Book Log 2018 #36: The Last Days of Night by Graham Moore

Thomas Edison and George Westinghouse engaged in one of the bigger industrial battles in US history, as they sought to gain the upper hand in electrifying America. This book tells that story, but through an unexpected character - young lawyer Paul Cravath, who Westinghouse hires to manage the various lawsuits Edison is using to try to put Westinghouse out of business.

Cravath is a real person, whose work for Westinghouse presaged his later law firm work representing several large corporations. He's also noteworthy for the system he developed to organize and run professional services, like law firms, which is still in use today. You see the beginnings of that here, which creates a kind of parallel story of invention. 

It's still a good book if all you're interested in is the fight between Edison and Westinghouse, but it's just that much more interesting when you throw in Cravath's story as well.
