In this episode Matt Crawford speaks with author Jeremy Zallen about his book American Lucifers: The Dark History of Artificial Light; 1750-1865. This book connects the sources of light from the early 19th century to the industries it illuminated and to the lives it shaped. Zallen connects whalers to crime in a newly brightened London and the making of candles to slave plantations in the south. A truly thought provoking read this book will stoke your thought in a unique way. I highly recommend it!
