Episode description

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

We hear about the moment Dr Max Perutz discovered the haemoglobin structure.

Our expert is Professor Sir Alan Fersht, who is a chemist at the Medical Research Council Laboratory of Molecular Biology and knew Dr Perutz personally.

We also hear about 22 Inuit children from Greenland's indigenous population who were sent to Denmark as part of a social experiment in 1951.

Also, when mixed-raced children from the then Belgian Congo known as ‘métis’, were forcibly taken from their homes in 1953.

When an eruption of violence in Assam led to an estimated 3,000 being killed in the Nellie massacre of 1983.

Finally, the devastating impact of the 2010 tsunami in Chile and a woman who survived it.

This programme contains outdated language which some people might find offensive.
