Lakhovsky's Multi-Wave Oscillator (MWO) During January, 1924, I began to build, according to this theory, and with the purpose of therapeutic applications, an apparatus, which I have called the Radio-Cellulo-Oscillator, with the firm belief that the cells vibrating at extremely short wave- lengths would find their own in the Hertzian waves, which have the properties of producing extremely short harmonics. The cell with very weak vibrations, when placed in the field of multiple radiations, finds its own frequency and starts again to oscillate normally through the phenomenon of resonance. This type of vibration are produced by the radio waves that I propose to use, is harmless, unlike those of x-rays and radium. Their application, therefore, does not present any danger for the operator. I exposed in front of my apparatus, during long periods, a certain number of microbes in culture, which developed themselves normally.

Geroges Lakhovsky published the English version of The Secret of Life at the very outbreak of World War II. His work went unnoticed and little reviewed, but Lakhovsky's reputation for obtaining dramatic results with his amazing Multi-Wave Oscillator gained world wide attention nevertheless. By 1941, he had made his way to New York, escaping the Nazi occupation of France. Mark Clement, in The Waves that Heal, describes how many people and organizations hoping to capitalize on his MWO therapy approached Lakhovsky.

A film made by an " enterprising beautician" featured several case histories of treatment with the MWO that "proved to be both interesting and convincing". Lakhovsky was also approached by several hospitals in New York hoping to test his apparatus experimentally. Remarkable results were obtained from a seven-week clinical trial performed at a major New York City hospital and that of a prominent Brooklyn urologist in the summer of 1941. Later editions of The Secret of Life detailed many of these cases.
