Which inventor described his job as "harnessing...the forces of nature to human needs?"

Glenn Beck is currently reading a biography on one of the unsung heroes of world history, and a key character in Miracles and Massacres. The character? Nikola Tesla. The book? My Inventions. The autobiography was formed from a six-part series that Tesla penned in 1919 in the "Electrical Experimenter" magazine. The book provides fascinating insight into the inner workings of the father of the now-ubiquitous alternating current that powers much of our lives and a variety of other life-improving technologies.
