The History Hour

Max Pearson presents a collection of this week's Witness History episodes from the BBC World Service. Our guest is Chiara Sangiorgio, Death Penalty Adviser at Amnesty International, who tells us about the history of the death penalty and its effectiveness.

The programme begins with two perspectives on capital punishment: Yoshikuni Noguchi recounts his time as a prison guard on death row in Japan in the 1970s; then we hear archive recordings of Albert Pierrepoint, Britain's most famous hangman.

Poland's former-Minister for Foreign Affairs, Radosław Sikorski, describes how close he came to death in the 2010 Smolensk air disaster, in which the country's President was killed.

Paul McLoone, the frontman of The Undertones, a punk-rock band, tells the bizarre story of how he became the broadcasting voice of IRA commander Martin McGuinness when the organisation was banned from British airwaves in 1988.

Finally, Karlheinz Brandenburg explains how he revolutionised the way we listen to music through his invention of the MP3.

Rudolf Brazda recounts his experience of being a gay man in a Nazi concentration camp, symbolised by the pink triangle he was forced to wear on his uniform.

Then, we hear first-hand accounts of the Indigenous American protest at Wounded Knee 50 years ago, and the assassination of Serbia's Prime Minister, Zoran Djindjic, in 2003.

We finish with two lighter stories: the world's most remote museum on the island of South Georgia and the first ever underwater sculpture park in the Caribbean.
