A noteworthy review of Engineering that Made America from Horn Book Guide on October 1, 2017

Engineering That Made America series. This series takes an in-depth look at the history, conception, and practical application of key engineering feats and inventions. Each volume thoughtfully breaks down events and inspiration that led up to each invention, as well as its evolution and impact over the years. Archival photos break up the narratives. There are four other spring 2017 books in this series. Reading list, timeline. Glos., ind.
