Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service.

Emerante de Pradines's son, Richard Morse, tells us about his mother’s life and her commitment to de-demonising vodou culture through her music. Haiti expert Kate Hodgson, from University College Cork in Ireland, expands on the history of the country in the 20th Century.

The story of how an Argentinian doctor was inspired to create a new treatment for heart disease and when the death of a Catholic priest sent shockwaves through El Salvador in 1977.

Plus, the memories of a survivor of the Srebrenica massacre in 1995, when thousands of Bosnian Muslims were killed by Bosnian Serb Soldiers thirty years ago.

The first female jockey to win the Melbourne Cup and Orson Welles’s famous re-telling of the War of the Worlds, which sparked mass panic in America.
