Thunderstruck by Erik Larson. This isn't my favorite of Larson's books; however, it is an interesting look at the development of Marconi's wireless and the politics behind the success/failure of the invention, while also weaving in the story of Crippen, a man who murdered his psychologically abusive wife, which is what made wireless popular, when many doubted its usefulness.
Great Non-fiction that centers around the Chicago World's Fair of 1893! "Erik Larson's gifts as a storyteller are magnificently displayed in this rich narrative of the master builder, the killer, and the great fair that obsessed them both." ~www.bookbrowse.com
