Hitler’s teeth and the Leaning Tower of Pisa

Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service. Our guest is Sahar Saleem, an Egyptian paleoradiologist specialising in using medical imaging technology to study mummies and ancient artefacts.

We start with the story a Jewish interpreter who helped guard Adolf Hitler's teeth in the final days of the Second World War.

Then, the engineering efforts to reduce the tilt of the Leaning Tower of Pisa - which kept it closed to the public for 11 years.

We hear a Nepalese activist recall the massive protests that led to the restoration of multi-party democracy in 1990.

Plus, a childhood memory of the first major surrealist exhibition in New York.

Finally, we hear of the current whereabouts of Jorge, a popular Argentine sea turtle.
