As many of you know, The Story Behind is being turned into a book, which means I’m in the process right now of doing probably one of my favorite parts of making the podcast, which is doing a ton of research in preparation. This week’s episode will be one of the chapters in the book, but the information and the inventor was one I found hard to keep to myself until the book came out. I’m your host, Emily Prokop, and this is The Story Behind the Traffic Light. www.TheStoryBehindPodcast.com
