content: Oliver Shephard Barnum (1867-1928) was a graduate of Princeton University, the Albany Medical College, and the New York Homeopathic College, who lived and worked in Los Angeles. The Friedlander Company, a Chicago firm that made and sold electro-therapeutic apparatus, explained that Dr. Barnum, in 1904, “conceived the idea that if an X ray tube could be made that could energize from the Oudin resonator, valuable results might be had, by combining both X-Ray and high frequency currents, if applied simultaneously.”
