Book excerpt: Nikola Tesla (1856–1943) was a forerunner of the electronic age and one of science's greatest unsung heroes. This book, which was written with humor and élan, provides unique insights into one of the leading figures in modern science. His research created much of the foundation for contemporary electrical and communication systems. However, Tesla's name and contributions are only faintly known today. The visionary scientist speaks for himself in this volume, originally published in a six-part series in Electrical Experimenter magazine. This edition includes the essay "The Problem of Increasing Human Energy: With Special Reference to the Harnessing of the Sun's Energy," which anticipates latter-day advances in environmental technology. Written with wit and élan, this memoir offers fascinating insights into one of the great minds of modern science.
