"This comprehensive book serves as the definitive record of Tesla's early career and his revolutionary contributions to electrical science. It was released at the height of the 'War of Currents,' documenting Tesla's pioneering work on 'Polyphase Currents' and the 'Alternating Current' (AC) motor, which eventually powered the modern world.

The book is far more than a technical manual; it includes transcripts of Tesla's famous lectures before the American Institute of Electrical Engineers, where he demonstrated high-frequency phenomena and early iterations of the famous Tesla Coil. Readers are given a front-row seat to his visionary experiments in wireless lighting and power transmission. For historians and engineers alike, this collection remains an essential primary source, capturing the moment when Tesla's 'Researches' fundamentally shifted the trajectory of human civilisation from steam to the contemporary digital age."
