Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service. Our guest is Dr Sarah Ward, a maritime archaeologist from the Australian National University.
We start with the discovery of the sunken Terra Nova, Scott of the Antartic's ship.
We hear from the Danish food entrepeneur Claus Meyer - a driving force behind New Nordic Cuisine.
Then, the long journey that finally took Picasso's Guernica to Spain.
Plus, the Chinese pharmacist who invented the e-cigarette.
And, the life of Echo the elephant - the star of the world's longest-running study of wild elephants in Kenya.
Finally, "fan man" James Miller and boxing's most bizarre night.
