Get ready for the electrifying biography of Nikola Tesla--part creative genius, part mad scientist, and 100% innovator. When Nikola Tesla arrived in the United States in 1884, he didn't have much money, but he did have a letter of introduction to renowned inventor Thomas Edison. The working relationship between the two men was short lived, though, and the two scientist-inventors became harsh competitors.

His invention of the Tesla coil was instrumental in the development of radio technology. About the Author: Jim Gigliotti is a freelance writer based in Southern California.
