Unstoppable: Mary Beatrice Davidson Kenner

Sobre este episódio

<p>Dr Julia Ravey and Dr Ella Hubber both have a love of science, but it turns out there’s a lot they don’t know about some of the leading women at the front of the inventing game. In Unstoppable, Dr Julia and Dr Ella tell each other the hidden, world-shaping stories of the engineers, innovators and inventors they wish they’d known about when they were starting out as scientists. This week, the inventor whose incredible capacity to solve problems inspired today’s most popular period products. </p><p>Mary Beatrice Davidson Kenner – known as Beatrice – grew up in a family of inventors, creating her first invention at just six years old. And she didn’t stop there – she continued to invent throughout her adult life, including a new and improved sanitary pad in a time when there was still a big taboo around periods. </p><p>However, as an African American woman during a time of racial segregation, Beatrice faced injustice and discrimination when trying to get her inventions patented. But if anything, this spurred Beatrice on, and at one point in time she held the most patents of any African American woman. </p><p>Dr Julia and Dr Ella are joined by Professor Sharra Vostral and Ashleigh Coren as they tell Beatrice’s remarkable story. </p><p>Presenters: Dr Ella Hubber and Dr Julia Ravey Producers: Ella Hubber and Julia Ravey Assistant producer: Sophie Ormiston Production co-ordinator: Elisabeth Tuohy Editor: Holly Squire</p>
