Physicist Michael Pupin: Science Leads to God by Jerry Bergman, Ph.D. * Michael Idvorsky Pupin (1858–1935) was a leading American researcher who made many scientific advances, including development of the fluoroscope and an electrical transmission system for long-distance telephone communication.1 A physics professor at Columbia University for 40 years, Pupin’s many discoveries resulted in devices widely used today. Pupin’s oscillating circuit research made it possible to have simultaneous transmissions of several messages through one wire, and it was his inductance coil research that made long-distance telephone calls possible.2 Both inventions made him quite wealthy—over one million dollars for his inductance...
