In Our Time

In a programme first broadcast on 12 April 2018, Melvyn Bragg and guests discuss the contribution of George Stephenson (1781-1848) and his son Robert (1803-59) to the development of the railways in the 19th Century. George became known as The Father of Railways and yet arguably Robert's contribution was even greater, with his engineering work going far beyond their collaboration. Robert is credited with the main role in the design of their locomotives. George had worked on stationary colliery steam engines and, with Robert, developed the moving steam engine Locomotion No1 for the Stockton and Darlington Railway in 1825. They produced the Rocket for the Rainhill Trials on the Liverpool and Manchester Railway in 1829. From there, the success of their designs and engineering led to the expansion of railways across Britain and around the world. with Dr Michael Bailey Railway historian and editor of the most recent biography of Robert Stephenson Julia Elton Past President of the Newcomen Society for the History of Engineering and Technology and Colin Divall Professor Emeritus of Railway Studies at the University of York Producer: Simon Tillotson This programme is a repeat.

In a programme first broadcast in May 2019, Melvyn Bragg and guests discuss Mary Shelley's (1797-1851) Gothic story of a Swiss natural philosopher, Victor Frankenstein, and the creature he makes from parts of cadavers and which he then abandons, horrified by his appearance, and never names. Rejected by all humans who see him, the monster takes his revenge on Frankenstein, killing those dear to him. Shelley started writing Frankenstein when she was 18, prompted by a competition she had with Byron and her husband Percy Shelley to tell a ghost story while they were rained in in the summer of 1816 at the Villa Diodati by Lake Geneva. The image of Mary Shelley, above, was first exhibited in 1840.

Melvyn Bragg and guests discuss the bonds that Scottish Presbyterians made between themselves and their monarchs in the 16th and 17th Centuries, to maintain their form of worship. These covenants bound James VI of Scotland to support Presbyterians yet when he became James I he was also expected to support episcopacy. That tension came to a head under Charles I who found himself on the losing side of a war with the Covenanters, who later supported Parliament before backing the future Charles II after he had pledged to support them. Once in power, Charles II failed to deliver the religious settlement the Covenanters wanted, and set about repressing them violently. Those who refused to renounce the covenants were persecuted in what became known as The Killing Times, as reflected in the image above.

Melvyn Bragg and guests discuss the theoretical physicist Dirac (1902-1984), whose achievements far exceed his general fame. To his peers, he was ranked with Einstein and, when he moved to America in his retirement, he was welcomed as if he were Shakespeare. Born in Bristol, he trained as an engineer before developing theories in his twenties that changed the understanding of quantum mechanics, bringing him a Nobel Prize in 1933 which he shared with Erwin Schrödinger. He continued to make deep contributions, bringing abstract maths to physics, beyond predicting anti-particles as he did in his Dirac Equation.

Melvyn Bragg and guests discuss the origins of horses, from their dog sized ancestors to their proliferation in the New World until hunted to extinction, their domestication in Asia and their development since. The genetics of the modern horse are the most studied of any animal, after humans, yet it is still uncertain why they only have one toe on each foot when their wider family had more, or whether speed or stamina has been more important in their evolution. What is clear, though, is that when humans first chose to ride horses, as well as eat them, the future of both species changed immeasurably.
