In 1944, two Austrian mountaineers fled into the forbidden land of Tibet to escape from a prisoner-of-war camp in India.

Heinrich Harrer and his friend Peter Aufschnaiter spent seven years there.

Harrer became a tutor to the young Dalai Lama, Tibet’s spiritual leader.

He later wrote a famous account of his visit called Seven Years in Tibet.

Simon Watts presented and produced this episode in 2016, using interviews with Harrer from the BBC Archive.

Adriana Lestido, an Argentinian newspaper photographer, captured a mother and her young daughter raising their arms in protest in 1982.

With clenched fists and anguished faces, they were wearing white handkerchiefs tied around their heads representing the struggle for justice for the disappeared during Argentina's military dictatorship.

The photo became a symbol of the resistance and is still used today. It embodies the spirit of the Mothers of the Plaza de Mayo who would meet once a week demanding the return of their loved ones.

Adriana Lestido speaks to Reena Stanton-Sharma about capturing that iconic black and white picture.

In 1980, toxic shock syndrome (TSS) emerged as a public health crisis among women who used tampons.

There were hundreds of cases, and The Centers for Disease Control linked deaths from TSS to super-absorbent tampons.

The Food and Drug Administration responded by assembling a ‘Tampon Task Force’ in 1982 to develop safety standards.

A researcher called Nancy King Reame was recruited to run the independent laboratory testing. Her work helped establish the first national absorbency standards for tampons. Golda Arthur speaks to Nancy King Reame.
