The History of Chemistry
Chemistry is everywhere, and involves everything. But how did chemistry get to be what it is? I'm Steve Cohen, a chemist and writer, bringing you The History of Chemistry. This podcast explores the development of chemistry from prehistoric times to the present, including the people and societies who made chemistry what it is today. The History of Chemistry is for you, whether you hated chemistry in high school, or got a PhD in inorganic chemistry. We'll explore how chemistry affected art, music, language, politics and vice-versa. Whether it's ancient Greek philosophers, medieval alchemists, or modern laboratory apparatus, it's all here.

Episode 111
We return to the history of light-emitting diodes, LEDs, but now talk about the development of organic versions, OLEDs, from the secret work of Roger Partridge to the now classic publication by Ching Tang and Steven Vanslyke at Eastman Kodak. Through the 1990s, more and more colors were added, so by the mid-1990s, the first commercial OLED product was marketed by electronics firm Pioneer. We also distinguish between passive and active matrix OLEDs.
