Una Marson was a pioneering Jamaican poet, dramatist, journalist, and broadcaster whose most prolific period was the 1930s, during which she divided her time between Kingston, Jamaica, and London. Marson was the first black woman to be employed by the BBC and began her job as a Programme Assistant with the Empire Service, on the programme "Calling the West Indies". She later worked on a series with George Orwell before establishing her own poetry strand "Caribbean Voices", which in later years under the direction of Henry Swanzy would introduce authors such as George Lamming, Sam Selvon, V. S. Naipaul and Edward Kamau Braithwaite to a wider audience. The programme ran for fifteen years until 1958.
