Faraday Maxwell and the Electric Field: How Two Men Revolutionized Physics by Nancy Forbes

This is a well-written and engaging history based on the premise that Faraday, a self-taught experimentalist, had seminal insights that were noticed by a similarly brilliant mathematical genius and physicist. The idea of electromagnetic fields was born and changed the world. In the course of the book one grows to appreciate these two men at a deeper level than their ideas. The book looks at their character and there is grace at work there.
