was to compile a comprehensive artistic record of Britain throughout the war. Clark and his committee ( believed that art could capture the spirit of the war in a way that photography (which was heavily censored and often focused on hardware) could not. To achieve this, Official War Artists were appointed either on full-time or temporary contracts and by acquiring artworks from other artists.
