There is so much surrounding the history of the Radio Hypnotic Crystal that I can’t fit here, from hair tonic and patent medicine schemes to fraudulent mail-order occultism, which I’ll not only get into with future posts, but also feature the cover of one of each of the company’s six lessons, or “Branches,” at the end of each daily post. Be sure and check out yesterday’s post to get started. Professor McIntyre ran his occult correspondence course business, the Metropolitan Institute of Sciences, under the same framework as most mail fraud schemes of that time, including the system of my favorite occultist and talking board manufacturer, Theodore H. White. These schemes relied on cheap newspaper advertisements for free lucky trinkets or booklets that promised to open the door to wealth, fame, and personal power. It was all a front to harvest your address, at which point you would be bombarded with solicitations for the company’s various occult courses, lessons in hypnotism, and other products, like the Radio Hypnotic Crystal. Last post, we saw McIntyre’s proto-crystal, the “Hypnotic Ball.” At some point, very likely under the influence of our real focus here, Elmer Sidney Prather, or, as he was also known, the world-famous hypnotist Elmer E. Knowles, the Hypnotic Ball switched monikers, to the Radio Hypnotic Crystal, perhaps around 1904 when Prather invested in McIntyre’s operation. Though still labeled as McIntyre’s invention, this specimen is now more refined that the earlier Ocular Fatigue Inducer. The handle is more gracefully lathed with petite grooves, and the red sand of the previous model has been replaced with a pleasant shade of blue. It remains a glass globe, and there is at least one other specimen (in the collection of my publisher and fellow occult scholar, @erikmona) with a much more slender globe, which may date from around the same period (see my stories for a shot of this, and give Erik a follow!). Swipe through to see Prather-as-Knowles, all dashing and debonaire, as well as some shots courtesy, again, or Mr. Mona. #hypnosis #hypnotism #hypnotist #ocularfatigue #mesmerism #radiohypnoticcrystal #mesmerisme #occult #psychic #suggestion https://www.instagram.com/p/B96kEAzF_cg/?igshid=1mvrm9bm15h60
