Ben Franklin's invention of the lightning rod and his revelation of the mysterious workings of lightning and thunder made him one of the foremost scientists of his day. As Dray, who won the Robert F. Kennedy Memorial Book Prize for At the Hands of Persons Unknown: The Lynching of Black America,
points out in this lively and entertaining tale, Franklin made his reputation as a scientist long before he established himself as a statesman. He began his experiments with electricity in the mid–18th century, when numerous European scientists were similarly engaged. Franklin wondered whether the properties of lightning were the same as those of electricity. He established a rodlike device on a hill that attracted lightning from a passing thunderstorm and conducted the current away from houses and farms and into the ground. In 1751, Franklin published a widely popular book on his observations of electricity, which won him admiration throughout Europe. Dray elegantly observes that Franklin was the first to espouse an atomic theory of electricity, which he saw as an elemental force of nature contained in all objects. Dray provides not only a masterful glimpse of this aspect of Franklin's work but also a captivating cultural history of Franklin's America. B&w illus. Agent, Geri Thoma.
