On 2 December 1972, Joan Wiffen, her husband, son and daughter started a camping trip. But it was far from ordinary. They were obsessed fossil-hunters and they were deep in the largest rainforest of New Zealand's north island at a spot by a river described casually in an old geological map as having “Saurian” bones.

For Joan, as she started to search for remains, it was “like opening up the Christmas stocking". At the time, scientists believed dinosaurs had not inhabited New Zealand. With the help of archive audio, Joan’s son Chris Wiffen describes how his mother, who left school at 12 and had no qualifications, would meticulously search the rainforest site and go on to find the tailbone of a theropod dinosaur – turning scientific beliefs on their head.

He describes to Josephine McDermott how his mother devised her own DIY palaeontology lab in their garage and he would visit from university to find her surrounded by acid baths where the rocks she excavated would yield their fossils. “They had visitors from world-renowned palaeontologists and they’d say ‘Oh my gosh. Look at this. Unbelievable’. And it was.”

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.
