Patented: History of Inventions

In 1890, the Governor of New York called for a new method of capital punishment. A more modern, efficient, scientific method was being sought. There was still a buzz around the recently harnessed power of electricity, which, when delivered. at high voltage to a prisoner strapped to a chair, would do the job (though not quite, at least the first time). The terrifying prospect of the Electric Chair was also hoped to put off potential criminals. Mark Essig, author of Edison and the Electric Chair: a Story of Light and Death, tells Dallas how it came about. Mixed by Benjie Guy. Produced by Freddy Chick. Senior Producer: Charlotte Long.

This is the story of the first modern computer program and the extraordinary woman who wrote it, Klara von Neumann.The program Klara wrote was a list of numbers eight hundred odd lines long. Gibberish to look at now but to the room-sized computer she was working with, it translated into a sophisticated set of instructions telling it how to map out the path neutrons would take inside nuclear bombs.To mark International Women’s Day we’re going in search of Klara von Neumann and giving her the recognition she so richly deserves.Dallas’s guest to make this happen is Ananyo Bhattacharya. Ananyo wrote a wonderful book about John von Neumann called The Man from the Future and has championed Klara and her work.Edited by Stuart Beckwith, Produced by Freddy Chick, Senior Producer is Charlotte Long.
