Hertz milestone proposal

A very good proposal and a very worthy milestone. I think it is especially meaningful that the plaque will be located in the very building where Hertz conducted his experiments. I am a bit troubled by the last phrase in the citation. Would it be better to say that he "demonstrated the fundamentals"?

We agree that Hertz demonstrated the fundamentals of high-frequency technology. But he did not only demonstrate what others accomplished prior to him. To our best knowledge Hertz himself was the first to build high-frequency transmitters and receivers, to achieve 450 MHz and to successfully work in this high-frequency area. Dieter Mlynski
