After reviewing the early work of Einstein, Weber, et al. the first mention of High-Frequency Gravitational Waves or HFGWs that I could determine was in a meeting in 1961 that I had with Dr. Robert L. Forward at my Lockheed Astrodynamics Research Center in Bel Air, California. I had invited him over from the Hughes Research Laboratory in Malibu, California to deliver a lecture on the “Weber Bar” that he and Dr. Joseph Weber were constructing at the Hughes Lab to detect Low-Frequency Gravitational Waves. After the lecture Bob and I talked about building a Laboratory generator and detector for “High-Frequency Gravitational Waves.” As far as I know this was the first time the subject had been broached. I recall that we concluded that it could not be accomplished with the technology then available.

The history of Gravitational Waves themselves predated Einstein’s 1916 paper where he discussed Gravitational Waves. Since it was in 1905, several weeks before Einstein presented his Special Theory of Relativity, that Henri Poincaré, the famous French mathematician and Celestial Mechanic, suggested that Newton’s theories needed to be modified by including “Gravitational Waves.”...
