Music producer Sonny Roberts and treating diabetes

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

Sonny Roberts’ daughter tells us about how her father created the UK’s first black-owned music studio - this programme contains outdated and offensive language. Music producer and professor emerita at the School of Oriental and African Studies, Lucy Durán takes us through the history of music studios around the world.

How a Macedonian scientist’s discovery led to treatments for diabetes and obesity, and the story of the Kenyan ecologist who became the first African woman to win the Nobel Peace Prize.

Plus, the mysterious sinking of a British oil tanker in Indonesia in the the 1950s and how the first lottery scratchcard was invented by an American mathematician.

As well as the story of the first South American to win the International Surfing Association world title back in 2004.
