In March 1941, Una Marson began her job as a Programme Assistant with the Empire Service, the first black woman to be employed by the BBC. She had already made a stir in her native Jamaica as a poet and publisher and was a leading black political activist. Her first job at the BBC was on the programme “Calling the West Indies”. She later worked on a series with George Orwell before establishing her own poetry strand “Caribbean Voices”. This Sunday, Una Marson is being commemorated with a Blue Plaque in Southwark, where she lived for many years. Her biographer, Dr Delia Jarrett Macauley joins Jane to talk about her life and work.
