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

We hear about the death of one of the oldest languages in the world, when an 85 year old woman died and took it with her in 2010.

Our expert guest is Dr Mandana Seyfeddinipur, who is the Head of the Endangered Languages Archive which endeavours to preserve languages that are disappearing at “an alarming rate.”

We also hear about the historian who helped bring a former Stasi officer to justice decades after he killed a man.

Also the moment Bolivia elected its first ever indigenous president in 2005.

The Thai couple that broke the world record for the longest kiss twice.

Plus, it’s 60 years since the controversial black activist, Malcolm X was assassinated. We hear from a man who was in the audience in New York when it happened.

This programme contains outdated and offensive language.
