The heroes of this new six-part series are amazing, often unsung pioneers of science and invention. Bicycling scientist Adam Hart-Davis tells their stories and attempts to demonstrate what they did - using his own home-made apparatus.
Tonight, he travels to Bristol and the south west of England where he pays tribute to the woman who invented a bed with built-in exerciser and a breakfast maker. He also discovers how lead shot was first produced, tries laughing gas in memory of Humphry Davy and, in Gloucestershire, wields the knife Edward Jenner used to perform the first smallpox vaccination.
