This is my first book. In it John Ketteringham and I tell the stories of blockbuster innovations such as Post It notes, the microwave oven, and the VCR, and the people that produced them.  Hard copies of Breakthroughs! can be found on the web.  Or you can download a free electronic copy from this website.
