Discovering the structure of haemoglobin

Discovering the structure of haemoglobin

What was it in September of 1959 that caused an Austrian scientist to rush out from his lab and buy children's modelling clay?

Austrian born Dr Max Perutz had made one of the greatest scientific discoveries of the 20th century. For the first time, he could see what a molecule of haemoglobin looked like in 3D. Using lectures and programmes from the BBC archive, Josephine McDermott tells the story of how his fellow Cambridge University students in the UK thought he was “mad” to try and map a molecule made of 10,000 atoms, and the “appalling task” which took 22 years to complete.

It was an achievement that earned him and his colleague John Kendrew the Nobel Prize in Chemistry in 1962. It has since contributed to the study of blood diseases like sickle cell anaemia and Huntington's disease.

Eye-witness accounts brought to life by archive. Witness History is for those fascinated by the past. We take you to the events that have shaped our world through the eyes of the people who were there. For nine minutes every day, we take you back in time and all over the world, to examine wars, coups, scientific discoveries, cultural moments and much more.

Recent episodes explore everything from football in Brazil, the history of the ‘Indian Titanic’ and the invention of air fryers, to Public Enemy’s Fight The Power, subway art and the political crisis in Georgia. We look at the lives of some of the most famous leaders, artists, scientists and personalities in history, including: visionary architect Antoni Gaudi and the design of the Sagrada Familia; Michael Jordan and his bespoke Nike trainers; Princess Diana at the Taj Mahal; and Görel Hanser, manager of legendary Swedish pop band Abba on the influence they’ve had on the music industry. You can learn all about fascinating and surprising stories, such as the time an Iraqi journalist hurled his shoes at the President of the United States in protest of America’s occupation of Iraq; the creation of the Hollywood commercial that changed advertising forever; and the ascent of the first Aboriginal MP.

BR Ambedkar

BR Ambedkar

When Bhimrao Ramji Ambedkar was a schoolboy, he was not allowed to drink from the same tap as his fellow students because he was a member of what was then known as an "untouchable" caste. But he went on to become a prominent leader in the campaign for Indian independence and oversaw the writing of the Indian constitution - which made the idea of "untouchability" illegal. A hero to many, he died in December 1956.Lucy Burns hears recordings of BR Ambedkar from the BBC archives and speaks to biographer Ananya Vajpeyi.Picture: A member of the Indian Congress Party places flowers on a statue of BR Ambedkar to mark the 122nd anniversary of his birth in Amritsar on April 14, 2013 (NARINDER NANU/AFP/Getty Images)

Somalia's Islamic Courts Union

Somalia's Islamic Courts Union

A controversial Islamic movement brought a brief moment of peace to Mogadishu in 2006 after years of war. The Islamic Courts Union (ICU) came to power after defeating rapacious American-backed warlords. They had no unified ideology or leadership. Some were moderates, some were hardline Islamists. But they brought law and order to the capital unseen since civil war began in 1991. But their rule would only last for six months and from the ashes would emerge the radical militant group Al-Shabab.Photo: Somalia's Supreme Council of Islamic Courts (SCIC) militia display their flag in front of Hotel Ramadan, in Mogadishu, 15, July 2006 (STRINGER/AFP/Getty Images)
