Richard Rhodes, author of two of my favorite books of all time (Making of the Atomic Bomb and Dark Sun), has written a book about one of the most intriguing people of the 20th century, Hedy Lamarr, big-time Hollywood bombshell and inventor of a frequency-hopping spread-spectrum communication system.
Hedwig (Hedy) Kiesler may be one of the greatest unsung heroes of twentieth century technological progress. An opportunistic Austrian immigrant driven by curiosity and a desire to make it as a Hollywood actress in the early years of World War II, Hedy worked with avant-garde composer George Antheil to create the technology that we depend upon today for cell phones and GPS: frequency hopping. Though Richard Rhodes presents details about everyone involved in the separate experiences that the two inventors drew upon to make their breakthrough in Hedy's Folly, the invention itself takes center stage, driving the remarkable story with precision. Rhodes skillfully weaves together all the disparate parts of the story, from how Hedy learned about Nazi torpedoes to why George's knowledge of player pianos was key to the invention, in order to create a highly readable genesis of the technology that influences billions of lives every day.
