Dr. Margaret Patterson, a Scottish surgeon, visiting the US from England. Dr. Patterson's work was featured in the January 1983 issue of Omni magazine when Peter Townsend, a British rock star, went public after stopping his slide into "drugged oblivion". The article, "Brain Tuner", by Kathleen McAuliffe caught Bob Beck's attention. Dr. Patterson had developed a "black box" to help her patients with their addictions after working with Dr. H. L. Wen in Hong Kong using electroacupuncture. Dr. Wen had discovered some of his patients were overcoming addictions without severe withdrawal symptoms. Bob Beck subsequently developed his own Brain Tuner after attending a seminar in Quebec, Canada in 1982. He met a researcher who had visited Russia to learn about a device that was highly effective with addictions.
