Violet Ray Devices: A Forgotten Invention of Nikola Tesla Who is John Drakeford (the violet ray guy)?Violet Ray Devices: A Forgotten Invention of Nikola Tesla. I’ve long admired Nikola Tesla, but until a few years ago I had no idea about one of the most curious legacies of his work: the violet ray device. Tesla is among the most prolific inventors in history. He pioneered alternating current, which powers our modern world, and contributed to early X-ray imaging, wireless communication, radio, and even visionary attempts at wireless global energy transmission with his Wardenclyffe Tower. Among his many inventions, Tesla’s high-frequency “resonance transformers” — better known today as Tesla coils — laid the foundation for a class of electrotherapy devices that became famous in the early 20th century: the violet ray. How the Violet Ray Works – At the heart of a violet ray machine is a Tesla coil, which generates a high-frequency, high-voltage, but low-current electrical discharge. This current is delivered through glass electrodes filled with inert gases, usually argon or neon. When electrified, the gas produces a glowing plasma discharge. With argon, the light appears violet — hence the name. The treatment involved placing the electrode directly on the skin or holding it slightly above, allowing a gentle spark to jump to the body. Users described the sensation as a mild tingling or warmth, often accompanied by a faint ozone smell. Rise of Electrotherapy In the early 1900s, electricity was seen as a force of wonder, mystery, and untapped potential. Naturopaths, alternative healers, and even mainstream doctors were fascinated by its possibilities. An article from 1900 captured the spirit of the era when Schaefer declared: “Nothing in modern science causes us so much amazement as electricity, the sovereign ruler of all.” Manufacturers quickly capitalized on this fascination. Violet ray machines were marketed as miracle devices, capable of treating hundreds of ailments. Advertisements claimed benefits for conditions ranging from arthritis, rheumatism, poor circulation, and nervous disorders to hair loss, skin conditions, digestive issues, cataracts, and even psychiatric illnesses. Some spiritual healers, including Edgar Cayce, even suggested they could aid in cases of “possession” or mental imbalance. Home-use kits were sold alongside professional medical models. The main difference was the number and variety of glass attachments, each shaped for a particular part of the body. The literature often listed more than 200 ailments the device supposedly treated, making it one of the most widely marketed health products of its time. Decline and Controversy Despite their popularity, violet ray devices faced increasing resistance from the mainstream medical establishment, which was becoming more tightly aligned with pharmaceutical-based treatments. By the 1930s and 40s, the U.S. Food and Drug Administration began cracking down on manufacturers for unverified medical claims. Court cases, fines, and stricter regulations led to their decline. By the late 20th century, only a handful of manufacturers remained, including Holo Electron in France and Tefra in Germany. Today, only Tefra continues to produce a version of the device, though modern units use solid-state circuitry and are generally marketed for cosmetic or relaxation purposes rather than medical claims. Many enthusiasts feel these modern versions lack the power and effectiveness of their vintage predecessors. A Personal Experience For me, the violet ray story isn’t just historical curiosity — it’s personal. Years ago, I underwent four surgeries on my right shoulder for repeated glenoid labrum tears. When I later injured my left shoulder, I dreaded the prospect of going under the knife again. Around that time, I discovered violet ray devices and bought a small vintage unit. After two weeks of daily treatments, my shoulder improved dramatically. The surgery I thought was inevitable was no longer necessary. That experience lit a spark in me — I’ve been collecting, restoring, and researching these devices ever since. Over time, I’ve heard countless testimonials of people finding relief from arthritis, cystitis, and other stubborn ailments using these old machines. While modern medicine doesn’t endorse such claims, it’s hard to ignore the passion and stories of those who’ve experienced benefits first hand. Legacy of the Violet Ray The violet ray is a fascinating intersection of science, invention, and culture. It represents an era when electricity was still seen as a mystical force, a time when inventors and healers believed it could transform health and human potential. Today, these devices live on as collector’s items, curiosities, and tools for enthusiasts like myself who continue to explore their possibilities. Whether one views them as genuine therapy, quirky pseudoscience, or simply a piece of Tesla’s incredible legacy, the violet ray stands as a testament to human curiosity and our search for healing in unconventional ways. John talks about:How Nikola Tesla’s Tesla coil technology led to the creation of the violet ray device. Why violet ray machines became hugely popular in the early 1900s as electric cure-all devices. Why the violet ray faded from mainstream medicine but still has a loyal following today.
