Witness History

When an atomic bomb was detonated over the Japanese city of Hiroshima in 1945, hundreds of thousands of people were killed and injured. Despite many survivors believing nothing would grow in the city for decades, 170 trees survived close to the epicentre and are still growing 75 years later. Green Legacy Hiroshima is a project which sends seedlings from those trees around the world, spreading a message of hope. Rachael Gillman has been speaking to Teruko Ueno who survived the bombing of Hiroshima, and her daughter Tomoko Watanabe who is a co-founder of the project.

In 1990, NASA launched the historic mission which put into orbit the Hubble Space Telescope. The orbiting observatory has revolutionized astronomy and allowed us to peer deeper than ever before into the Universe.

German-born physicist Klaus Fuchs played a key role in the development of the first atomic bomb during World War Two.

The project, known as the Manhattan Project, was led by scientist J Robert Oppenheimer at Los Alamos in the US.

But, in January 1950, Fuchs admitted passing top secret nuclear secrets to the Soviet Union and was sentenced to 14 years in jail.

His nephew Klaus Fuchs-Kittowski tells Louise Hidalgo about his uncle.

This programme was first broadcast in 2015.

The story of how a car that had originally been the idea of Nazi leader Adolf Hitler was saved by a British army officer at the end of World War Two. In August 1945 the British Army sent Major Ivan Hirst to take control of the giant Volkswagen plant in Germany, built under the Nazis to produce 'people's cars' for the German masses. Ivan Hirst persuaded the British authorities to allow production to restart of the Volkswagen Beetle, which Hitler had had designed before the war as an affordable car for ordinary Germans and which would become one of the most successful cars in the world. Louise Hidalgo has been listening to archive of Major Hirst talking about that time.
